Clarification of operating details for certain software features (page 20)
A listing of software enhancements in recent releases (page 25)
A listing of software fixes included in releases M.08.51 through M.10.72 (page 145)
IMPORTANT:
3400cl switches MUST be running ROM version I.08.12 prior to loading M.10.20 or newer software. If your
switch is using a software version earlier than M.10.10, you need to install and boot the M.10.10 software
(included in the M.10.41 software package) to load the I.08.12 ROM version, before installing M.10.20 or
newer.
Security Note:
Downloading and booting software release M.08.89 or greater for the first time automatically enables
SNMP access to the hpSwitchAuth MIB objects. If this is not desirable for your network, ProCurve
recommends that you disable it after downloading and rebooting with the latest switch software. For more
information, refer to “Enforcing Switch Security” on page 10 and “Using SNMP To View and Configure
Switch Authentication Features” on page 35.
Configuration Compatibility Caution:
Configuration files created or saved using version M.10.65 or higher are NOT backward-compatible with
previous software versions. The user is advised to save a copy of the pre-M.10.65 startup-config file
BEFORE UPDATING to M.10.68 or greater, in case there is ever a need to revert back to an earlier version
of software.

The terminal emulator you are using includes the Xmodem binary transfer feature. (For
example, in the HyperTerminal application included with Windows NT, you would use the
Send File option in the Transfer dropdown menu.)
Using Xmodem and a terminal emulator, you can download a switch software file to either primary
or secondary flash using the CLI.
Syntax: copy xmodem flash [< primary | secondary >]
1. To reduce the download time, you may want to increase the baud rate in your terminal emulator
and in the switch to a value such as 115200 bits per second. (The baud rate must be the same
in both devices.) For example, to change the baud rate in the switch to 115200, execute this
command:
ProCurve (config)# console baud-rate 115200
(If you use this option, be sure to set your terminal emulator to the same baud rate.)
Changing the console baud-rate requires saving to the Startup Config with the "write memory"
command. Alternatively, you can logout of the switch and change your terminal emulator speed
and allow the switch to AutoDetect your new higher baud rate (i.e. 115200 bps)
2. Execute the following command in the CLI:
Pr oCur ve # c opy xmode m f l a s h pr i ma r y
The pr i ma r y OS i ma ge wi l l be de l e t e d. c ont i nue [ y/ n] ? Y
Pr e s s ‘ Ent e r ’ a nd s t a r t XMODEM on your hos t . . .
3. Execute the terminal emulator commands to begin the Xmodem transfer. For example, using
HyperTerminal:
a. Click on Transfer, then Send File.
b. Type the file path and name in the Filename field.
c. In the Protocol field, select Xmodem.
d. Click on the Send button.
The download can take several minutes, depending on the baud rate used in the transfer.
4. If you increased the baud rate on the switch (step 1), use the same command to return it to its
previous setting. (HP recommends a baud rate of 9600 bits per second for most applications.)
Remember to return your terminal emulator to the same baud rate as the switch.)
5. Reboot the switch.
After the switch reboots, it displays the CLI or Main Menu, depending on the Logon Default setting
last configured in the menu’s Switch Setup screen.

Saving Configurations While Using the CLI
Saving Configurations While Using the CLI
The switch operates with two configuration files:
■
Running-Config File: Exists in volatile memory and controls switch operation. Rebooting
the switch erases the current running-config file and replaces it with an exact copy of the
current startup-config file. To save a configuration change, you must save the running
configuration to the startup-config file.
■
Startup-Config File:Exists in flash (non-volatile) memory and preserves the most recently-
saved configuration as the “permanent” configuration. When the switch reboots for any
reason, an exact copy of the current startup-config file becomes the new running-config file
in volatile memory.
When you use the CLI to make a configuration change, the switch places the change in the running-
config file. If you want to preserve the change across reboots, you must save the change to the startup-
config file. Otherwise, the next time the switch reboots, the change will be lost. There are two ways
to save configuration changes while using the CLI:
■
■
Execute write memory from the Manager, Global, or Context configuration level.
When exiting from the CLI to the Main Menu, press [Y] (for Yes) when you see the “save
configuration” prompt:
Do you want to save current configuration [y/n] ?

Enforcing Switch Security
Switch Management Access Security
Enforcing Switch Security
ProCurve switches are designed as “plug and play” devices, allowing quick and easy installation in
your network. However, when preparing the switch for network operation, ProCurve strongly
recommends that you enforce a security policy to help ensure that the ease in getting started is not
used by unauthorized persons as an opportunity for access and possible malicious actions. Since
security incidents can originate with sources inside as well as outside of an organization, your switch
and network access security provisions must protect against internal and external threats while
preserving the necessary network access for authorized clients and uses.
This section provides an overview of switch management and network access security features and
applications. For information on specific features, refer to the software manuals provided for your
switch model.
Caution:
In its default configuration, the switch is open to unauthorized access of various types. ProCurve
recommends that you review this section to help ensure that you recognize the potential for
unauthorized switch and network access and are aware of the features available to help prevent
such access.
Switch Management Access Security
This section outlines provisions for protecting access to the switch’s status information configuration
settings. For more detailed information on these features, refer to the indicated manuals.
Default Settings Affecting Security
In the default configuration, switch management access is available through the following methods:
■
■
■
■
Telnet
Web-browser interface (including the ability to launch Telnet access)
SNMP access
Front-Panel access (serial port access to the console, plus resets and clearing the pass-
word(s) or current configuration)

Enforcing Switch Security
Switch Management Access Security
It is important to evaluate the level of management access vulnerability existing in your network and
take steps to ensure that all reasonable security precautions are in place. This includes both
configurable security options and physical access to the switch hardware.
Local Manager Password
In the default configuration, there is no password protection. Configuring a local Manager password
is a fundamental step in reducing the possibility of unauthorized access through the switch’s web
browser and console (CLI and Menu) interfaces. The Manager password can easily be set using the
CLI password managercommand, the Menu interface Console Passwordsoption, or the password
options under the Security tab in the web browser interface.
Inbound Telnet Access and Web Browser Access
The default remote management protocols enabled on the switch are plain text protocols, which
transferpasswords inopenorplain text thatis easilycaptured. To reduce the chancesofunauthorized
users capturing your passwords, secure and encrypted protocols such as SSH and SSL must be used
for remote access. This enables you to employ increased access security while still retaining remote
client access.
■
■
SSHv2 provides Telnet-like connections through encrypted and authenticated transactions
SSLv3/TLSv1 provides remote web browser access to the switch via encrypted paths
between the switch and management station clients capable of SSL/TLS operation.
(For information on SSH and SSL/TLS, refer to the chapters on these topics in the Advanced Traffic
Management Guide for your switch.)
Also, access security on the switch is incomplete without disabling Telnet and the standard web
browser access.Among the methods for blocking unauthorized access attempts using Telnet or the
Web browser are the following two commands:
■
■
no telnet-server: This CLI command blocks inbound Telnet access.
no web-management: This CLI command prevents use of the web browser interface
through http (port 80) server access.
If you choose not to disable Telnet and web browser access, you may want to consider using RADIUS
accounting to maintain a record of password-protected access to the switch. Refer to the chapter
titled “RADIUS Authentication and Accounting” in the Access Security Guide for your switch.
Secure File Transfers
Secure Copy and SFTP provide a secure alternative to TFTP and auto-TFTP for transferring sensitive
information such as configuration files and log information between the switch and other devices.
For more on these features, refer to the section titled “Using Secure Copy and SFTP” in the “File
Transfers” appendix of the Management and Configuration Guide for your switch.

Enforcing Switch Security
Switch Management Access Security
SNMP Access (Simple Network Management Protocol)
In the default configuration, the switch is open to access by management stations running SNMP
management applications capable of viewing and changing the settings and status data in the switch’s
MIB (Management Information Base). Thus, controlling SNMP access to the switch and preventing
unauthorized SNMP access should be a key element of your network security strategy.
General SNMP Access to the Switch. The switch supports SNMP versions 1, 2c, and 3, including
SNMP community and trap configuration. The default configuration supports versions 1 and 2c
compatibility, which uses plain text and does not provide security options. ProCurve recommends
that you enable SNMP version 3 for improved security. SNMPv3 includes the ability to configure
restricted access and to block all non-version 3 messages (which blocks version 1 and 2c unprotected
operation). SNMPv3 security options include:
•
configuring device communities as a means for excluding management access by
unauthorized stations
•
•
•
•
configuring for access authentication and privacy
reporting events to the switch CLI and to SNMP trap receivers
restricting non-SNMPv3 agents to either read-only access or no access
co-existing with SNMPv1 and v2c if necessary
For more on SNMPV3, refer to the next subsection and to the chapter titled “Configuring for Network
Management Applications” in the Management and Configuration Guide for your switch.
SNMP Access to the Switch’s Authentication Configuration MIB . A management station
running an SNMP networked device management application such as ProCurve Manager Plus
(PCM+)orHPOpenViewcanaccesstheswitch’smanagementinformationbase(MIB)forreadaccess
to the switch’s status and read/write access to the switch’s configuration. In earlier software versions,
SNMP access to the switch’s authentication configuration (hpSwitchAuth) MIB was not allowed.
However, beginning with software release M.08.89, the switch’s default configuration allows SNMP
a security risk in your network, then you should implement the following security precautions when
downloading and booting from software release M.08.89 or greater:
1. If SNMP access to the authentication configuration (hpSwitchAuth) MIB described above and
in the section titled “Using SNMP To View and Configure Switch Authentication Features” (page
35) is not desirable for your network, then immediately after downloading and booting from
the M.08.89 or greater software for the first time, use the following command to disable this
feature:
snmp-server mib hpswitchauthmib excluded

Enforcing Switch Security
Switch Management Access Security
Caution:
Downloading and booting from the M.08.89 or greater software version for the first time enables
SNMP access to the authentication configuration MIB (the default action). If SNMPv3 and other
security safeguards are not in place, the switch’s authentication configuration MIB is exposed to
unprotected SNMP access and you should use the above command to disable this access.
2. If you choose to leave the authentication configuration MIB accessible, then you should do the
following to help ensure that unauthorized workstations cannot use SNMP tools to access the
MIB:
•
•
Configure SNMP version 3 management and access security on the switch.
Disable SNMP version 2c on the switch.
Refer to “Using SNMP Tools To Manage the Switch” in the chapter titled “Configuring for Network
Management Applications” in the Management and Configuration Guide for your switch. .
Physical Access to the Switch
Physical access to the switch allows the following:
■
■
use of the console serial port (CLI and Menu interface) for viewing and changing the current
configuration and for reading status, statistics, and log messages.
use of the switch’s Clear and Reset buttons for these actions:
•
•
•
clearing (removing) local password protection
rebooting the switch
restoring the switch to the factory default configuration (and erasing any nondefault
configuration settings)
Keeping the switch in a locked wiring closet or other secure space helps to prevent unauthorized
physical access. As additional precautions, you can do the following:
■
■
Disable or re-enable the password-clearing function of the Clear button.
Configure the Clear button to reboot the switch after clearing any local usernames and
passwords.
■
■
Modify the operation of the Reset+Clear button combination so that the switch reboots, but
does not restore the switch’s factory default settings.
Disable or re-enable password recovery.

Switch Management Access Security
For the commands to implement the above actions, refer to “Front-Panel Security” in the chapter
titled “Configuring Usernames and Passwords” in the Access Security Guide for your switch.
Other Provisions for Management Access Security
Authorized IP Managers. This feature uses IP addresses and masks to determine whether to allow
management access to the switch through the network, and covers access through the following:
■
■
■
Telnet and other terminal emulation applications
The switch’s web browser interface
SNMP (with a correct community name)
Refer to the chapter titled “Using Authorized IP Managers” in the Access Security Guide for your
switch.
Secure Management VLAN. This feature creates an isolated network for managing the ProCurve
switches that offer this feature. When a secure management VLAN is enabled, CLI, Menu interface,
and web browser interface access is restricted to ports configured as members of the VLAN.
Refer to the chapter titled “Static Virtual LANs (VLANs)” in the Advanced Traffic Management Guide
for your switch.
RADIUS Authentication. For each authorizedclient, RADIUS can beused to authenticate operator
or manager access privileges on the switch via the serial port (CLI and Menu interface), Telnet, SSH,
and Secure FTP/Secure Copy (SFTP/SCP) access methods.
Refer to the chapter titled “RADIUS Authentication and Accounting” in the Access Security Guide
for your switch.
TACACS+ Authentication. This application uses a central server to allow or deny access to
TACACS-aware devices in your network. TACACS+ uses username/password sets with associated
privilege levels to grant or deny access through either the switch’s serial (console) port or remotely,
with Telnet. If the switch fails to connect to a TACACS+ server for the necessary authentication
service, it defaults to its own locally configured passwords for authentication control. TACACS+
allows both login (read-only) and enable (read/write) privilege level access.
Refer to the chapter titled “TACACS+ Authentication” in the Access Security Guide for your switch
model.
Access Control Lists (ACLs) for Management Access Protection. ACLscanbeusedtosecure

Network Access Security
Network Access Security
This section outlines provisions for protecting access through the switch to the network. For more
detailed information on these features, refer to the indicated manuals.
Access Control Lists (ACLs)
ACLs enable the switch to permit or deny the following:
■
■
any inbound IP traffic on a port
specific types of TCP or UDP traffic
While ACLs do not provide user or device authentication, or protection from malicious manipulation
of data in IP packet transmissions, ACLs can enhance network security by blocking selected IP traffic
types. This functionality can be utilized to:
■
permit or deny in-band management access by limiting or preventing the use of designated
TCP or UDP protocols
■
permit or deny unwanted IP traffic to or from specific hosts
Refer to the chapter titled “Access Control Lists (ACLs) for the Series 3400cl and Series 6400cl
Switches” in the Advanced Traffic Management Guide for your switch model.
Web and MAC Authentication
These options are designed for application on the edge of a network to provide port-based security
measures for protecting private networks and the switch itself from unauthorized access. Because
neither method requires clients to run any special supplicant software, both are suitable for legacy
systems and temporary access situations where introducing supplicant software is not an attractive
option. Both methods rely on using a RADIUS server for authentication. This simplifies access
security management by allowing you to control access from a master database in a single server. It
also means the same credentials can be used for authentication, regardless of which switch or switch
port is the current access point into the LAN. Web authentication uses a web page login to
authenticate users for access to the network. MAC authentication grants access to a secure network
by authenticating device MAC address for access to the network.
Refer to the chapter titled “Web and MAC Authentication” in the Access Security Guide for your
switch model.

Network Access Security
Secure Shell (SSH)
SSH provides Telnet-like functions through encrypted, authenticated transactions of the following
types:
■
client public-key authentication: uses one or more public keys (from clients) that must
be stored on the switch. Only a client with a private key that matches a stored public key
can gain access to the switch.
■
switch SSH and user password authentication:this option is a subset of the client public-
key authentication, and is used if the switch has SSH enabled without a login access
configured to authenticate the client’s key. In this case, the switch authenticates itself to
clients, and users on SSH clients then authenticate themselves to the switch by providing
passwords stored on a RADIUS or TACACS+ server, or locally on the switch.
■
secure copy (SC) and secure FTP (SFTP): By opening a secure, encrypted SSH session,
you can take advantage of SC and SFTP to provide a secure alternative to TFTP for
transferring sensitive switch information.
Refer to the chapter titled “Configuring Secure Shell (SSH)” in the Access Security Guide for your
switch model. For more on SC and SFTP, refer to the section titled “Using Secure Copy and SFTP”
in the “File Transfers” appendixoftheManagement and Configuration Guidefor your switch model.
Secure Socket Layer (SSLv3/TLSv1)
This feature includes use of Transport Layer Security (TLSv1) to provide remote web access to the
switch via authenticated transactions and encrypted paths between the switch and management
station clients capable of SSL/TLS operation. The authenticated type includes server certificate
authentication with user password authentication.
Refer to the chapter titled “Configuring Secure Socket Layer (SSL) in the Access Security Guide for
your switch model.
Traffic/Security Filters
These statically configured filters enhance in-band security (and improve control over access to
network resources) by forwarding or dropping inbound network traffic according to the configured
criteria. Filter options and the devices that support them are listed in the following table:

802.1X Access Control
This feature provides port-based or client-based authentication through a RADIUS server to protect
the switch from unauthorized access and to enable the use of RADIUS-based user profiles to control
client access to network services. Included in the general features are the following:
■
■
■
client-based access control supporting up to 32 authenticated clients per-port
port-based access control allowing authentication by a single client to open the port
switch operation as a supplicant for point-to-point connections to other 802.1X-aware
switches

Security Guide for your switch model.
Port Security, MAC Lockdown, MAC Lockout, and IP Lockdown
These features provide device-based access security in the following ways:
■
port security: Enables configuration of each switch port with a unique list of the MAC
addresses of devices that are authorized to access the network through that port. This
enables individual ports to detect, prevent, and log attempts by unauthorized devices to
communicate through the switch. Some switch models also include eavesdrop prevention
in the port security feature.
■
MAC lockdown: This “static addressing” feature is used as an alternative to port security
for to prevent station movement and MAC address “hijacking” by allowing a given MAC
address to use only one assigned port on the switch. MAC lockdown also restricts the client
device to a specific VLAN.
■
■
MAC lockout: This feature enables blocking of a specific MAC address so that the switch
drops all traffic to or from the specified address.
IP lockdown: Available on Series 2600 and 2800 switches only, this feature enables restric-
tion of incoming traffic on a port to a specific IP address/subnet, and denies all other traffic
on that port.
Refer to the chapter titled “Configuring and Monitoring Port Security” in the Access Security Guide
for your switch model.
Key Management System (KMS)
KMS is available in several ProCurve switch models and is designed to configure and maintain key
chains for use with KMS-capable routing protocols that use time-dependent or time-independent
keys. (A key chain is a set of keys with a timing mechanism for activating and deactivating individual

keys.) KMS provides specific instances of routing protocols with one or more Send or Accept keys
that must be active at the time of a request.
Refer to the chapter titled “Key Management System” in the Access Security Guide for your switch
model.
Connection-Rate Filtering Based On Virus-Throttling Technology
While not specifically a tool for controlling network access, this feature does help to protect the
network from attack and is recommeded for use on the network edge. It is primarily focused on the
class of worm-like malicious code that tries to replicate itself by taking advantage of weaknesses in
network applications behind unsecured ports. In this case, the malicious code tries to create a large
number of outbound IP connections on a routed interface in a short time. Connection-Rate filtering
detects hosts that are generating routed traffic that exhibits this behavior, and causes the switch to
generate warning messages and (optionally) to either throttle routed traffic from the offending hosts
or drop all traffic from the offending hosts.
Refer to the chapter titled “Virus Throttling” in the Access Security Guide for your switch model.
Identity-Driven Management (IDM)
IDM is a plug-in to ProCurve Manager Plus (PCM+) and uses RADIUS-based technologies to create
a user-centric approach to network access management and network activity tracking and moni-
toring. IDM enables control of access security policy from a central management server, with policy
enforcement to the network edge, and protection against both external and internal threats.
Using IDM, a system administrator can configure automatic and dynamic security to operate at the
network edge when a user connects to the network. This operation enables the network to distinguish
among different users and what each is authorized to do. Guest access can also be configured without
compromising internalsecurity. Thismeansthatuserscanbeidentifiedandeitherapprovedordenied
at the edge of the network instead of in the core.
Criteria for enforcing RADIUS-based security for IDM applications includes classifiers such as:
■
■
■
■
■
authorized user identity
authorized device identity (MAC address)
software running on the device
physical location in the network
time of day
Responses can be configured to support the networking requirements, user (SNMP) community,
service needs, and access security level for a given client and device.

Operating Notes for Jumbo Traffic-Handling
Clarifications and Updates
Operating Notes for Jumbo Traffic-Handling
In the Management and Configuration Guide, (Oct., 2005 version) on page 14-33 ( page 347 of the .pdf
file) where it states:
When a port is not a member of any jumbo-enabled VLAN, it drops all jumbo traffic. If the port
is receiving “excessive” inbound jumbo traffic, the port generates an Event Log message to notify
you of this condition. This same condition generates a Fault-Finder message in the Alert log of
the switch’s web browswer interface, and also increments the switch’s “Giant Rx” counter.
Note that it is the “Total Rx Errors” counter that is incremented, not the “Giant Rx” counter. On the
3400cl and 6400cl series switches, when the switch applies the jumbo MTU to a VLAN, all frames
with jumbo MTU sizes (1523 to 9220 bytes) are incremented to “Total Rx Errors”.
Non-Genuine Mini-GBIC Detection and Protection Initiative
Non-genuine ProCurve Transceivers and Mini-GBICs have been offered for sale in the marketplace.
To protect customer networks from these unsupported products, ProCurve switch software includes
the capability to detect and disable non-genuine transceivers and mini-GBICs discovered in Series
3400cl Switch ports. When a non-genuine device is discovered, the switch disables the port and
generates an error message in the Event Log.

Using Delayed Group Flush. Thisfeature continues tofilterIGMPgroupsfor aspecifiedadditional
period of time after IGMP leaves have been sent. The delay in flushing the group filter prevents
unregistered traffic from being forwarded by the server during the delay period. In practice, this is

(Data-Driven IGMP, which is enabled by default, prunes off any unregistered streams detected on the
switch.)
Syntax: igmp delayed-flush < time period >
Where leaves have been sent for IGMP groups, enables the switch to continue
to flush the groups for a specified period of time (0 - 255 seconds). This

Clarifications and Updates
General Switch Traffic Security Guideline
Setting Fast-Leave and Forced Fast-Leave from the CLI. In earlier switch models, including
the 5300xl switches, fast-leave and forced fast-leave options for a port were configured with a lengthy
setmib command. The following commands now allow a port to be configured for fast-leave or forced
fast-leave operation with a conventional CLI command instead of the setmib command. Note that
these commands must be executed in a VLAN context.
Syntax: [no] ip igmp fastleave < port-list >
Enables IGMP fast-leaves on the specified ports in the selected VLAN. In the
Config context, use the VLAN specifier, for example, vlan < vid > ip igmp
fastleave < port-list >. The no form of the command disables IGMP fast-leave.
(Default: Enabled)
[no] ip igmp forcedfastleave < port-list >
Forces IGMP Fast-Leaves on the specified ports in the selected VLAN, even
if they are cascaded. (Default: Disabled)
To view a non-default IGMP forced fast-leave configuration on a VLAN, use the show running-config
command. (The show running-config output does not include forced fast-leave if it is set to the default
of 0.)
Note
Inafutureversionofthe3400clswitchsoftware, theshowrunning-config commandoutputwillinclude
any non-default fast-leave settings configured. However, this information is not included in the output
for the M.08.53 software release.
IGMP Operating Notes.
■
On the Series 3400cl switches, the delayed group flush feature offers little additional benefit
over the IGMP data-driven feature (which is enabled by default).
■
Forced fast-leave can be used when there are multiple devices attached to a port.
General Switch Traffic Security Guideline
Where the switch is running multiple security options, it implements network traffic security based
on the OSI (Open Systems Interconnection model) precedence of the individual options, from the
lowest to the highest. The following list shows the order in which the switch implements configured
security features on traffic moving through a given port.
1. Disabled/Enabled physical port
2. MAC lockout (Applies to all ports on the switch.)

Interoperating with 802.1s Multiple Spanning-Tree
The ProCurve implementation of Multiple Spanning-Tree (MSTP) complies with the IEEE 802.1s
standard and interoperates with other devices running compliant versions of 802.1s. Note that the
ProCurve Series 9300 routing switches do not offer 802.1s-compliant MSTP. Thus, to support a
connection between a 9300 routing switch and a 3400cl switch running MSTP, configure the 9300
with either 802.1D (STP) or 802.1w (RSTP). For more information on this topic, refer to the chapter
titled “Spanning-Tree Operation” in the Advanced Traffic Management Guide for your 3400cl switch.
Rate-Limiting
The configured rate limit on a port reflects the permitted forwarding rate from the port to the switch
fabric, and is visible as the average rate of the outbound traffic originating from the rate-limited port.
(The most accurate rate-limiting is achieved when using standard 64-byte packet sizes.) Also, rate-
limiting reflects the available percentage of a port’s entire inbound bandwidth. The rate of inbound
flow for traffic of a given priority and the rate of flow from a rate-limited port to a particular queue
of an outbound port are not measures of the actual rate limit enforced on a port. Also, rate-limiting
is byte-based and is applied to the available bandwidth on a port, and not to any specific applications
running through the port. If the total bandwidth requested by all applications together is less than
the available, configured maximum rate, then no rate-limit can be applied. This situation occurs with
a number of popular throughput-testing software applications, as well as most regular network
applications.
As a performance consideration, implementing rate-limiting in heavy traffic situations involving QoS,
can affect overall performance. For more information on rate-limiting operation, refer to “Operating
Notes for Rate-Limiting” in the chapter titled “Port Traffic Controls ” of the Management and
Configuration Guide for your ProCurve Series 3400cl switch. (To download switch documentation,
refer to “Software Updates” on page 1.)

Known Issues
Release M.10.17
The following is a known issue related to installation of Release M.10.17 software, which includes a
required update to ROM version I.08.12.
When there is an active 10-GbE link in port 26 of the ProCurve 3400cl-24G switch, or port 50 of the
ProCurve 3400cl-48G switch, there may be a problem with that link initializing following a software
update into the required M.10.17 software version. For customers with a console connection to the
switch during the boot process, there may also be a false report with one or more of the following
messages:
This switch needs replacement during next scheduled downtime?or,
Module selftest failure or,
Workarounds: Ifthisisamission-criticalswitchandthe softwareisbeingupdatedremotelythrough
a 10-GbE link in port 26 or 50, it is recommended that you have someone onsite with the switch able
to directly communicate with the switch from another port or the console connection. The issue may
be avoided by enabling the “fastboot” feature and using the “reload” command after updating to
M.10.17 ( refer to “Install Recommendations for I.08.12 Boot ROM Update” on page 6)
If the problem persists, it may also be possible to re-initialize the link by administratively disabling
and re-enabling both the affected port and the port that is directly connected to it. If those steps fail
to resolve the problem, try disconnecting the media from the potentially affected port until after the
switch is running M.10.17. The port should then initialize.
Fix: There is a fix associated with software version M.10.20. Once the switch has been updated to
software version M.10.17, update to software version M.10.20 and reboot.
Note that M.10.10 does not have the same issue related to installation of Release M.10.17 software.

DNS Resolver for using DNS names for Ping and Traceroute
RADIUS Configuration via SNMP (see “Using SNMP To View and Configure Switch
Authentication Features” on page 35)
DNS Resolver
The Domain Name System (DNS) resolver is designed for use in local network domains where it
enables use of a host name or fully qualified domain name to perform ping and traceroute operations
from the switch.
Terminology
Domain Suffix — Includes all labels to the right of the unique host name in a fully qualified domain
name assigned to an IP address. For example, in the fully qualified domain name “device53.ever-
green.trees.org”, the domain suffix is “evergreen.trees.org”, while “device53” is the unique (host)
name assigned to a specific IP address.
Fully Qualified Domain Name — The sequence of labels in a domain name identifying a specific
host (host name) and the domain in which it exists. For example, if a device with an IP address
of 10.10.10.101 has a host name of device53 and resides in the evergreen.trees.org domain, then
the device’s fully qualified domain name is device53.evergreen.trees.org and the DNS resolution
of this name is 10.10.10.101.
Host Name — The unique, leftmost label in a domain name assigned to a specific IP address in a
DNS server configuration. This enables the server to distinguish a device using that IP address
from other devices in the same domain. For example, in the evergreen.trees.org domain, if an
28

Release M.08.89 Enhancements
IP address of 10.10.100.27 is assigned a host name of accounts015 and another IP address of
10.10.100.33 is assigned a host name of sales021, then the switch configured with the domain
suffix evergreen.trees.org and a DNS server that resolves addresses in that domain can use the
host names to reach the devices with ping and traceroute commands:
ping accounts015
traceroute sales021
Basic Operation
■
When the switch is configured with only the IP address of a DNS server available to the
switch, then a ping or traceroute command, executed with a fully qualified domain name, can
reach a device found in any domain accessible through the configured DNS server.
■
When the switch is configured with both of the following:
•
•
the IP address of a DNS server available to the switch
the domain suffix of a domain available to the configured DNS server
then:
•
A ping or traceroute command that includes the host name of a device in the same domain
as the configured domain suffix can reach that device.
•
A ping or traceroute command that includes a fully qualified domain name can reach a
device in any domain that is available to the configured DNS server.
Example. Suppose the switch is configured with the domain suffix mygroup.procurve.net and the IP
address for an accessible DNS server. If an operator wants to use the switch to ping a host using the
DNS name “leader” assigned to an IP address used in that domain, then the operator can use either
of the following commands:
Host Name for the Desired Host
Ping Response
ProCurve# ping leader
10.28.229.220 is alive, time = 1 ms
ProCurve# ping leader.mygroup.procurve.net
10.28.229.220 is alive, time = 1 ms
Fully Qualified Domain Name for the
Desired Host
Ping Response
Figure 3. Example of Using Either a Host Name or a Fully Qualified Domain Name
In the preceeding example, if the DNS server’s IP address is configured on the switch, but a domain
suffix is not configured, then the fully qualified domain name must be used.
Note that if the target host is in a domain other than the domain configured on the switch, then:
29

Enhancements
Release M.08.89 Enhancements
■
The host’s domain must be reachable from the switch. This requires that the DNS server for
the switch must be able to communicate with the DNS server(s) in the path to the domain
in which the target host operates.
■
The fully qualified domain name must be used, and the domain suffix must correspond to
the domain in which the target host operates, regardless of the domain suffix configured in
the switch.
Example. Suppose the switch is configured with the domain suffix mygroup.procurve.net and the IP
address for an accessible DNS server. This time, the operator wants to use the switch to trace the
route to a host named “remote-01” in another domain namedcommon.group.net. As long as this domain
is accessible to the DNS server configured on the switch, a traceroute command using the target’s
fully qualified DNS name should succeed.

Configuring and Using DNS Resolution with Ping and Traceroute Commands
1. Determine the following:
a. the IP address for a DNS server operating in a domain in your network
b. the domain name for an accessible domain in which there are hosts you want to reach with
ping and/or traceroute commands. (This is the domain suffix in the fully qualified domain
name for a given host operating in the selected domain. Refer to “Terminology” on page 28.)
Note that if a domain suffix is not configured, fully qualified domain names can be used to
resolve ping and traceroute commands.
c. the host names assigned to target IP addresses in the DNS server for the specified domain
2. Use the data from steps 1a and 1b to configure the DNS entry on the switch.
3. Use either ping or traceroute with the host names for the target devices whose connectivity you
are testing or troubleshooting.

Enhancements
Release M.08.89 Enhancements
Configuring a DNS Entry
The switch allows one DNS server entry, which includes the DNS server IP address and the chosen
domain name suffix. Configuring the entry enables the use of ping and traceroute with a target’s host
name instead of the target’s IP address.
Syntax: [no] ip dns server-address < ip-addr >
Configures the IP address of a DNS server accessible to the switch. This setting
identifies the server to use for DNS resolution to the target IP address, and must be
configured before ping or traceroute can be executed with host name criteria.
The switch supports one DNS server entry. Configuring another IP address for this
value replaces the current IP address with the new one.
The no form of the command replaces the configured IP address with the null setting,
which disables host name resolution. (Default: null)
Syntax: [no] ip dns domain-name < domain-name-suffix >
Configures the domain suffix that is automatically appended to the host name
entered with the ping or traceroute command. When the domain suffix and the DNS
server IP address are both configured on the switch, you can execute ping and
traceroute with only the host name of the desired target within the domain. In either
of the following two instances, you must manually provide the domain identifica-
tion by using a fully qualified DNS name with each ping and traceroute command:
• If the DNS server IP address is configured on the switch, but the domain suffix
is not configured (null)
• The domain suffix configured on the switch is not the domain in which the target
host exists
The switch supports one domain suffix entry. Configuring a new entry for this value
replaces the current suffix.
The no form of the command replaces the configured domain suffix with the null
setting. (Default: null)
Example Using DNS Names with Ping and Traceroute
In the network illustrated in Figure 5, the switch at 10.28.192.1 is configured to use DNS names for

Operating Notes
■
The DNS server must be accessible to the switch, but it is not necessary for any intermediate
devices between the switch and the DNS server to be configured to support DNS operation.
■
A DNS configuration must include the IP address for a DNS server that is able to resolve host
names for the desired domain. If a DNS server has limited knowledge of other domains, then
its ability to resolve ping or traceroute requests is also limited.
■
If the DNS configuration includes a DNS serverIP address but does not also include a domain
suffix, then any ping or traceroute command should include the target host’s fully qualified
domain name. Refer to Figure 3 on page 29.
■
■
The switch supports one DNS entry; that is, one DNS serverIPaddress andthe corresponding
domain name suffix.
Switch-Initiated DNS packets go out through the VLAN having the best route to the DNS
server, even if a Management VLAN has been configured.
■
■
The traceroute command output shows only IP addresses.
The DNS server address must be manually input. It is not be automatically determined via
DHCP.
■
Operation with IPv4 DNS servers has been verified and, while no problems with servers
supporting both IPv4 and IPv6 addresses are expected, testing has not been performed with
such servers. (IPv6 AAAA-style queries are not supported.)

Using SNMP To View and Configure Switch Authentication Features
In earlier software releases, SNMP MIB object accesshas not been available for switch authentication
configuration (hpSwitchAuth) features. Beginning with software release M.08.89, the 3400cl and
6400cl switches allow, by default, manager-only SNMP read/write access to a subset of the authenti-
cation MIB objects for the following features:
■
■

■
■
■
■
number of primary and secondary login and enable attempts
TACACS+ server configuration and status
RADIUS server configuration
selected 802.1X settings
key management subsystem chain configuration
key management subsystem key configuration
OSPF interface authentication configuration
With SNMP access to the hpSwitchAuth MIB enabled, a device with management access to the switch
can view the configuration for the authentication features listed above (excluding passwords and
keys). Using SNMP sets, a management device can change the authentication configuration
(including changes to passwords and keys). Operator read/write access to the authentication MIB
is always denied.

Enhancements
Release M.08.89 Enhancements
Security Notes
Passwords and keys configured in the hpSwitchAuth MIB are not returned via SNMP, and the
response to SNMP queries for such information is a null string. However, SNMP sets can be used to
configure password and key MIB objects.
To help prevent unauthorized access to the switch’s authentication MIB, ProCurve recommends
enhancing security according to the guidelines under “Enforcing Switch Security” on page 10.
If you do not want to use SNMP access to the switch’s authentication configuration MIB, then you
should use the snmp-server mib hpswitchauthmib excluded command to disable this access, as
described in the next section.
If you choose to leave SNMP access to the security MIB open (the default setting), ProCurve
recommends that you configure the switch with the SNMP version 3 management and access security
feature, and disable SNMP version 2c access. (Refer to “Enforcing Switch Security” on page 10.)

The MSTP enhancement implementing the CLI command for spanning-tree legacy-path-cost
was included in releaseM.08.90
The MSTP enhancement implementing the CLI command for spanning-tree legacy-mode
was included in release M.08.91
QoS Pass-Through Mode enhancement, a new command that allows the configuration of the
Quality of Service (QoS) queues to be selected.
MSTP Default Path Cost Controls
Summary: 802.1D and 802.1t specify different default path-cost values (based on interface speed).
These are used if the user hasn't configured a "custom" path-cost for the interface. The default of this
toggle is to use 802.1t values. The reason one might set this control to 802.1D would be for better
interoperability with legacy 802.1D STP (Spanning Tree Protocol) bridges.
To support legacy STP bridges, the following commands (options) have been added to CLI:
spanning-tree legacy-path-cost - Use 802.1D values for default path-cost
no spanning-tree legacy-path-cost - Use 802.1t values for default path-cost (default setting)
38

Enhancements
Releases M.08.90 and M.08.91 Enhancements
The “legacy-path-cost” CLI command does not affect or replace functionality of the “spanning-
tree force-version” command. The “spanning-tree force-version” controls whether MSTP will
send and process 802.1w RSTP, or 802.1D STP BPDUs. Regardless of what the “legacy-path-cost”
parameter is set to, MSTP will interoperate with legacy STP bridges (send/receive Config and
TCN BPDUs).
spanning-tree legacy-mode - A “macro” that is the equivalent of executing the “spanning-tree legacy-
path-cost” and “spanning-tree force-version stp-compatible” commands.
no spanning-tree legacy-mode - A “macro” that is the equivalent of executing the “no spanning-tree
legacy-path-cost” and “spanning-tree force-version mstp-compatible” commands.
When either legacy-mode or legacy-path-cost control is toggled, all default path costs will be
recalculated to correspond to the new setting, and spanning tree is recalculated if needed.
QoS Pass-Through Mode
Release M.08.91 introduced a new command that allows the configuration of the Quality of Service
(QoS) queues to be selected. By better matching the configuration of the QoS queues to the amount
of prioritized and non-prioritized traffic being transferred, performance can be improved and packet
loss due to over-subscription can be minimized.
In previous software versions, the 3400cl and the 6400cl switches had four QoS queues of equal size.
Depending on the mix of prioritized and non-prioritized traffic, this configuration might not always
optimize performance and could result in dropped packets when resources were over-subscribed.
Starting with this software version, four QoS Pass-Through modes are available for use. The number
of queues and the size of the memory buffer used by each queue differs in each mode. Table 2 below
summarizes the QoS queue configuration of each mode

routing and spanning tree operation. ProCurve Networking recommends that QoS queues be recon-
figured during periods of non-peak traffic.
Configuring QoS Pass-Through Mode
Syntax: qos-passthrough-mode [ balanced | one-queue | optimized | typical ]
Specifies the QoS queue mode to be used by the switch. The number of queues and the
size of each queue is determined by the mode selected. If no mode is specified theoptimized
mode is used. QoS Pass-Through is disabled using the no qos-pass-through command.
balanced: Configures four QoS queues of the same size. This configuration is the
same as was used by software versions prior to M.08.78.
one-queue: Configures one QoS queue. By consolidating packet buffer memory, line-
rate flows with no loss of data may be achieved.
Note: This mode has a small queue used exclusively by Priority 7 management
and control packets.
optimized: Configures two QoS queues: a small queue for Priority 6 and 7 traffic
and a large queue for all other traffic.
typical: Configures four QoS queues: a large queue for Priority 0 and 3 traffic, and
three other queues for the remaining traffic. This is the default configuration
on the switch and is used when QoS Pass-Through is disabled.
Syntax: [no] qos-passthrough-mode
Specifies the optimized QoS queue mode for the switch.

Added DHCP Option 82 functionality for 3400cl series.
UDP broadcast forwarding feature is now supported on the 3400cl series.
DHCP Option 82: Using the Management VLAN IP Address for the Remote ID
This section describes the Management VLAN enhancement to the DHCP option 82 feature. For more
information on DHCP option 82 operation, refer to “Configuring DHCP Relay” in the chapter titled
“IP Routing Features” in the Advanced Traffic Management Guide.
When the routing switch is used as a DHCP relay agent with Option 82 enabled, it inserts a relay agent
information option into client-originated DHCP packets being forwarded to a DHCP server. The
option automatically includes two suboptions:
■
■
Circuit ID: the identity of the port through which the DHCP request entered the relay agent
Remote ID: the identity (IP address) of the DHCP relay agent
Using earlier software releases, the remote ID can be either the routing switch’s MAC address (the
default option) or the IP address of the VLAN or subnet on which the client DHCP request was
received. Beginning with software release M.08.xx, if a Management VLAN is configured on the
routing switch, then the Management VLAN IP address can be used as the remote ID.

Syntax: dhcp-relay option 82 < append | replace | drop > [ validate ] [ ip | mac | mgmt-vlan ]
[ ip | mac | mgmt-vlan ] : Specifies the remote ID suboption the routing switch will use
in Option 82 fields added or appended to DHCP client packets. The choice depends
on how you want to define DHCP policy areas in the client requests sent to the DHCP
server. If a remote ID suboption is not configured, then the routing switch defaults
to the mac option.
mgmt-vlan: Specifies the IP address of the (optional) Management VLAN configured
on the routing switch. Requires that a Management VLAN is already configured on
the switch. If the Management VLAN is multinetted, then the primary IP address
configured for the Management VLAN is used for the remote ID.
ip: Specifies the IP address of the VLAN on which the client DHCP packet enters the
routing switch. In the case of a multinetted VLAN, the remote ID suboption uses the
IP address of the subnet on which the client request packet is received.
mac: Specifies the routing switch’s MAC address. (The MAC address used is the same
MAC address that is assigned to all VLANs configured on the routing switch.)
(Default: mac)
Example
In the routing switch shown below, option 82 has been configured with mgmt-vlan for the Remote ID.

Operating Notes
■
■
■
Routing is not allowed between the Management VLAN and other VLANs. Thus, a DHCP
server must be available in the Management VLAN if there are clients in the Management
VLAN that require a DHCP server.
If the Management VLAN IP address configuration changes after mgmt-vlan has been config-
ured as the remote ID suboption, the routing switch dynamically adjusts to the new IP
addressing for all future DHCP requests.
The Management VLAN and all other VLANs on the routing switch use the same MAC address.
UDP Broadcast Forwarding
Beginning with software release M.08.94, UDP Broadcast Forwarding is available on the ProCurve
3400cl and 6400cl switches. For further information, refer to the section titled “UDP Broadcast
Forwarding on 5300xl Switches” in the “IP Routing Features” chapter of the Advanced Traffic
Management Guide for your switch. (Note that this manual covers multiple switches and the
description of UDP Broadcast Forwarding is no longer restricted to just the 5300xl switches.)
Some applications rely on client requests sent as limited IP broadcasts addressed to a UDP applica-
tion port. If a server for the application receives such a broadcast, the server can reply to the client.
Since typical router behavior, by default, does not allow broadcast forwarding, a client’s UDP
broadcast requests cannot reach a target server on a different subnet unless the router is configured
to forward client UDP broadcasts to that server.
A switch with routing enabled includes optional per-VLAN UDP broadcast forwarding that allows up
to 256 server and/or subnet entries on the switch (16 entries per-VLAN). If an entry for a particular
UDP port number is configured on a VLAN and an inbound UDP broadcast packet with that port
number is received on the VLAN, then the switch routes the packet to the appropriate subnet. (Each
entry can designate either a single device or a single subnet. The switch ignores any entry that
designates multiple subnets.)

RADIUS-Assigned Access Control Lists (ACLs)
Introducedwithsoftware release M.10.xxonthe 3400clswitches, this feature usesRADIUS-assigned,
per-port ACLs for Layer-3 filtering of inbound IP traffic from authenticated clients. A given RADIUS-
assigned ACL is identified by a unique username/password pair or client MAC address, and applies
only to traffic from clients that authenticate with the same unique credentials. The ACL is applied to
the switch port used by the client and remains in force for the duration of the client session. ACL
services for an authenticated client include filtering inbound IP traffic based on destination and/or
IP traffic type (such as TCP and UDP traffic) and traffic counter options. Implementing the feature
for a given client requires the following:
■
RADIUS authentication of the client must be available on the switch through either 802.1X,
Web authentication, or MAC authentication.
45
Download from Www.Somanuals.com. All Manuals Search And Download.
Enhancements
Release M.10.02 Enhancements
■
An ACL must be configured on the RADIUS server (instead of the switch) by creating and
assigning one or more Access Control Entries to the username/password pair or MAC
address of the client for which you want ACL support.
■
Where 802.1X is used for client authentication, then either the client device must be running
802.1X supplicant software or the capability must exist for the client to download this
software from the network through use of the 802.1X Open VLAN mode available on the
switch. (If authentication is achieved through Web or MAC Authentication, then 802.1X
supplicant software is not required.)
A RADIUS-assigned ACL is a type of extended ACL that filters IP traffic inbound on a port from any
source (and, optionally, of any specific IP application or protocol type) to a single destination IP
address, a group of contiguous IP addresses, an IP subnet, or any IP destination.
This feature is designed to accept dynamic configuration of a RADIUS-based ACL on an individual
port on the network edge to filter traffic from an authenticated end-node client. Using RADIUS to
apply per-port ACLs to edge ports enables the switch to filter IP traffic coming from outside the
network, thus removing unwanted traffic as soon as possible and helping to improve system
performance. Also, applying RADIUS-assigned ACLs to ports on the network edge is likely to be less
complex than using ACLs in the network core to filter unwanted traffic that could have been filtered
at the edge.
This feature enhances network and switch management access security by permitting or denying

This includes preventing clients from using TCP or UDP applications (such as Telnet, SSH, Web

ACLs enhance network security by blocking selected IP traffic, and can serve as one aspect of
network security. However, because ACLs do not protect from malicious manipulation of data carried
in IP packet transmissions, they should not be relied upon for a complete edge security solution.
The ACLs described in this section do not screen non-IP traffic such as AppleTalk and IPX.

supports either one RADIUS-based ACL or one port-based ACL at a time on a given port. It does not
support having both ACL types on the same port at the same time.)

Terminology
ACE: See Access Control Entry, below.
AccessControlEntry(ACE):AnACEisapolicyconsistingofapacket-handlingaction andcriteria
to define the packets on which to apply the action. For RADIUS-based ACLs, the elements
composing the ACE include:
•
permit or drop (action)
•
in < ip-packet-type > from any (source)
to < ip-address [/ mask ] | any > (destination)
•
•
[ port-# ] (optional TCP or UDP application port numbers used when the packet type is TCP
or UDP)
•
[ cnt ] (optional counter that increments when there is a packet match)
ACL: See Access Control List, below.
Access Control List (ACL): A list (or set) consisting of one or more explicitly configured Access
Control Entries (ACEs) and terminating with an implicit “deny” default which drops any packets
that do not have a match with any explicit ACE in the named ACL.
ACL Mask: Follows a destination IP address listed in an ACE. Defines which bits in a packet’s
corresponding IP addressing must exactly match the IP addressing in the ACE, and which bits
need not match (wildcards).
DA: The acronym for Destination IP Address. In an IP packet, this is the destination IP address
carried in the header, and identifies the destination intended by the packet’s originator.
Deny: An ACE configured with this action causes the switch to drop a packet for which there is a
match within an applicable ACL.
Deny Any Any: An abbreviated form of deny in ip from any to any, which denies any inbound IP traffic
from any source to any destination.
Extended ACL: This type of Access Control List uses layer-3 IP criteria composed of source and
destination IP addresses and (optionally) TCP or UDP port criteria to determine whether there
is a match with an IP packet. On the 3400cl switches, the source IP address is always defined as
“any”, and extended ACLs apply only to inbound bridged or routed traffic. For a RADIUS-based,
extended ACL assigned to a port, only the inbound traffic from the client whose authentication
caused the ACL assignment is filtered. Inbound traffic from any other sources is denied.
Implicit Deny:If the switch finds no matches between an inbound packet and the configured criteria
in an applicable ACL, then the switch denies (drops) the packet with an implicit “deny IP any/
any” operation. You can preempt the implicit “deny IP any/any” in a given ACL by configuring
permit in ip from any to any as the last explicit ACE in the ACL. Doing so permits any inbound IP

packet (from the authenticated client) that is not explicitly permitted or denied by other ACEs
configured sequentially earlier in the ACL. Unless otherwise noted, “implicit deny IP any” refers
to the “deny” action enforced by both standard and extended ACLs.
Inbound Traffic:For the purpose of defining where the switch applies ACLs to filter traffic, inbound
traffic is any IP packet that enters the switch from a given client on a given port.
NAS (Network Attached Server): In this context, refers to a ProCurve switch configured for
RADIUS operation.
Permit: An ACE configured with this action allows the switch to forward an inbound packet for
which there is a match within an applicable ACL.
Permit Any Any: An abbreviated form of permit in ip from any to any, which permits any inbound IP
traffic from the authenticated source to any destination. Inbound traffic from any other sources
is denied. (Inbound traffic from a client other than the client whose authentication caused in the
ACL assignment will be denied.)
VSA (Vendor-Specific-Attribute): A value used in a RADIUS-based configuration to uniquely
identify a networking feature that can be applied to a port on a given vendor’s switch during an
authenticated client session.
Wildcard: The part of a mask that indicates the bits in a packet’s IP addressing that do not need to
match the corresponding bits specified in an ACL. See also ACL Mask on page 48.
Caution Regarding the Use of Source Routing
Source routing is enabled by default on the switch and can be used to override ACLs. For this reason,
if you are using ACLs to enhance network security, the recommended action is to use the no ip source-
route command to disable source routing on the switch. (If source routing is disabled in the running-
config file, the show running command includes “no ip source-route” in the running-config file listing.)
General Operation
An ACL is a list of one or more Access Control Entries (ACEs), where each ACE consists of a matching
criteria and an action (permit or deny). These ACEs are designed to control the network access
privileges of an authenticated client. A RADIUS-based ACL applies only to the inbound traffic from
the client whose authentication triggers the ACL assignment to the client port.
How a RADIUS Server Applies a RADIUS-Based ACL to a Switch Port. A RADIUS-based
ACL configured on a RADIUS server is identified and invoked by the unique credentials (username/
password pair or a client MAC address) of the specific client the ACL is designed to service. Where
the username/password pair is the selection criteria, the corresponding ACL can also be used for a
groupofclients that all requirethe sameACLpolicyand use thesame username/passwordpair. Where
49

Enhancements
Release M.10.02 Enhancements
the client MAC address is the selection criteria, only the client having that MAC address can use the
corresponding ACL. When a RADIUS server authenticates a client, it also assigns the ACL configured
with that client’s credentials to the port. The ACL then filters the client’s inbound IP traffic and denies
(drops) any such traffic from the client that is not explicitly permitted by the ACL. (Every ACL ends
with an implicit deny in ip from any to any (“deny any any”) ACE that denies IP traffic not specifically
permitted by the ACL.) When the client session ends, the switch removes the RADIUS-based ACL
from the client port.
When multiple clients supported by the same RADIUS server use the same credentials, they will all
be serviced by different instances of the same ACL. (The actual traffic inbound from any client on
the switch carries a source MAC address unique to that client. The RADIUS-based ACL uses this MAC
address to identify the traffic to be filtered.)
Notes
On any ACL assigned to a port, there is an implicit deny in ip from any to any (“deny any any”) command
that results in a default action to deny any inbound IP traffic that is not specifically permitted by the
ACL. To reverse this default, use an explicit “permit any” as the last ACE in the ACL.
On a given port, RADIUS-based ACL filtering occurs only for the inbound traffic from the client whose
authentication caused a RADIUS-based ACL assignment. Inbound traffic from any other source,
including a second, authenticated client (on the same port) will be denied.
The Packet-filtering Process
Sequential Comparison and Action. When an ACL filters a packet from an authenticated client,
it sequentially compares each ACE’s filtering criteria to the corresponding data in the packet until it
finds a match. The action indicated by the matching ACE (deny or permit) is then performed on the
packet.
Implicit Deny. If a packet from the authenticated client does not have a match with the criteria in
any of the ACEs in the ACL, the ACL denies (drops) the packet. If you need to override the implicit
deny so that a packet (from the authenticated client) that does not have a match will be permitted,
then you can use the “permit any” option as the last ACE in the ACL. This directs the ACL to permit
(forward) packets that do not have a match with any earlier ACE listed in the ACL, and prevents
these packets from being filtered by the implicit “deny any”. (Note that the “permit any” option applies
only to packets from the client whose authentication caused the assignment of the ACL to the port.)

1. Compares the packet to this ACE first.
2. Since there is not a match with the first
ACE, the ACL compares the packet to the
second ACE, where there is also not a
match.
(Deny in ip from any to any)
3. The ACL compares the packet to the third
ACE. There is an exact match, so the ACL
denies (drops) the packet.
This line demonstrates the “deny any any” ACE implicit in every
RADIUS-based ACL. Any inbound ip traffic from the authenticated
client that does not have a match with any of the five explicit ACEs
in this ACL will be denied by the implicit “deny any any”.
4. The packet is not compared to the fourth
ACE.
Figure 3. Example of Sequential Comparison
As shown above, the ACL tries to apply the first ACE in the list. If there is not a match, it tries the
second ACE, and so on. When a match is found, the ACL invokes the configured action for that entry
(permit or drop the packet) and no further comparisons of the packet are made with the remaining
ACEs in the list. This means that when an ACE whose criteria matches a packet is found, the action
configured for that ACE is invoked, and any remaining ACEs in the ACL are ignored. Because of this
sequential processing, successfully implementing an ACL depends in part on configuring ACEs
in the correct order for the overall policy you want the ACL to enforce.
Note
Because only one ACL is allowed on a port, if a statically configured ACL already exists on a port, a
RADIUS-based ACL cannot be assigned to that port. In this case, if a client authenticates and the
RADIUS server is configured to assign a dynamic ACL to the port for that client, the client will then
be de-authenticated.

The order in which an ACE occurs in an ACL is significant. For example, if an ACL contains six ACEs,

and the remaining ACEs in the list do not apply, even if they specify criteria that would make a match
with any of the traffic permitted by the first ACE.

For example, suppose you want to configure a RADIUS-based ACL to invoke these policies in the
11.11.11.0 network:
1. Permit inbound client traffic with a DA of 11.11.11.42.
2. Permit inbound Telnet traffic for DA 11.11.11.101.

General Steps
These steps suggest a process for using ACLs to establish client access policies. The topics following
this section provide details.
1. Determine the polices you want to enforce for client traffic inbound on the switch.
2. Plan ACLs to execute traffic policies:
•
Apply ACLs on a per-client basis where individual clients need different traffic policies
or where each client must have a different username/password pair or will authenticate
using MAC authentication.
•
Apply ACLs on a client group basis where all clients in a given group can use the same
traffic policy and the same username/password pair.
3. Configure the ACLs on a RADIUS server accessible to the intended clients.
4. Configure the switch to use the desired RADIUS server and to support the desired client
authentication scheme. Options include 802.1X, Web authentication, or MAC authentication.
(Note that the switch supports the option of simultaneously using 802.1X with either Web or
MAC authentication.)
5. Test client access on the network to ensure that your RADIUS-based ACL application is properly
enforcing your policies.
Determining Traffic Policies
This section assumes that the RADIUS server needed by a client for authentication and ACL
assignments is accessible from any switch that authorized clients may use.
Begin by defining the policies you want an ACL to enforce for a given client or group of clients. This
includes the type of IP traffic permitted or not permitted from the client(s) and the areas of the
network the client(s) are authorized or not authorized to use.
■
Whattrafficshouldyoupermitfortheclient?In somecasesyouwillneed toexplicitly identify
permitted traffic. In other cases, depending on your policies, you can insert a permit in ip from
any to any entry at the end of the ACL so that all IP traffic (from the authenticated client) that
is not specifically matched by earlier entries in the list will be permitted. This may be the
best choice for an ACL that begins by defining the inbound client IP traffic that should be
dropped.
■
■
What traffic must be explicitly blocked for the client or group? This can include requests to
access to “off-limits” subnets, unauthorized access to the internet, access to sensitive data
storage or restricted equipment, and preventing the use of specific TCP or UDP applications
such as Telnet, SSH, and web browser access to the switch.
What traffic can be blocked simply by relying on the implicit deny in ip from any to any that is
automatically included at the end of every ACL? This can reduce the number of entries
needed in an ACL.

■
Is it important to keep track of the number of matches for a particular client or ACE? If so,
you can use the optional cnt (counter) feature in ACEs where you want to know this
information. This is especially useful if you want to verify that the switch is denying
unwanted client packets. (Note that configuring a high number of counters can exhaust the
counter resources. Refer to Table 5 on page 57.)
Caution
ACLs can enhance network security by blocking selected IP traffic, and can serve as one aspect of
maintaining network security. However, because ACLs do not provide user or device authentication,
orprotectionfrommaliciousmanipulationofdatacarriedinIPpackettransmissions, theyshould
not be relied upon for a complete security solution.
Planning the ACLs Needed To Enforce Traffic Policies
This section can help in understanding how to order the ACEs in a RADIUS-based ACL and in
understanding how clients and the switch operate in this dynamic environment.
Guidelines for Structuring a RADIUS-Based ACL.
■
The sequence of ACEs is significant. When the switch uses an ACL to determine whether to
permit or deny a packet on a particular port, it compares the packet to the criteria specified
in the individual Access Control Entries (ACEs) in the ACL, beginning with the first ACE in
the list and proceeding sequentially until a match is found. When a match is found, the switch
applies the indicated action (permit or deny) to the packet. This is significant because, when
a match is found for a packet, subsequent ACEs in the same ACL will not be used for that
packet, regardless of whether they match the packet.
■
Inbound Traffic Only: RADIUS-based ACLs filter only the inbound IP traffic from an
authenticated client for which an ACL has been configured on the appropriate RADIUS
server.
■
■
Result of an ACE/Packet Match: The first match of a given packet to an ACE dictates the
action for that packet. Any subsequent match possibilities are ignored.
Explicitly Permitting Any IP Traffic from the Authenticated Client: Entering a permit
in ip from any to any (permit any any) ACE in a RADIUS-based ACL permits all IP traffic (from
the authenticated client) that is not previously permitted or denied by that ACL. Any ACEs
listed after that point do not have any effect. (While a RADIUS-based ACL is applied to a
port, traffic inbound from sources other than the client whose authentication caused the
ACL assignment is denied.)

Enhancements
Release M.10.02 Enhancements
■
Explicitly Denying Any IP Traffic: Entering a deny in ip from any to any ACE in an ACL
denies all IP traffic not previously permitted or denied by that ACL. Any ACEs listed after
that point have no effect.
■
Implicitly Denying Any IP Traffic: For any packet being filtered by an ACL, there will
always be a match. Included in every ACL is an implicit deny in ip from any to any. This means
that the ACL denies any IP packet it filters that does not have a match with an explicitly
configured ACE. Thus, if you want an ACL to permit any packets that are not explicitly
denied, you must configure permit in ip from any to any as the last explicit ACE in the ACL.
Because, for a given packet, the switch sequentially applies the ACEs in an ACL until it finds
a match, any packet that reaches the permit in ip from any to any entry will be permitted, and
will not reach the implicit deny in ip from any to any ACE that is included at the end of the ACL.
For an example, refer to Figure 5 on page 53.
■
Determine the order in which you want the individual ACEs in the ACL to filter inbound
traffic from a client. A general guideline is to arrange the ACEs in the expected order of
decreasing application frequency. This will result in the most prevalent traffic types finding
a match earlier in the ACL than traffic types that are more infrequent, thus saving processing
cycles.
Operating Rules for RADIUS-Based ACLs
■
■
■
ACL Assignments Per-Port: One RADIUS-assigned ACL is allowed per-port.
Port Trunks Excluded: RADIUS-assigned ACLs cannot be assigned to a port trunk.
Relating a Client to a RADIUS-Based ACL: A RADIUS-based ACL for a particular client
must be configured in the RADIUS server under the authentication credentials the server
should expect for that client. (If the client must authenticate using 802.1X and/or Web
Authentication, the username/password pair forms the credential set. If authentication is
through MAC Authentication, then the client MAC address forms the credential set.) For
more on this topic, refer to “Configuring an ACL in a RADIUS Server” on page 58.
■
■
Multiple Clients Using the Same Username/Password Pair: Multiple clients using the
same username\password pair will use duplicate instances of the same ACL.
RADIUS-Based ACL Not Allowed on a Port that has a Statically-Configured ACL:
Where a RADIUS server is configured to assign an ACL when a given client authenticates, if
the port used by that client is already statically configured with a port-based ACL in the
switch configuration, then the RADIUS-based ACL is not accepted and the client is de-
authenticated.
■
A RADIUS-Based ACL Affects Only the Inbound Traffic from a Specific, Authenti-
cated Client:A RADIUS-based ACL assigned to a port as the result of a client authenticating
on that port applies only to the inbound traffic received on that port from that client. It does
not affect the traffic received from any other authenticated clients on that port, and does not
affect any outbound traffic on that port.

Elements in a RADIUS-Based ACL Configuration. A RADIUS-based ACL configuration in a
RADIUS server has the following elements:
■
vendor and ACL identifiers:
•
•
•
ProCurve (HP) Vendor-Specific ID: 11
Vendor-Specific Attribute for ACLs: 61 (string = HP-IP-FILTER-RAW)
Setting: HP-IP-FILTER-RAW = < “permit” or “deny” ACE >
(Note that the “string” value and the “Setting” specifier are identical.)
ACL configuration, including:
■
•
•
one or more explicit “permit” and/or “deny” ACEs created by the system operator
implicit deny in ip from any to any ACE automatically active after the last operator-created
ACE
■
ACEs define the ACL for a given client:
•
A given ACE configuration on a RADIUS server includes the identity of the client to
which it applies. That is, the ACE includes the client username/password pair or the
client device’s MAC address.
•
All ACEs configured on a RADIUS server for the same client are interpreted as belonging
to the same ACL. (There is no ACL name or number configured on the RADIUS server.)
Example of Configuring a RADIUS-based ACL Using the FreeRADIUS Application. This
example illustrates one method for configuring RADIUS-based ACL support for two different client
identification methods (username/password and MAC address). For information on how to configure
this functionality on other RADIUS server types, refer to the documentation provided with the server.

you would enter the following in the server’s clients.conf file:
client 10.10.10.125
Note: The key configured in the switch and the secret configured in
nastype = other
secret = 1234
the RADIUS server supporting the switch must be identical. Refer to
the chapter titled “RADIUS Authentication and Accounting” in the
Access Security Guide for your switch.
Figure 7. Example of Configuring the Switch’s Identity Information in a FreeRADIUS Server
3. For a given client username/password pair or MAC address, create an ACL by entering one or
more ACEs in the FreeRADIUS “users” file. Enter the ACEs in an order that promotes optimum
traffic management and conservation of system resources, and remember that every ACL you
create automatically includes an implicit deny in ip from any to any ACE. (Refer to “Guidelines for
Structuring a RADIUS-Based ACL” on page 55.) For example, suppose that you wanted to create
identical ACL support for the following:
•
•
a client having a username of “mobile011” and a password of “run101112”
a client having a MAC address of 08 E9 9C 4F 00 19
The ACL in this example must achieve the following:
•
•
•
permit http (TCP port 80) traffic from the client to the device at 10.10.10.101
deny http (TCP port 80) traffic from the client to all other devices
permit all other traffic from the client to all other devices
To configure the above ACL, you would enter the username/password and ACE information
shown in Figure 8 into the FreeRADIUS users file.

Any instance of a RADIUS-Based ACL is structured to filter authenticated client traffic as follows:
■
■
■
Applies only to inbound client traffic on the switch port the authenticated client is using.
Allows only the “any” source address (for any authenticated IP device connected to the port).
Applies to all IP traffic from the authenticated client or to a specific type of IP traffic type
from the client. Options include TCP, UDP, or any other type of IP traffic that is identified by
an IP protocol number. (More information on protocol numbers is provided in the following
ACL syntax description.)
■
Has one of the following destination types:
•
•
•
A specific IP address
A contiguous series of IP address or an entire subnet
Any IP address
■
Where the traffic type is either TCP or UDP, the ACE can optionally include one or more TCP
or UDP port numbers.

The following syntax and operating information refers to ACLs configured in a RADIUS server
.
ACE Syntax: < permit | deny > in < ip | ip-protocol-value > from any to < ip-addr > [/< mask > ] | any > [ tcp/udp-ports] [cnt ]
< permit | deny >: Specifies whether to forward or drop the identified IP traffic type from the
authenticated client.
in: Required keyword specifying that the ACL applies only to the traffic inbound from the
authenticated client.
< ip | ip-protocol-value >: Options for specifying the type of traffic to filter.
ip: This option applies the ACL to all IP traffic from the authenticated client.
ip-protocol-value: This option applies the ACL to the type of IP traffic specified by either
a protocol number or by tcp or udp. The range of protocol numbers is 0-255, and you
can substitute 6 for TCP or 17 for UDP. (Protocol numbers are defined in RFC 2780.
For a complete listing, refer to “Protocol Numbers” under “Protocol Number Assign-
ment Services” on the Web site of the Internet Assigned Numbers Authority at
www.iana.com.) Some examples of protocol numbers include:
1 = ICMP
2 = IGMP
6 = TCP
17 = UDP
41 = IPv6
from any: Required keywords specifying the (authenticated) client source. (Note that a
RADIUS-Based ACL assigned to a port filters only the inbound traffic having a source
MAC address that matches the MAC address of the client whose authentication invoked the
ACL assignment.)
to : Required destination keyword.
< ip-addr >: Specifies a single destination IP address.
< ip-addr /< mask >: Specifies a series of contiguous destination IP addresses or all
destination IP addresses in a subnet. The < mask > is CIDR notation for the number
of leftmost bits in a packet’s destination IP address that must match the corre-
sponding bits in the destination IP address listed in the ACE. For example, a
destination of 10.100.17.1/24 in the ACE means that a match occurs when an
inbound packet (of the designated IP type) from the authenticated client has a
destination IP address where the first three octets are 10.100.17. (The fourth octet is
a wildcard, and can be any value up to 255.)
any: Specifies any IP destination address. Use this option when you want the ACL
action to apply to all traffic of the designated type, regardless of destination.
[ tcp/udp-ports]: Optional TCP or UDP port specifier. Used when the ACL is intended to filter
client TCP or UDP traffic with one or more specific TCP or UDP destination port numbers.
You can specify port numbers as individual values and/or ranges. For example, the
following ACE denies any UDP traffic from an authenticated client that has a DA of any
IP address and a UDP destination port of 135, 137-139, or 445:
deny in udp from any to any 135, 137-139, 445.

[ cnt ]: Optional counter specifier for a RADIUS-based ACL. When used in an ACL, the
counter increments each time there is a “match” with a permit or deny ACE. (Refer to the
entry describing the maximum number of (optional) internal counters in the table on
page 57.) Counter values appear in RADIUS accounting log for client if RADIUS
networking accounting is configured on the switch.
Configuring the Switch To Support RADIUS-Based ACLs
An ACL configured in a RADIUS server is identified by the authentication credentials of the client or
group of clients the ACL is designed to support. When a client authenticates with credentials
associated with a particular ACL, the switch applies that ACL to the switch port the client is using.
To enable the switch to forward a client’s credentials to the RADIUS server, you must first configure
RADIUS operation and an authentication method on the switch.
1. Configure RADIUS operation on the switch:
Syntax: radius-server host < ip-address > key < key-string >
[auth-port < udp-dest-port > acct-port < udp-dest-port >]
This command configures the IP address and encryption key of a RADIUS server. The server
should be accessible to the switch and configured to support authentication requests from
clients using the switch to access the network. For more on RADIUS configuration, including
the auth-port and acct-port options, refer to the chapter titled “RADIUS Authentication and
Accounting” in the Access Security Guide for your switch.
2. Configure RADIUS network accounting on the switch (optional). RADIUS network accounting
is necessary to retrieve counter information if the cnt (counter) option (described on page 62)
is included in any of the ACEs configured on the RADIUS server.
Syntax: aaa accounting network < start-stop | stop-only > radius
For more on RADIUS accounting, refer to the chapter titled “RADIUS Authentication and
Accounting” in the Access Security Guide for your switch.
Note
Refer to the documentation provided with your RADIUS server for information on how the server
receives and manages network accounting information, and how to perform any configuration
steps necessary to enable the server to support network accounting data from the switch.

3. Configure an authentication method. Options include 802.1X, Web authentication, and MAC
authentication. (You can configure 802.1X and either Web or MAC authentication to operate
simultaneously on the same ports.)
802.1X Option:
Syntax: aaa port-access authenticator < port-list >
aaa authentication port-access chap-radius
aaa port-access authenticator active
These commands configure 802.1X port-based access control on the switch, and activates
this feature on the specified ports. For more on 802.1X configuration and operation, refer to
the chapter titled “Configuring Port-Based and Client-Based Access Control” in the Access
Security Guide for your switch.
MAC Authentication Option:
Syntax: aaa port-access mac-based < port-list >
This command configures MAC authentication on the switch and activates this feature on
the specified ports. For more on MAC authentication, refer to the chapter titled “Web and
MAC Authentication” in the Access Security Guide for your switch.
Web Authentication Option:
Syntax: aaa port-access web-based < port-list >
This command configures Web authentication on the switch and activates this feature on the
specified ports. For more on Web authentication, refer to the chapter titled “Web and MAC
Authentication” in the Access Security Guide for your switch.

Displaying the Current RADIUS-Based ACL Activity on the Switch
These commands output data indicating the current ACL activity imposed per-port by RADIUS server
responses to client authentication.
Syntax: show access-list radius < port-list >
For the specified ports, this command lists the explicit ACEs, switch port, and client MAC
address for the ACL dynamically assigned by a RADIUS server as a response to client
authentication. If cnt (counter) is included in an ACE, then the output includes the current
number of inbound packet matches the switch has detected in the current session for that
ACE.
Note: If there are no ACLs currently assigned to any port in < port-list >, executing this
command returns the following message:
Port < port-# >, No RADIUS ACLs applied on this port.
If a client authenticates but the server does not return a RADIUS-based ACL to the client
port, then the server does not have a valid ACL configured and assigned to that client’s
authentication credentials.
For example, the following output shows that a RADIUS server has assigned an ACL to port 10 to
filter inbound traffic from an authenticated client identified by a MAC address of 00-11-85-C6-54-7D.

SFlow Show Commands
In earlier software releases, the only method for checking whether sFlow is enabled on the switch
was via an snmp request. Beginning with software release M.10.02, the 3400cl switches have added
the following show sFlow commands that allow you to see sFlow status via the CLI.
Syntax: show sflow agent
Displays sFlow agent information. The agent address is normally the ip address of
the first vlan configured.
Syntax: show sflow destination
Displays information about the management station to which the sFlow sampling-
polling data is sent.
Syntax: show sflow sampling-polling <port-list/range>
Displays status information about sFlow sampling and polling.
Syntax: show sflow all
Displays sFlow agent, destination, and sampling-polling status information for all
the ports on the switch.
Terminology
sFlow — An industry standard sampling technology, defined by RFC 3176, used to continuously
monitor traffic flows on all ports providing network-wide visibility into the use of the network.
sFlow agent — A software process that runs as part of the network management software within a
device. The agent packages data into datagrams that are forwarded to a central data collector.
sFlow destination — The central data collector that gathers datagrams from sFlow-enabled switch
ports on the network. The data collector decodes the packet headers and other information to
present detailed Layer 2 to Layer 7 usage statistics.
Viewing SFlow Configuration
The show sflow agent command displays read-only switch agent information. The version information
shows the sFlow MIB support and software versions; the agent address is typically the ip address of
the first vlan configured on the switch.

(DoS) logging enhancement.
■
■
Enhancement (PR_1000331027) - TCP/UDP port closure enhancement.

Instrumentation Monitor
The 3400cl switches have instrumentation to monitor many operating parameters at pre-determined
intervals. Beginning with software release M.10.04, this capability can be used to detect anomalies
caused by security attacks or other irregular operations on the switch. The following table shows the
parameters that can be monitored, and the possible security attacks that may trigger an alert:
Parameter Name
Description
pkts-to-closed-ports
The count of packets per minute sent to closed TCP/UDP ports. An excessive amount
of packets could indicate a port scan, in which an attacker is attempting to expose a
vulnerability in the switch.
arp-requests
The count of ARP requests processed per minute. A large amount of ARP request
packets could indicate an host infected with a virus that is trying to spead itself.

Enhancements
Release M.10.04 Enhancements
Parameter Name
Description
ip-address-count
The number of destination IP addresses learned in the IP forwarding table. Some
attacks fill the IP forwarding table causing legitimate traffic to be dropped.
system-resource-usage
(Denial of Service logging)
The percentage of system resources in use. Some Denial-of-Service (DoS) attacks
will cause excessive system resource usage, resulting in insufficient resources for
legitimate traffic.
login-failures/min
The count of failed CLI login attempts or SNMP management authentication failures.
This indicates an attempt has been made to manage the switch with an invalid login
or password. Also, it might indicate a network management station has not been
configured with the correct SNMP authentication parameters for the switch.
port-auth-failures/min
system-delay
The count of times a client has been unsuccessful logging into the network
The response time, in seconds, of the CPU to new network events such as BPDU
packets or packets for other network protocols. Some DoS attacks can cause the
CPU to take too long to respond to new network events, which can lead to a
breakdown of Spanning Tree or other features. A delay of several seconds indicates
a problem.
mac-address-count
mac-moves/min
The number of MAC addresses learned in the forwarding table. Some attacks fill the
forwarding table so that new conversations are flooded to all parts of the network.
The average number of MAC address moves from one port to another per minute.
This usually indicates a network loop, but can also be caused by DoS attacks.
learn-discards/min
Number of MAC address learn events per minute discarded to help free CPU
resources when busy.
Operating Notes
■
To generate alerts for monitored events, you must enable the instrumentation monitoring
log and/or SNMP trap. The threshold for each monitored parameter is configurable and can
be adjusted to minimize false alarms (see “Configuring Instrumentation Monitor” onpage 73).
■
When a parameter exceeds its threshold, an alert (event log message and/or SNMP trap) is

W 01/01/90 00:20:00 inst-mon: Ceasing logs for MAC addr count for 15 minutes
Figure 17. Example of the rate limiting that occurs when multiple messages are generated
In the preceding example, if a condition is reported 4 times (persists for more than 15 minutes)
then alerts cease for 15 minutes. If after 15 minutes the condition still exists, the alerts cease for
30 minutes, then for 1 hour, 2 hours, 4 hours, 8 hours, and after that the persisting condition is
reported once a day. Note that ProCurve switches also have the ability to send event log entries
to a syslog server.
Known Limitations
As of release M.10.06, the instrumentation monitor runs once every five minutes. The current
implementation does not track information such as the port, MAC, and IP address from which an
attack is received.

TCP/UDP Port Closure
In earlier software releases, certain UDP ports were always open. Beginning with software release
M.10.04, all TCP/UDP ports on the 3400cl switches will remain closed until the associated services
are enabled on the switch.
The following ports and services are affected by this change:
Port
69
Service
TFTP
161
520
1507
SNMP
RIP
Stacking (SNMP)
To open any of these ports, the respective services must first be enabled on the switch. For
information on how to enable/disable these services, refer to the following command listings . For
details on each service, refer to the latest version of the switch’s software documentation available
on the ProCurve Networking Web site.

■
TC refers to a Topology Change detected on the given port. Note the following details:
•
TC Detected counter shows when a port identifies a topology change (increments when
the particular non-Edge port goes into forwarding). For RSTP and MSTP, this would be
due to the switch’s link going to forwarding.
•
TC Flag Transmitted counter shows the number of TC notifications sent out of the port.
This refers to propagating a topology change that occurred on another port (that is, a
TC Detected increment) or to propagating a topology change received on another port
(that is, TC Flag Received).

Uni-Directional Link Detection (UDLD)
Uni-directional Link Detection (UDLD) monitors a link between two ProCurve switches and blocks
the ports on both ends of the link if the link fails at any point between the two devices. This feature
is particularly useful for detecting failures in fiber links and trunks.
In the example shown in Figure 20, each ProCurve switch load balances traffic across two ports in
a trunk group. Without the UDLD feature, a link failure on a link that is not directly attached to one
of the ProCurve switches remains undetected. As a result, each switch continues to send traffic on
the ports connected to the failed link. When UDLD is enabled on the trunk ports on each ProCurve
switch, the switches detect the failed link, block the ports connected to the failed link, and use the
remaining ports in the trunk group to forward the traffic.

Enhancements
Release M.10.09 Enhancements
Scenario 1 (No UDLD): Without UDLD, the switch ports
remain enabled despite the link failure. Traffic continues to
be load-balanced to the ports connected to the failed link.
Scenario 2 (UDLD-enabled): When UDLD is enabled, the
feature blocks the ports connected to the failed link.

Figure 20. UDLD Example
Similarly, UDLD is effective for monitoring fiber optic links that use two uni-direction fibers to
transmit and receive packets. Without UDLD, if a fiber breaks in one direction, a fiber port may
assume the link is still good (because the other direction is operating normally) and continue to send
traffic on the connected ports. UDLD-enabled ports, however, prevent traffic from being sent across
a bad link by blocking the ports in the event that either the individual transmitter or receiver for that
connection fails.
Ports enabled for UDLD exchange health-check packets once every five seconds (the link-keepalive
interval). If a port does not receive a health-check packet from the port at the other end of the link
within the keepalive interval, the port waits for four more intervals. If the port still does not receive
a health-check packet after waiting for five intervals, the port concludes that the link has failed and
blocks the UDLD-enabled port.
When a port is blocked by UDLD, the event is recorded in the switch log or via an SNMP trap (if
configured); and other port blocking protocols, like spanning tree or meshing, will not use the bad
link to load balance packets. The port remains blocked until the link is unplugged, disabled, or fixed.
The port can also be unblocked by disabling UDLD on the port.

Configuration Considerations
■
UDLD is configured on a per-port basis and must be enabled at both ends of the link. See the
note below for a list of ProCurve switches that support UDLD.
■
To configure UDLD on a trunk group, you must configure the feature on each port of the
group individually. Configuring UDLD on a trunk group’s primary port enables the feature
on that port only.
■
Dynamic trunking is not supported. If you want to configure a trunk group that contains
ports on which UDLD is enabled, you must remove the UDLD configuration from the ports.
After you create the trunk group, you can re-add the UDLD configuration.
Note
UDLD interoperates with the following ProCurve switch series: 2600, 2800, 3400, 3500, 4200, 5300,
5400, 6200, 6400, and 9300. Consult the release notes and current manuals for required software
versions.
Configuring UDLD
The following commands allow you to configure UDLD via the CLI.
Syntax: [no] interface <port-list> link-keepalive
Enables UDLD on a port or range of ports.
To disable the feature, enter the no form of the command.
Default: UDLD disabled
Syntax: link-keepalive interval <interval>
Determines the time interval to send UDLD control packets. The <interval> param-
eter specifies how often the ports send a UDLD packet. You can specify from 10 –
100, in 100 ms increments, where 10 is 1 second, 11 is 1.1 seconds, and so on.
Default: 50 (5 seconds)
Syntax: link-keepalive retries <num>
Determines the maximum number of retries to send UDLD control packets. The
<num>parameterspecifiesthemaximumnumber oftimestheportwilltrythehealth
check. You can specify a value from 3 – 10.
Default: 5
Syntax: [no] interface <port-list> link-keepalive vlan <vid>
Assigns a VLAN ID to a UDLD-enabled port for sending of tagged UDLD control
packets.Under default settings, untagged UDLD packets can still be transmitted and
received on tagged only ports—however, a warning message will be logged.
The no form of the command disables UDLD on the specified port(s).
Default: UDLD packets are untagged; tagged only ports will transmit and receive
untagged UDLD control packets

Enhancements
Release M.10.09 Enhancements
Enabling UDLD. UDLD is enabled on a per port basis. For example, to enable UDLD on port a1,
enter:
ProCurve(config)#interface al link-keepalive
To enable the feature on a trunk group, enter the appropriate port range. For example:
ProCurve(config)#interface al-a4 link-keepalive
Note
When at least one port is UDLD-enabled, the switch will forward out UDLD packets that arrive on
non-UDLD-configured ports out of all other non-UDLD-configured ports in the same vlan. That is,
UDLD control packets will “pass through” a port that is not configured for UDLD. However, UDLD
packets will be dropped on any blocked ports that are not configured for UDLD.
Changing the Keepalive Interval. By default, ports enabled for UDLD send a link health-check
packet once every 5 seconds. You can change the interval to a value from 10 – 100 deciseconds,
where 10 is 1 second, 11 is 1.1 seconds, and so on. For example, to change the packet interval to
seven seconds, enter the following command at the global configuration level:
ProCurve(config)# link-keepalive interval 70
Changing the Keepalive Retries. By default, a port waits five seconds to receive a health-check
reply packet from the port at the other end of the link. If the port does not receive a reply, the port
tries four more times by sending up to four more health-check packets. If the port still does not
receive a reply after the maximum number of retries, the port goes down.
You can change the maximum number of keepalive attempts to a value from 3 – 10. For example, to
change the maximum number of attempts to 4, enter the following command at the global configu-
ration level:
ProCurve(config)# link-keepalive retries 4
Configuring UDLD for Tagged Ports. The default implementation of UDLD sends the UDLD
control packets untagged, even across tagged ports. If an untagged UDLD packet is received by a
non-ProCurve switch, that switch may reject the packet. To avoid such an occurrence, you can
configure ports to send out UDLD control packets that are tagged with a specified VLAN.
To enable ports to receive and send UDLD control packets tagged with a specific VLAN ID, enter a
command such as the following at the interface configuration level:
ProCurve(config)#interface l link-keepalive vlan 22

Notes
■
■
■
■
You must configure the same VLANs that will be used for UDLD on all devices across the
network; otherwise, the UDLD link cannot be maintained.
If a VLAN ID is not specified, then UDLD control packets are sent out of the port as untagged
packets.
To re-assign a VLAN ID, re-enter the command with the new VLAN ID number. The new
command will overwrite the previous command setting.
When configuring UDLD for tagged ports, you may receive a warning message if there are
any inconsistencies with the port’s VLAN configuration (see page 87 for potential problems).

Release M.10.10 Enhancements
Release M.10.10 includes the following enhancement:
Spanning Tree Per-Port BPDU Filtering
The STP BPDU filter feature allows control of spanning-tree participation on a per-port basis. It can
be used to exclude specific ports from becoming part of spanning tree operations. A port with the
BPDU filter enabled will ignore incoming BPDU packets and stay locked in the spanning-tree
forwarding state. All other ports will maintain their role.
Here are some sample scenarios in which this feature may be used:
■
To have STP operations running on selected ports of the switch rather than every port of the
switch at a time.
■
■
To prevent the spread of errant BPDU frames.
To eliminate the need for a topology change when a port's link status changes. For example,
ports that connect to servers and workstations can be configured to remain outside of
standard spanning-tree operations.
■
To protect the network from denial of service attacks with spoofing spanning-tree BPDUs
by dropping incoming BPDU frames.
Note
BPDU protection imposes a more secure mechanism that implements port shut down and a detection
alert when an errant BPDU frame is received ( see page 91 for details). BPDU protection will take
precedence over BPDU filtering if both features have been enabled on the same port.
Configuring STP BPDU Filters
The following commands allow you to configure BPDU filters via the CLI.
Syntax: [no] spanning-tree <port-list | all> bpdu-filter
Enables/disables the BPDU filter feature on the specified port(s).
For example, to configure BPDU filtering on port a9, enter:
ProCurve(config)# spanning-tree a9 bpdu-filter

Enhancements
Release M.10.10 Enhancements
Caution
Ports configured with the BPDU filter mode remain active (learning and forward frames); however,
spanning-tree cannot receive or transmit BPDUs on the port. The port remains in a forwarding state,
permitting all broadcast traffic. This can create a network storm if there are any loops (that is, trunks
or redundant links) using these ports. If you suddenly have a high load, disconnect the link and
remove ("no") the bpdu-filter.

Spanning Tree BPDU Protection
The BPDU protection feature is a security enhancement to Spanning Tree Protocol (STP) operation.
Itcanbe usedtoprotecttheactive STP topologybydelimiting itslegal boundaries, thereby preventing
spoofed BPDU packets from entering the STP domain. In a typical implementation, BPDU protection
would be applied to edge ports connected to end user devices that do not run STP. If STP BPDU
packets are received on a protected port, the feature will disable that port and alert the network
manager via an SNMP trap as shown in Figure 27.

Terminology
BPDU — Acronym for bridge protocol data unit. BPDUs are data messages that are exchanged
between the switches within an extended LAN that use a spanning tree protocol topology. BPDU
packets contain information on ports, addresses, priorities and costs and ensure that the data ends
up where it was intended to go. BPDU messages are exchanged across bridges to detect loops in a
network topology. The loops are then removed by placing redundant switch ports in a backup, or
blocked, state.
BPDU Filtering — Spanning-tree configuration mode that prevents the switch from receiving and
transmitting BPDU frames on a specific port.
BPDU Protection — Spanning-tree configuration mode which disables a port where BPDU frames
are received.
MSTP — Multiple Spanning Tree Protocol, defined in IEEE 802.1s. Each MSTI (multiple spanning
tree instance) on a physical port provides loop free connectivity for the group of VLANs associated
with that instance. This means that traffic transported on different VLANs can be distributed for load-
balancing among links between switches.
RSTP — Rapid Spanning Tree Protocol, defined in IEEE 802.1w and ratified in IEEE 802.1D-2004.
Spanning-tree — Generic term to refer to the many spanning-tree flavors: now deprecated STP,
RSTP and VLAN-aware MSTP.

Enhancements
Release M.10.17 Enhancements
STP — Spanning Tree Protocol, part of the original IEEE 802.1D specification. The 2004 edition
completely deprecates STP. Both RSTP and MSTP have fallback modes to handle STP.
SNMP — Simple Network Management Protocol, used to remotely manage network devices.
Note
The switches covered in these Release Notes, use the IEEE 802.1s Multiple Spanning Tree Protocol
(MSTP) standard. Under standard settings, your MSTP-configured switch interoperates effectively
with both STP (IEEE 802.1D) and RSTP (IEEE 802.1w) spanning-tree devices. For more information,
refer to the chapter entitled Multiple Instance Spanning-Tree Operation in the Advanced Traffic
Management Guide for your switch.
Configuring STP BPDU Protection
The following commands allow you to configure BPDU protection via the CLI.
Syntax: [no] spanning-tree <port-list> bpdu protection
Enables/disables the BPDU protection feature on a port
Syntax: [no] spanning-tree trap errant bpdu
Enables/disables the sending of errant BPDU traps.
For example, to configure BPDU protection on ports 1 to 10, enter:
ProCurve(config)# spanning-tree 1-10 bpdu protection
When BPDU protection is enabled, the following steps are set in process:
1. When an STP BPDU packet is received, STP treats it as an unauthorized transmission attempt
and shuts down the port that the BPDU came in on.
2. An event message is logged and an SNMP notification trap is generated.
3. The port remains disabled until re-enabled manually by a network administrator.
Caution
This command should only be used to guard edge ports that are not expected to participate in STP
operations. Once BPDU protection is enabled, it will disable the port as soon as any BPDU packet is
received on that interface.

Configuring Loop Protection
You can use BPDU protection for systems that have spanning tree enabled (See “Spanning Tree BPDU
Protection” on page 91), however, the BPDU protection feature cannot detect the formation of loops
when an unmanaged device on the network drops spanning tree packets. To protect against the
formation of loops in these cases, you can enable the Loop Protection feature, which provides
protection by transmitting loop protocol packets out ports on which loop protection has been
enabled. When the switch sends out a loop protocol packet and then receives the same packet on a
port that has send-disable configured, it shuts down the port from which the packet was sent.
You can configure the disable-timer parameter for the amount of time you want the port to remain
disabled (0 to 604800 seconds). If you configure a value of zero, the port will not be re-enabled.
To enable loop protection, enter this command:
ProCurve(config)# loop-protect <port-list>
Syntax: [no] loop-protect <port-list> [receiver-action <send-disable | no-disable> |]
[transmit-interval <1-10> ] | [disable-timer <0-604800>] |
[trap <loop-detected>]
Allows you to configure per-port loop protection on the switch.
[receiver-action <send-disable | no-disable>]
Sets the action to be taken when a loop is detected on the port. The port that received
the loop protection packet determines what action is taken. If send-disable is
configured, the port that transmitted the packet is disabled. If no-disable is
configured, the port is not disabled.
Default: send-disable

How long (in seconds) a port is disabled when a loop has been detected. A value
of zero disables the auto re-enable functionality.
Default: Timer is disabled
[transmit-interval <1-10>]
Allows you to configure the time in seconds between the transmission of loop
protection packets.
Default: 5 seconds

Syntax: aaa port-access <port-list > controlled-directions <both | in>
After you enable MAC-based authentication on specified ports, you can use
the aaa port-access controlled-directions command to configure how a port
transmits traffic before it successfully authenticates a client and enters
the authenticated state.
both (default): Incoming and outgoing traffic is blocked on a port config-
ured for MAC authentication before authentication occurs.
in: Incoming traffic is blocked on a port configured for MAC authentication
before authentication occurs. Outgoing traffic with unknown destination
addresses is flooded on unauthenticated ports configured for web authen-
tication.
Prerequisites: As implemented in 802.1X authentication, the disabling
of incoming traffic and transmission of outgoing traffic on a MAC-
authenticated egress port in an unauthenticated state (using the aaa port-
access controlled-directions in command) is supported only if:
■
The 802.1s Multiple Spanning Tree Protocol (MSTP) or 802.1w Rapid
Spanning Tree Protocol (RSTP) is enabled on the switch. MSTP and
RSTP improve resource utilization while maintaining a loop-free
network.

Notes:
The aaa port-access controlled-direction in command allows Wake-on-LAN traffic to be
■
transmitted on a MAC-authenticated outbound port that has not yet transitioned to
the authenticated state; the controlled-direction both setting prevents transmission of
outbound Wake-on-LAN traffic on a MAC-authenticated port until authentication
occurs.
The Wake-on-LAN feature is used by network administrators to remotely power on a
sleeping workstation (for example, during early morning hours to perform routine
maintenance operations, such as patch management and software updates)
■
Using the aaa port-access controlled-directions in command, you can enable the
transmission of Wake-on-LAN traffic on unauthenticated outbound ports that are
configured for any of the following port-based security features:
•
•
•
802.1X authentication
MAC authentication
Web authentication
Because a port can be configured for more than one type of authentication to protect the
switch from unauthorized access, the last setting you configure with the aaa port-access
controlled-directions command is applied to all authentication methods configured on the
switch.
For information about how to configure and use 802.1X authentication, refer to the
chapter titled “Configuring Port-Based and Client-Based Access Control (802.1X)” in the
Access Security Guide for your switch model.

When a MAC-authenticated port is configured with the controlled-directions in setting,
eavesdrop prevention is not supported on the port.

Scheduled Reload
Additional parameters have been added to the reload command to allow for a scheduled reboot of
the switch via the CLI. The scheduled reload feature supports the following capabilities:
It removes the requirement to physically reboot the switch at inconvenient times (for example, at
1:00 in the morning). Instead, a reload at 1:00 mm/ddcommand can be executed (where mm/
dd is the date the switch is scheduled to reboot). It provides a safety net in situations where a change
is made from a remote location to the running config that inadvertently causes loss of management
access. For example, a newly configured ACL might deny access to the switch from the management
station’s IP address such that the telnet session ceases to function. Scheduling a reload after
command (timed to execute after the necessary configuration work is completed) will ensure that
the switch will reboot automatically. Assuming the ACL changes were not saved to the startup config,
telnet access will then be restored. If the ACL work is completed successfully, with no loss of access,
the scheduled reboot can be cancelled with the reload cancelcommand.

Enhancement (PR_1000408960) — RADIUS-Assigned GVRP VLANs.
How RADIUS-Based Authentication Affects VLAN Operation
Using a RADIUS server to authenticate clients, you can provide port-level security protection from
unauthorized network access for the following authentication methods:
■
802.1X: Port-based or client-based access control to open a port for client access after authenti-
cating valid user credentials.
■
■
MAC address: Authenticates a device’s MAC address to grant access to the network.
Web-browser interface: Authenticates clients for network access using a web page for user login.
N o t e
You canuse 802.1X (port-based or client-based) authentication and either Web or MAC authentication
at the same time on a port, with a maximum of 32 clients allowed on the port. (The default is one
client.) Web authentication and MAC authentication are mutually exclusive on the same port. Also,
you must disable LACP on ports configured for any of these authentication methods. For more
information, refer to the “Configuring Port-Based and User-Based Access Control (802.1X)” and “Web
and MAC Authentication” chapters of the Access Security Guide.
VLAN Assignment on a ProCurve Port
Following client authentication, VLAN configurations on a ProCurve port are managed as follows
when you use 802.1X, MAC, or Web authentication:
■
The port resumes membership in any tagged VLANs for which it is already assigned in the switch
configuration. Tagged VLAN membership allows a port to be a member of multiple VLANs
simultaneously.

Enhancements
Release M.10.33 Enhancements
■
The port is temporarily assigned as a member of an untagged (static or dynamic) VLAN for use
during the client session according to the following order of options.
a. The port joins the VLAN to which it has been assigned by a RADIUS server during client
authentication.
b. If RADIUS authentication does not include assigning the port to a VLAN, then the switch
assigns the port to the authorized-client VLAN configured for the authentication method.
c. If the port does not have an authorized-client VLAN configured, but is configured for
membership in an untagged VLAN, the switch assigns the port to this untagged VLAN.
Operating Notes
■
During client authentication, a port assigned to a VLAN by a RADIUS server or an authorized-
client VLAN configuration is an untagged member of the VLAN for the duration of the authenti-
cated session. This applies even if the port is also configured in the switch as a tagged member
of the same VLAN. The following restrictions apply:
•
If the port is assigned as a member of an untagged static VLAN, the VLAN must already be
configured on the switch. If the static VLAN configuration does not exist, the authentication
fails.
•
If the port is assigned as a member of an untagged dynamic VLAN that was learned through
GVRP, the dynamic VLAN configuration must exist on the switchatthe time of authentication
and GVRP-learned dynamic VLANs for port-access authentication must be enabled
If the dynamic VLAN does not exist or if you have not enabled the use of a dynamic VLAN
for authentication sessions on the switch, the authentication fails.
■
■
To enable the use of a GVRP-learned (dynamic) VLAN as the untagged VLAN used in an
authentication session, enter the aaa port-access gvrp-vlans command.
Enabling the use of dynamic VLANs in an authentication session offers the following benefits:
•
•
You avoid the need of having static VLANs pre-configured on the switch.
You can centralize the administration of user accounts (including user VLAN IDs) on a
RADIUS server.
For information on how to enable the switch to dynamically create 802.1Q-compliant VLANs on
links to other devices using the GARP VLAN Registration Protocol (GVRP), refer to the “GVRP”
chapter in the Advanced Traffic Management Guide.
■
For an authentication session to proceed, a ProCurve port must be an untagged member of the
(static or dynamic) VLAN assigned by the RADIUS server (or an authorized-client VLAN config-
uration). The port temporarily drops any current untagged VLAN membership.
If the port is not already a member of the RADIUS-assigned (static or dynamic) untagged VLAN,
the switch temporarily reassigns the port as an untagged member of the required VLAN (for the
duration of the session). At the same time, if the ProCurve port is already configured as an
untagged member of a different VLAN, the port loses access to the other VLAN for the duration
of the session. (A port can be an untagged member of only one VLAN at a time.)

Enhancements
Release M.10.33 Enhancements
When the authentication session ends, the switch removes the temporary untagged VLAN
assignment and re-activates the temporarily disabled, untagged VLAN assignment.
■
If GVRP is already enabled on the switch, the temporary untagged (static or dynamic) VLAN
created on the port for the authentication session is advertised as an existing VLAN.
If this temporary VLAN assignment causes the switch to disable a different untagged static or
dynamic VLAN configured on the port, the disabled VLAN assignment is not advertised. When
the authentication session ends, the switch:
•
•
Removes the temporary untagged VLAN assignment and stops advertising it.
Re-activates and resumes advertising the temporarily disabled, untagged VLAN assignment.
■
■
If you modify a VLAN ID configuration on a port during an 802.1X, MAC, or Web authentication
session, the changes do not take effect until the session ends.
When a switch port is configured with RADIUS-based authentication to accept multiple 802.1X
and/or MAC or Web authentication client sessions, all authenticated clients must use the same
port-based, untagged VLAN membership assigned for the earliest, currently active client session.
Therefore, on a port where one or more authenticated client sessions are already running, all
such clients are on the same untagged VLAN. If a RADIUS server subsequently authenticates a
new client, but attempts to re-assign the port to a different, untagged VLAN than the one already
in use for the previously existing, authenticated client sessions, the connection for the new client
will fail.
Example of Untagged VLAN Assignment in a RADIUS-Based Authentication Session
The following example shows how an untagged static VLAN is temporarily assigned to a port for use
during an 802.1X authentication session. In the example, an 802.1X-aware client on port A2 has been
authenticated by a RADIUS server for access to VLAN 22. However, port A2 is not configured as a
member of VLAN 22 but as a member of untagged VLAN 33 as shown in Figure Figure 8.

Example of an Active VLAN Configuration
In Figure Figure 8, if RADIUS authorizes an 802.1X client on port A2 with the requirement that the
client use VLAN 22, then:
■
VLAN 22 becomes available as Untagged on port A2 for the duration of the session.
■
VLAN 33 becomes unavailable to port A2 for the duration of the session (because there can be
only one untagged VLAN on any port).
To view the temporary VLAN assignment as a change in the active configuration, use the show vlan
<vlan-id> command as shown in Figure Figure 9, where <vlan-id> is the (static or dynamic) VLAN used
in the authenticated client session.
Figure 9.
Active Configuration for VLAN 22 Temporarily Changes for the 802.1X Session
However, as shown in Figure Figure 8, because VLAN 33 is configured as untagged on port A2 and
because a port can be untagged on only one VLAN, port A2 loses access to VLAN 33 for the duration
of the 802.1X session on VLAN 22.
You can verify the temporary loss of access to VLAN 33 by entering the show vlan 33 command as
shown in Figure Figure 10.

When the 802.1X client session on port A2 ends, the port removes the temporary untagged VLAN
membership. The static VLAN (VLAN 33) that is “permanently” configured as untagged on the
port becomes available again. Therefore, when the RADIUS-authenticated 802.1X session on
port A2 ends, VLAN 22 access on port A2 also ends, and the untagged VLAN 33 access on port
A2 is restored as shown in Figure Figure 11.

Notes:
1. If a port is assigned as a member of an untagged dynamic
VLAN, the dynamic VLAN configuration must exist at the
time of authentication and GVRP for port-access
authentication must be enabled on the switch.
If the dynamic VLAN does not exist or if you have not enabled

Enhancement (PR_1000419928) — The Dynamic ARP Protection feature was added.
Dynamic ARP Protection
Introduction
On the VLAN interfaces of a routing switch, dynamic ARP protection ensures that only valid ARP
requests and responses are relayed or used to update the local ARP cache. ARP packets with invalid
IP-to-MAC address bindings advertised in the source protocol address and source physical address
fields are discarded. For more information about the ARP cache, refer to “ARP Cache Table” in the
Multicast and Routing Guide.
ARP requests are ordinarily broadcast and received by all devices in a broadcast domain. Most ARP
devices update their IP-to-MAC address entries each time they receive an ARP packet even if they
did not request the information. This behavior makes an ARP cache vulnerable to attacks.
BecauseARP allowsa nodeto updateitscache entries onother systemsbybroadcasting orunicasting
a gratuitous ARP reply, an attacker can send his own IP-to-MAC address binding in the reply that
causes all traffic destined for a VLAN node to be sent to the attacker's MAC address. As a result, the
attacker can intercept traffic for other hosts in a classic "man-in-the-middle" attack. The attacker
gains access to any traffic sent to the poisoned address and can capture passwords, e-mail, and VoIP
calls or even modify traffic before resending it.
Another way in which the ARP cache of known IP addresses and associated MAC addresses can be
poisonedisthroughunsolicitedARPresponses. Forexample, anattackercan associatetheIPaddress
of the network gateway with the MAC address of a network node. In this way, all outgoing traffic is
prevented from leaving the network because the node does not have access to outside networks. As
a result, the node is overwhelmed by outgoing traffic destined to another network.
Dynamic ARP protection is designed to protect your network against ARP poisoning attacks in the
following ways:
■
■
■
Allows you to differentiate between trusted and untrusted ports.
Intercepts all ARP requests and responses on untrusted ports before forwarding them.
Verifies IP-to-MAC address bindings on untrusted ports with the information stored in the lease
database maintained by DHCP snooping and user-configured static bindings (in non-DHCP
environments):
•
If a binding is valid, the switch updates its local ARP cache and forwards the packet.

Enhancements
Release M.10.35 Enhancements
•
If a binding is invalid, the switch drops the packet, preventing other network devices from
receiving the invalid IP-to-MAC information.
DHCP snooping intercepts and examines DHCP packets received on switch ports before
forwarding the packets. DHCP packets are checked against a database of DHCP binding infor-
mation. Each binding consists of a client MAC address, port number, VLAN identifier, leased IP
address, and lease time. The DHCP binding database is used to validate packets by other security
features on the switch.
If you have already enabled DHCP snooping on a switch, you may also want to add static IP-to-
MAC address bindings to the DHCP snooping database so that ARP packets from devices that
have been assigned static IP addresses are also verified.
■
Supports additional checks to verify source MAC address, destination MAC address, and IP
address.
ARP packets that contain invalid IP addresses or MAC addresses in their body that do not match
the addresses in the Ethernet header are dropped.
When dynamic ARP protection is enabled, only ARP request and reply packets with valid IP-to-MAC
address bindings in their packet header are relayed and used to update the ARP cache.
Dynamic ARP protection is implemented in the following ways on a switch:
■
You can configure dynamic ARP protection only from the CLI; you cannot configure this feature
from the web or menu interfaces.
■
Line rate—Dynamic ARP protection copies ARP packets to the switch CPU, evaluates the
packets, and then re-forwards them through the switch software. During this process, if ARP
packets are received at too high a line rate, some ARP packets may be dropped and will need to
be retransmitted.
■
The SNMP MIB, HP-ICF-ARP-PROTECT-MIB, is created to configure dynamic ARP protection
and to report ARP packet-forwarding status and counters.
Enabling Dynamic ARP Protection
To enable dynamic ARP protection for VLAN traffic on a routing switch, enter the arp protect vlan
command at the global configuration level.
Syntax: [no] arp protect vlan [vlan-range]
vlan-range
Specifies a VLAN ID or a range of VLAN IDs from
one to 4094; for example, 1–200.
An example of the arp protect vlan command is shown here:
ProCurve(config)# arp protect vlan 1-101

Enhancements
Release M.10.35 Enhancements
Configuring Trusted Ports
In a similar way to DHCP snooping, dynamic ARP protection allows you to configure VLAN interfaces
in two categories: trusted and untrusted ports. ARP packets received on trusted ports are forwarded
without validation.
By default, all ports on a switch are untrusted. If a VLAN interface is untrusted:
■
The switch intercepts all ARP requests and responses on the port.
■
Each intercepted packet is checked to see if its IP-to-MAC binding is valid. If a binding is invalid,
the switch drops the packet.
You must configure trusted ports carefully. For example, in the topology in Figure 8, Switch B may
not see the leased IP address that Host 1 receives from the DHCP server. If the port on Switch B that
is connected to Switch A is untrusted and if Switch B has dynamic ARP protection enabled, it will
see ARP packets from Host 1 as invalid, resulting in a loss of connectivity.
On the other hand, if Switch A does not support dynamic ARP protection and you configure the port
on Switch B connected to Switch A as trusted, Switch B opens itself to possible ARP poisoning from
hosts attached to Switch A.
Figure 12. Configuring Trusted Ports for Dynamic ARP Protection
Take into account the following configuration guidelines when you use dynamic ARP protection in
your network:
■
You should configure ports connected to other switches in the network as trusted ports. In this
way, all network switches can exchange ARP packets and update their ARP caches with valid
information.
■
Switches that do not support dynamic ARP protection should be separated by a router in their
own Layer 2 domain. Because ARP packets do not cross Layer 2 domains, the unprotected
switches cannot unknowingly accept ARP packets from an attacker and forward them to
protected switches through trusted ports.

Enhancements
Release M.10.35 Enhancements
To configure one or more Ethernet interfaces that handle VLAN traffic as trusted ports, enter the arp
protect trust command at the global configuration level. The switch does not check ARP requests and
responses received on a trusted port.
Syntax: [no] arp protect trust <port-list>
port-list
Specifies a port number or a range of port
numbers. Separate individual port numbers or
ranges of port numbers with a comma; for
example: c1-c3, c6.
An example of the arp protect trust command is shown here:
ProCurve(config)# arp protect trust b1-b4, d1
Adding an IP-to-MAC Binding to the DHCP Database
A routing switch maintains a DHCP binding database, which is used for DHCP and ARP packet
validation. Both the DHCP snooping and DHCP Option 82 insertion features maintain the lease
database by learning the IP-to-MAC bindings on untrusted ports. Each binding consists of the client
MAC address, port number, VLAN identifier, leased IP address, and lease time.
If your network does not use DHCP or if some network devices have fixed, user-configured IP
addresses, you can enter staticIP-to-MAC addressbindingsin the DHCP binding database. The switch
uses manually configured static bindings for DHCP snooping and dynamic ARP protection.
To add the static configuration of an IP-to-MAC binding for a port to the database, enter the ip source
binding command at the global configuration level.
Syntax: [no] ip source binding <mac-address> vlan <vlan-id> <ip-address>
interface <port-number>
mac-address Specifies a MAC address to bind with a VLAN
and IP address on the specified port in the
DHCP binding database.
vlan <vlan-id> Specifies a VLAN ID number to bind with the
specified MAC and IP addresses on the speci-
fied port in the DHCP binding database.
ip-address
Specifies an IP address to bind with a VLAN
and MAC address on the specified port in the
DHCP binding database.

Specifies the port number on which the IP-to-
MAC address and VLAN binding is configured

Configuring Additional Validation Checks on ARP Packets
Dynamic ARP protection can be configured to perform additional validation checks on ARP packets.
By default, no additional checks are performed. To configure additional validation checks, enter the
arp protect validate command at the global configuration level.
Syntax: [no] arp protect validate <[src-mac] | [dst-mac] | [ip]>
src-mac (Optional) Drops any ARP request or response
packet in which the source MAC address in the
Ethernet header does not match the sender MAC
address in the body of the ARP packet.
dst-mac (Optional) Dropsany unicast ARP response packet
in which the destination MAC address in the
Ethernet header does not mach the target MAC
address in the body of the ARP packet.
ip
(Optional) Drops any ARP packet in which the
sender IP address is invalid. Drops any ARP
response packet in which the target IP address is
invalid. Invalid IP addresses include: 0.0.0.0,
255.255.255.255, all IP multicast addresses, and
all Class E IP addresses.
You can configure one or more of the validation checks. The following example of the arp protect
validate command shows how to configure the validation checks for source MAC address and
destination AMC address:

Configuring MSTP Port Connectivity Parameters
With release K.12.04, all ports are configured as auto-edge-ports by default, and the spanning tree
edge-port option has been removed. This section describes selected spanning-tree <port-list> com-
mand parameters for enhanced operation.
Basic port connectivity parameters affect spanning-tree links at the global level. Therefore, in most
cases, ProCurve recommends that you use the revised default settings for these parameters and apply
changes on a per-port basis only where a non-default setting is clearly indicated by the circumstances
of individual links (for example, see the root-guard option below).
To display the spanning-tree settings for each port, use the show spanning-tree config command.
Syntax: [no] spanning-tree < port-list > < auto-edge-port | admin-edge-port | mcheck | root-guard |
tcn-guard >
[auto-edge-port ]
Enablesauto-edge-port operationforMSTP, andsupportstheautomaticdetection
of edge ports. (Default: Yes, enabled)
The port will look for BPDUs for 3 seconds; if there are none it begins forwarding
packets. If admin-edge-port is enabled for a port, the setting for auto-edge-port is
ignored whether set to yes or no. If admin-edge-port is disabled, and auto-edge-
port has not been disabled, then the auto-edge-port setting controls the behavior
of the port.
The no spanning-tree < port-list > auto-edge-port command disables auto-edge-port
operation on the specified ports.
[ admin-edge-port ]
Enables admin-edge-port for RSTP/MSTP. If a bridge or switch is detected on the
segment, the port automatically operates as non-edge, not enabled. (Default: No
- disabled)
If admin-edge-port is disabled on a port and auto-edge-port has not been disabled,
the auto-edge-port setting controls the behavior of the port.
The no spanning-tree < port-list > admin-edge-port command disables admin-edge-
port operation on the specified ports.
[mcheck ]
Forces a port to send RSTP/MSTP BPDUs for 3 seconds. This allows for another
switch connected to the port and running RSTP to establish its connection
quickly and for identifying switches running 802.1D STP. If the whole-switch
force-version parameter is set to stp-compatible, the switch ignores the mcheck
setting and sends 802.1D STP BPDUs out all ports.

Enhancements
Release M.10.37 Enhancements
[root-guard]
MSTP only. When a port is enabled as root-guard, it cannot be selected as the root
port even if it receives superior STP BPDUs. The port is assigned an “alternate”
port role and enters a blocking state if it receives superior STP BPDUs. The
BPDUs received on a root-guard port are ignored. All other BPDUs are accepted
and the external devices may belong to the spanning tree as long as they do not
claim to be the Root device. (Default: No - disabled)
Note: In standard Spanning Tree Protocol operation, the calculation of active
network topologies may be an issue when switches outside the core region of a
network are under shared or limited administrative control. Such a switch may
become a Root Bridge for the entire network and create non-optimal forwarding
paths. By enabling the root-guard feature on ports that face outside the core
network, external boundaries for the core network are created to ensure the Root
Bridge is located within the core network.
[tcn-guard]
When tcn-guard is enabled for a port, it causes the port to stop propagating
received topology change notifications and topology changes to other ports.
(Default: No - disabled)
Syntax: spanning-tree < port-list > < hello-time | path-cost | point-to-point-mac | priority >
[ hello-time < global | 1 - 10 >
When the switch is the CIST root, this parameter specifies the interval (in
seconds) between periodic BPDU transmissions by the designated ports. This
interval also applies to all ports in all switches downstream from each port in
the < port-list >. A setting of global indicates that the ports in < port-list > on the
CIST root are using the value set by the global spanning-tree hello-time value.
When a given switch “X” is not the CIST root, the per-port hello-time for all active
ports on switch “X” is propagated from the CIST root, and is the same as the
hello-time in use on the CIST root port in the currently active path from switch
“X” to the CIST root. (That is, when switch “X” is not the CIST root, then the
upstream CIST root’s port hello-time setting overrides the hello-time setting
configured on switch “X”. (Default Per-Port setting: Use Global. Default Global
Hello-Time: 2.)
[ path-cost < auto | 1..200000000 > ]
Assigns an individual port cost that the switch uses to determine which ports
are forwarding ports in a given spanning tree. In the default configuration
(auto) the switch determines a port’s path cost by the port’s type:
– 10 Mbps: 2000000
– 100 Mbps: 200000
– 1 Gbps: 20000

point-to-point-mac <true | false | auto >
This parameter informs the switch of the type of device to which a specific port
connects.
True (default): Indicates a point-to-point link to a device such as a switch,
bridge, or end-node.
False: Indicates a connection to a hub (which is a shared LAN segment).
Auto: Causes the switch to set False on the port if it is not running at full duplex.
(Connections to hubs are half-duplex.)
priority < 0..15 >
MSTP uses this parameter to determine the port(s) to use for forwarding. The
port with the lowest assigned value has the highest priority. While the actual
priority range is 0 to 240, this command specifies the priority as a multiplier
(0-15) of 16. That is, when you specify a priority multiplier of 0-15, the actual
priority assigned to the switch is:
(priority-multiplier) x 16 = priority
The default priority-multiplier value is 8.
For example, if you configure “2” as the priority multiplier for a given port,
then the actual priority is 32. Thus, after you specify the port priority
multiplier, the switch displays the actual port priority (and not the multiplier)
in the show spanning-tree config display. You can view the actual multiplier
setting for ports by executing show running and looking for an entry in this form:
spanning-tree <port-list> priority <priority-multiplier>
For example, configuring port 2 with a priority multiplier of “3” results in this
line in the show running-config output:

Enabling and Configuring SNMP Informs
You can use the snmp-server informs command (SNMPv2c and SNMPv3 versions) to send notifications
when certain events occur. When an SNMP Manager receives an informs request, it can send an SNMP
response back to the sending agent. This lets the agent know that the informs request reached its
destination and that traps can be sent successfully to that destination.
Informs requests can be sent several times until a response is received from the SNMP manager or
the configured retry limits are reached. The request may also timeout.
To enable SNMP informs, enter this command:
Syntax: [no] snmp-server enable informs
Enables or disables the informs option for SNMP.
Default: Disabled
To configure SNMP informs request options, use the following commands.
Syntax: [no] snmp-server informs [retries<retries>] [timeout<seconds>] [pending <pending>]
Allows you to configure options for SNMP informs requests.
retries: Maximum number of times to resend an informs request. Default: 3
timeout: Number of seconds to wait for an acknowledgement before resending the
informs request. Default: 30 seconds
pending: Maximum number of informs waiting for acknowledgement at any one
time. When the maximum configured number is reached, older pending informs
are discarded. Default: 25
To specify the manager that receives the informs request, use the snmp-server host command.

Enhancement (PR_1000428213) — This software enhancement adds the ability to
configure a secondary authentication method to be used when the RADIUS server is
unavailable for the primary port-access method.
RADIUS Server Unavailable
Overview
In certain situations, RADIUS servers can become isolated from the network. Users are not able to
access the network resources configured with RADIUS access protection and are rejected. To
address this situation, configuring the “authorized” secondary authentication method allows users
unconditional access to the network when the primary authentication method fails because the
RADIUS servers are unreachable.
Configuring RADIUS Authentication
You can configure the switch for RADIUS authentication through the following access methods:
■
■
■
■
Console: Either direct serial-port connection or modem connection.
Telnet: Inbound Telnet must be enabled (the default).
SSH: To use RADIUS for SSH access, first configure the switch for SSH operation.
Web: Enables RADIUS authentication for web browser interface access to the switch.
You can configure radius as the primary password authentication method for the above access
methods. You also need to select either local, none, or authorized as a secondary, or backup, method..
Syntax: aaa authentication < console | telnet | ssh | web > < enable | login > radius
Configures RADIUS as the primary password authentication method for console, Telnet,
SSH, and the web browser interface. (The default primary < enable | login > authentica-
tion is local.)
[< local | none | authorized >]
Provides options for secondary authentication (default: none).
Caution
Configuring authorized as the secondary authentication method used when there is a failure accessing
the RADIUS servers allows clients to access the network unconditionally. Use this method with care.

Enhancements
Release M.10.39 Enhancements
You can configure local, chap-radius or eap-radius as the primary password authentication method
for the port-access method. You also need to select none or authorized as a secondary, or backup,
method.
Syntax: aaa authentication port-access <chap-radius |eap-radius | local>
Configures local, chap-radius, or eap-radius as the primary password authentication
method for port-access. The default primary authentication is local.
[<none | authorized >]
Provides options for secondary authentication. The none option specifies
that a backup authentication method is not used. The authorized option
allows access without authentication. (default: none).
You can configure chap-radius as the primary password authentication method for web-based or mac-
based port-access methods. You also need to select none or authorized as a secondary, or backup,
method.
Syntax: aaa authentication <mac-based | web-based> chap-radius
Configures chap-radius as the primary password authentication method for mac-based
or web-based port access.
[<none | authorized >]
Provides options for secondary authentication. The none option specifies
that a backup authentication method is not used. The authorized option
allows access without authentication. (default: none).
Figure 1 shows an example of the show authentication command displaying authorized as the second-
ary authentication method for port-access, Web-auth access, and Mac-auth access. Since the config-
uration of authorized means no authentication will be performed and the client has unconditional
access to the network, the “Enable Primary” and “Enable Secondary” fields are not applicable (N/A).

Specifying the MAC Address Format
The MAC address format command has been enhanced to allow upper-case letters to be used for the
hexadecimal numbers when indicating the MAC address in RADIUS packets for MAC-based authen-
tication.
Syntax: aaa port-access mac-based addr-format <no-delimiter | single-dash | multi-dash | multi-colon |
no-delimiter-uppercase | single-dash-uppercase | multi-dash-uppercase |
multi-colon-uppercase>
Specifies the MAC address format to be used in the RADIUS request message.
This format must match the format used to store the MAC addresses in the
RADIUS server. (Default: no-delimiter)
no-delimiter — specifies an aabbccddeeff format.
single-dash — specifies an aabbcc-ddeeff format.
multi-dash — specifies an aa-bb-cc-dd-ee-ff format.
multi-colon — specifies an aa:bb:cc:dd:ee:ff format.
no-delimiter-uppercase — specifies an AABBCCDDEEFF format.
single-dash-uppercase — specifies an AABBCC-DDEEFF format
multi-dash-uppercase — specifies an AA-BB-CC-DD-EE-FF format
multi-colon-uppercase — specifies an AA:BB:CC:DD:EE:FF format.
For example, using the multi-colon-uppercase option, the MAC address would appear as follows:
AA:BB:CC:DD:EE:FF

Enhancement (PR_1000415155) — The ARP age timer was enhanced from the previous
limit of 240 minutes to allow for configuration of values up to 1440 minutes (24 hours) or
"infinite" (99,999,999 seconds or 3.2 years).
ARP Age Timer Increase
The ARP age is the amount of time the switch keeps a MAC address learned through ARP in the ARP
cache. The switch resets the timer to zero each time the ARP entry is refreshed and removes the entry
if the timer reaches the ARP age.
You can increase the ARP age timeout maximum to 24 hours or more with this command:
Syntax: [no] ip arp-age <[1...1440] | infinite>
AllowstheARPagetobesetfrom1to 1440minutes(24hours). Iftheoption“infinite”
is configured, the internal ARP age timeout is set to 99,999,999 seconds
(approximately 3.2 years). An arp-age value of 0 (zero) is stored in the
configuration file to indicate that “infinite” has been configured. This value also
displays with the show commands and in the menu display (Menu > Switch
Configuration > IP Config).
Default: 20 minutes.

■
Enhancement (PR_1000452407) — The Dynamic IP Lockdown feature was added for the
3400cl series switches.
Dynamic IP Lockdown
The Dynamic IP Lockdown feature is used to prevent IP source address spoofing on a per-port and
per-VLAN basis. When dynamic IP lockdown is enabled, IP packets in VLAN traffic received on a port
are forwarded only if they contain a known source IP address and MAC address binding for the port.
The IP-to-MAC address binding can either be statically configured or learned by the DHCP Snooping
feature.

Protection Against IP Source Address Spoofing
Many network attacks occur when an attacker injects packets with forged IP source addresses into
the network. Also, some network services use the IP source address as a component in their
authentication schemes. For example, the BSD “r” protocols (rlogin, rcp, rsh) rely on the IP source
address for packet authentication. SNMPv1 and SNMPv2c also frequently use authorized IP address
lists to limit management access. An attacker that is able to send traffic that appears to originate
from an authorized IP source address may gain access to network services for which he is not
authorized.
Dynamic IP lockdown provides protection against IP source address spoofing by means of IP-level
port security. IP packets received on a port enabled for dynamic IP lockdown are only forwarded if
they contain a known IP source address and MAC address binding for the port.
Dynamic IP lockdown uses information collected in the DHCP Snooping lease database and through
statically configured IP source bindings to create internal, per-port lists. The internal lists are
dynamically createdfrom knownIP-to-MAC addressbindings tofilterVLANtrafficonboththe source
IP address and source MAC address.
Differences Between Switch Platforms
There are some differences in the feature set and operation of Dynamic IP Lockdown, depending on
the switch on which it is implemented. These are listed below.
■
There is no restriction on GVRP on 3500/5400 switches. On 2600/2800/3400cl switches,
Dynamic IP Lockdown is not supported if GVRP is enabled on the switch.
■
Dynamic IP Lockdown has the host limits shown in the table below. There is a DHCP
snooping limit of 8,000 entries.
Switch
Number of Hosts
Comments
3500/5400
64 bindings per port
Up to 4096 bindings per switch
This limit is shared with DHCP snooping because
they both use the snooping database.
3400cl/2800
32 bindings per port
Up to 32 VLANs with DHCP snooping
enabled
This is not guaranteed as the hardware
resources are shared with QoS.
2600
8 bindings per port
Up to 8 VLANs with DHCP snooping
enabled
This is not guaranteed as the hardware
resources are shared with QoS.
■
■
A source is considered “trusted” for all VLANs if it is seen on any VLAN without DHCP
snooping enabled.
On the ProCurve switch series 5400 and 3500, dynamic IP lockdown is supported on a port
configured for statically configured port-based ACLs.

Release M.10.43 Enhancements
Prerequisite: DHCP Snooping
Dynamic IP lockdown requires that you enable DHCP snooping as a prerequisite for its operation on
ports and VLAN traffic:
■
Dynamic IP lockdown only enables traffic for clients whose leased IP addresses are already
stored in the lease database created by DHCP snooping or added through a static configuration
of an IP-to-MAC binding.
Therefore, if you enable DHCP snooping after dynamic IP lockdown is enabled, clients with an
existing DHCP-assigned address must either request a new leased IP address or renew their
existing DHCP-assigned address. Otherwise, a client’s leased IP address is not contained in the
DHCP binding database. As a result, dynamic IP lockdown will not allow inbound traffic from
the client.
■
It is recommended that you enable DHCP snooping a week before you enable dynamic IP
lockdown to allow the DHCP binding database to learn clients’ leased IP addresses. You must
also ensure that the lease time for the information in the DHCP binding database lasts more than
a week.
Alternatively, you can configure a DHCP server to re-allocate IP addresses to DHCP clients. In
this way, you repopulate the lease database with current IP-to-MAC bindings.
■
The DHCP binding database allows VLANs enabled for DHCP snooping to be known on ports
configured for dynamic IP lockdown. As new IP-to-MAC address and VLAN bindings are
learned, a corresponding permit rule is dynamically created and applied to the port
(preceding the final deny any vlan <VLAN_IDs> rule as shown in the example in Figure 3).
These VLAN_IDs correspond to the subset of configured and enabled VLANS for which
DHCP snooping has been configured.
■
■
For dynamic IP lockdown to work, a port must be a member of at least one VLAN that has
DHCP snooping enabled.
Disabling DHCP snooping on a VLAN causes Dynamic IP bindings on Dynamic IP Lockdown-
enabled ports in this VLAN to be removed. The port reverts back to switching traffic as usual.
Filtering IP and MAC Addresses Per-Port and Per-VLAN
This section contains an example that shows the following aspects of the Dynamic IP Lockdown
feature:
■

in the DHCP Snooping lease database and statically configured IP-to-MAC address bindings

Enabling Dynamic IP Lockdown
To enable dynamic IP lockdown on all ports or specified ports, enter theipsource-lockdown command
at the global configuration level. Use the no form of the command to disable dynamic IP lockdown.
Syntax: [no] ip source-lockdown [port-list]
Enables dynamic IP lockdown globally on all ports or on
specified ports on the routing switch.
Operating Notes
■
Dynamic IP lockdown is enabled at the port configuration level and applies to all bridged or
routed IP packets entering the switch. The only IP packets that are exempt from dynamic IP
lockdown are broadcast DHCP request packets, which are handled by DHCP snooping.
■
DHCP snooping is a prerequisite for Dynamic IP Lockdown operation. The following restrictions
apply:
•
DHCP snooping is required for dynamic IP lockdown to operate. To enable DHCP snooping,
enter the DHCP-Snooping command at the global configuration level.
•
Dynamic IP lockdown only filters packets in VLANs that are enabled for DHCP snooping. In
order for Dynamic IP lockdown to work on a port, the port must be configured for at least
one VLAN that is enabled for DHCP snooping.
ToenableDHCPsnooping onaVLAN, enterthe dhcp-snoopingvlan [vlan-id-range] command
at the global configuration level or the dhcp-snooping command at the VLAN configuration
level.
•
Dynamic IP lockdown is not supported on a trusted port. (However, note that the DHCP
server must be connected to a trusted port when DHCP snooping is enabled.)
By default, all ports are untrusted. To remove the trusted configuration from a port, enter
the no dhcp-snooping trust <port-list> command at the global configuration level.
For more information on how to configure and use DHCP snooping, refer to the “Configuring
Advanced Threat Protection” chapter in the Access Security Guide.
■
After you enter the ip source-lockdown command (enabled globally with the desired ports entered
in<port-list>), thedynamic IPlockdownfeatureremainsdisabledonaportifanyofthefollowing
conditions exist:
•
•
•
If DHCP snooping has not been globally enabled on the switch.
If the port is not a member of at least one VLAN that is enabled for DHCP snooping.
If the port is configured as a trusted port for DHCP snooping.
Dynamic IP lockdown is activated on the port only after you make the following configuration
changes:
•
•
Enable DHCP snooping on the switch.
Configure the port as a member of a VLAN that has DHCP snooping enabled.

■
■
If you enable dynamic IP lockdown on a port, you cannot add the port to a trunk.
Dynamic IP lockdown must be removed from a trunk before the trunk is removed.
Adding an IP-to-MAC Binding to the DHCP Binding Database
A switch maintains a DHCP binding database, which is used for dynamic IP lockdown as well as for
DHCP and ARP packet validation. The DHCP snooping feature maintains the lease database by
learning the IP-to-MAC bindings of VLAN traffic on untrusted ports. Each binding consists of the
client MAC address, port number, VLAN identifier, leased IP address, and lease time.
Dynamic IP lockdown supports a total of 4K static and dynamic bindings with up to 64 bindings per
port. When DHCP snooping is enabled globally on a VLAN, dynamic bindings are learned when a
client on the VLAN obtains an IP address from a DHCP server. Static bindings are created manually
with the CLI or from a downloaded configuration file.
When dynamic IP lockdown is enabled globally or on ports the bindings associated with the ports
are written to hardware. This occurs during these events:
■
■
■
■
Switch initialization
Hot swap
A dynamic IP lockdown-enabled port is moved to a DHCP snooping-enabled VLAN
DHCP snooping or dynamic IP lockdown characteristics are changed such that dynamic IP
lockdown is enabled on the ports
Potential Issues with Bindings
■
When dynamic IP lockdown enabled, and a port or switch has the maximum number of
bindings configured, the client DHCP request will be dropped and the client will not receive
an IP address through DHCP.
■
■
When dynamic IP lockdown is enabled and a port is configured with the maximum number
of bindings, adding a static binding to the port will fail.
When dynamic IP lockdown is enabled globally, the bindings for each port are written to
hardware. If global dynamic IP lockdown is enabled and disabled several times, it is possible
to run out of buffer space for additional bindings. The software will delay adding the bindings
to hardware until resources are available.

the IP-to-MAC binding from the database.
Syntax: [no] ip source-binding <vlan-id> <ip-address> <mac-address> <port-

vlan-id
Specifies a valid VLAN ID number to bind with
the specified MAC and IP addresses on the port

Enhancement (PR_0000001316) — The MSTP VLAN Assignment is enhanced.
MSTP VLAN Configuration Enhancement
Caution
Whenthissoftwareversionisinstalled, thepriorVLANID-to-MSTImappingsdonotchange. However,
this enhancement is not backward-compatible. If you install a software version prior to this version,
and you have configured MSTI entries instances mapped to VLANs, they will be removed from the
configuration file when booting to the prior version of software. You must remove all MSTP mappings
from the config file and then reconfigure the instance mapping after you are running the desired
software version.
If you want to save a copy of the switch configuration file to a tftp server before you install this
version, use this command:
ProCurve(config)# copy startup-config tftp <ip-address tftp server>
<filename>
where <filename>is the name you choose for the pre-enhancement configuration file that you are
saving.
Overview
The MSTP VLAN configuration enhancement allows you to preconfigure an MSTP regional topology
and ensure that the same VLAN ID-to-MSTI assignments exist on each MSTP switch in the region.
The defaultbehavior ofthespanning-treeinstance vlan command changes so that, before a static VLAN
is configured or a dynamic VLAN is learned on the switch, you can preconfigure its VLAN ID-to-MSTI
mapping. Later, when the VLAN is created, it is automatically assigned to the MSTI to which you had
previously mapped it.
By supporting preconfigured VLAN ID-to-MSTI topologies, the MSTP VLAN configuration enhance-
ment provides the following benefits:
■
Scalability: In a network design in which you plan to use a large number of VLANs, you can
preconfigure identical VLAN ID-to-MSTI mappings on all switches in a single, campus-wide MST
region, regardless of the specific VLANs that you later configure on each switch. After the initial
VLAN ID-to-MSTI mapping, you can decide on the exact VLANs that you need on each switch.

Enhancements
Release M.10.65 Enhancements
All switches in a region must be configured with the same VLAN ID-to-MSTI mappings and the
same MSTP configuration identifiers (region name and revision number).
■
■
Flexibility: By preconfiguring identical VLAN ID-to-MSTI mappings on all switches in an MST
region, you can combine switches that support different maximum numbers of VLANs.
Network stability: You can reduce the interruptions in network connectivity caused by the
regeneration of spanning trees in the entire network each time a configuration change in VLAN-
to-MSTI mapping is detected on a switch. The negative impact on network performance is
reduced if all newly created VLANs are pre-mapped to the correct MST instances. Later, VLAN
creation and deletion are ignored by MSTP and no interruption in spanning-tree traffic occurs.
■
Usability: Dynamically learned GVRP VLANs can be mapped to MSTIs and support MSTP load
balancing.
Enabling MSTP on the Switch
If you have not enabled MSTP on the switch, you must enable it to use this feature. To enable MSTP,
perform these steps.
1. Enter the command to enable MSTP:
ProCurve(config)# spanning-tree protocol-version mstp
You will see this message:
STP version was changed. To activate the change you must save the
configuration to flash and reboot the device.
2. Save the configuration change to flash.
ProCurve(config)# write mem
3. Reboot the switch.
ProCurve(config)# reload
Device will be rebooted, do you want to continue [y/n]? y
PreConfiguring VLANs in an MST Instance
When you configure an MSTP regional topology, you create multiple spanning-tree instances. Each
MST instance provides a fully connected active topology for a particular set of VLANs.
Each switch in an MSTP region is configured with the following set of common parameters:
■
■
■
Region name (spanning-tree config-name)
Region revision number (spanning-tree config-revision)
Identical VLAN ID-to-MSTI mapping (spanning-tree instance vlan)

Enhancements
Release M.10.65 Enhancements
Each MST instance supports a different set of VLANs. A VLAN that is mapped to an MST instance
cannot be a member of another MST instance.
The MSTP VLAN Configuration enhancement allows you to ensure that the same VLAN ID-to-MSTI
assignments exist on each MSTP switch in a region. Before a static VLAN is configured or a dynamic
VLAN is learned on the switch, you can use the spanning-tree instance vlan command to map VLANs
to each MST instance in the region. Later, when the VLAN is created, the switch automatically assigns
it to the MST instance to which you had previously mapped it.
Syntax: [no] spanning-tree instance < 1..16 > vlan < vid [ vid..vid ] >
no spanning-tree instance < 1..16 >
Configuring MSTP on the switch automatically configures the IST instance and
places all statically and dynamically configured VLANs on the switch into the IST
instance. This command creates a new MST instance (MSTI) and moves the VLANs
you specify from the IST to the MSTI.
You must map at least one VLAN to an MSTI when you create it. You cannot map
a VLAN ID to more than one instance. You can create up to 16 MSTIs in a region.
The no form of the command removes one or more VLANs from the specified MSTI.
If no VLANs are specified, the no form of the command deletes the specified MSTI.
When you remove a VLAN from an MSTI, the VLAN returns to the IST instance,
where it can remain or be re-assigned to another MSTI configured in the region.
Note: The valid VLAN IDs that you can map to a specified MSTI are from 1 to 4094.
The VLAN ID-to-MSTI mapping does not require a VLAN to be already configured
on the switch. The MSTP VLAN enhancement allows you to preconfigure MSTP
topologies before the VLAN IDs associated with each instance exist on a switch.
When you use preconfigured VLAN ID-to-MSTI topologies, ensure that MSTP
switches remain in the same region by mapping all VLAN IDs used in the region
to the same MSTIs on each regional switch.
Configuring MSTP Instances with the VLAN Range Option
If you use the spanning-tree instance command with the VLAN range option, even if the range includes
VLANs that are not currently present on the switch, the entire range of VLANs is configured. For
example, if VLANs 1, 5, and 7 are currently present and you enter this command:
ProCurve(config)# spanning-tree instance 1 vlan 1-10
then all the VLANs from 1 through 10 are included, even those VLANs that are not present.
Figure 23 shows an example of an MSTP instance configured with the VLAN range option. All the
VLANs are included in the instance whether they exist or not.

Note
If you want all switches to be in the same MST region, they should all have a software version that
supports this enhancement installed, or have the same VLANS configured.
It is likely that switches with a VLAN range configured prior to this enhancement and switches with
a VLAN range configured after updating the switch with this enhancement will have different
Configuration Digests.
The Common Spanning Tree (CST) will still have the correct root associations.
Operating Notes
■
Configuring MSTP on the switch automatically configures the Internal Spanning Tree (IST)
instance and places all statically and dynamically configured VLANs on the switch into the
IST instance. The spanning-tree instance vlan command creates a new MST instance and
moves the VLANs you specify from the IST to the MSTI.
You must map a least one VLAN ID to an MSTI when you create it. You cannot map a VLAN ID
to more than one instance. You can create up to 16 MSTIs in a region.
■
The no form of the spanning-tree instance vlan command removes one or more VLANs from
the specified MSTI. If no VLANs are specified, the no form of the command deletes the
specified MSTI.
When you remove a VLAN from and MSTI, the VLAN returns to the IST instance, where it can
remain or be re-assigned to another MSTI configured in the region.

Enhancements
Release M.10.66 Enhancements
■
If you enter the spanning-tree instance vlan command before a static or dynamic VLAN is
configured on the switch to preconfigure VLAN ID-to-MSTI mappings, no error message is
displayed. Later, each newly configured VLAN that has already been associated with an MSTI
is automatically assigned to the MSTI.
This new default behavior differs from automatically including configured (static and dynamic)
VLANs in the IST instance and requiring you to manually assign individual static VLANs to an
MSTI.
■
The valid VLAN IDs that you can map to a specified MSTI are from 1 to 4094. The VLAN ID-
to-MSTI mapping does not require a VLAN to be already configured on the switch. The MSTP
VLAN enhancement allows you to preconfigure MSTP topologies before the VLAN IDs
associated with each instance exist on a switch.
■
■
When you use preconfigured VLAN ID-to-MSTI topologies, ensure that MSTP switches
remain in the same region by mapping all VLAN IDs used in the region to the same MSTIs on
each regional switch.
Whenyouupdateswitchsoftware, theexistingMSTPtopologyconfigurationisautomatically
saved. All existing VLAN ID-to-MSTI assignments are maintained on a switch for uninter-
rupted MSTP network operation.

Configure Logging via SNMP
Debug messages generated by the software can be sent to a syslog server. This feature provides the
ability to enter addresses and filter parameters for syslog using SNMP, which allows more options
for remote access and management of the switch. The HP enterprise MIB hpicfSyslog.mib is added
to allow the configuration and monitoring of syslog. (RFC 3164 supported)
The CLI has some additional parameters that permit interoperability with SNMP that are explained
below.

Authentication (PR_0000011138) — If the RADIUS server becomes unavailable, the eap-
radius authorized option allows the switch to authenticate devices. If the response time of the
RADIUS subsystem is greater than the server-timeout value on the switch or the device
supplicant then switch will not be able to authenticate devices, and no warning of this failure

stance), there is no indication of why the 'failure' is occurring to help the network adminis-
trator understand what is happening. This fix adds log messages similar to the following.

DHCP—Snooping (PR_0000019155) — DHCP-Snooping does not correctly identify that
a packet is a fragment, and drops UDP Fragments if a hex value of 44 (68 Decimal) is present
in the payload where the header is usually located (in a non-fragment).
Unauthenticated VLAN (PR_0000010533) — The switch allows an inherent configura-
tion conflict; an unauthenticated VLAN (unauth-vid) can be configured concurrently for both
802.1X and Web/MAC authentication. This fix will not allow concurrent configuration of an
unauth-vid for the aaa port-access authenticator and aaa port-access web-based or aaa port-
access mac-based functions. Software versions that contain this fix will not allow the this
configuration conflict at the CLI. Existing configurations will be altered by this fix, and an
error will be reported at the switch CLI and event log.
Best Practice Tip: 802.1X should not have an unauthenticated VLAN setting when it works
concurrently with Web-based or MAC-based authentication if the unauth-period in 802.1X is zero
(the default value). Recall that the unauth-period is the time that 802.1X will wait for authenti-
cation completion before the client will be authorized on an unauthenticated VLAN. If 802.1X is
associated with an unauthenticated VLAN when the unauth-period is zero, Web- or MAC-auth
may not get the opportunity to initiate authentication at all if the first packet from the client is
an 802.1X packet. Alternatively, if the first packet sent was not 802.1X, Web- or MAC-auth could
be initiated before 802.1X places the user in the unauthenticated VLAN and when Web- or MAC-
auth completes successfully, it will be awaiting traffic (to enable VLAN assignment) from the
client but the traffic will be restricted to the unauthenticated VLAN, and thus the client will
remain there.
If a MAC- or Web-based configuration on a port is associated with an unauth-VID, and an attempt
is made to configure an unauth-VID for 802.1X (port-access authenticator), the switch with this
fix will reject the configuration change with a message similar to one of the following.
Message 1 (when an unauth-vid config is attempted on a port with an existing Web- or MAC-auth
unauth-vid):
Configuration change denied for port <number>.Only Web or MAC-
authenticator can have unauthenticated VLAN enabled if 802.1X
authenticator is enabled on the same port. Please disable Web and
MAC authentication on this port using the following commands:
"no aaa port-access web-based <PORT-LIST>" or
"no aaa port-access mac-based <PORT-LIST>"
Then you can enable 802.1X authentication with unauthenticated VLAN.
You can re-enable Web and/or MAC authentication after you remove the
unauthenticated VLAN from 802.1X.Note that you can set unauthenti-
cated VLAN for Web or MAC authentication instead.

Message 2 (when an unauth-vid config is attempted on a port with an existing 802.1X unauth-vid):
Configuration change denied for port <number>.Only Web or MAC-
authenticator can have unauthenticated VLAN enabled if 802.1X
authenticator is enabled on the same port. Please remove the
unauthenticated VLAN from 802.1X authentication on this port using
the following command:
"no aaa port-access authenticator <PORT-LIST> unauth-vid"
Note that you can set unauthenticated VLAN for Web or MAC
authentication instead.
Message 3:
Configuration change denied for port <number>. Only Web or MAC-
authenticator can have unauthenticated VLAN enabled if 802.1X
authenticator is enabled on the same port. Please use unauthenticated
VLAN for Web or MAC authentication instead.
Event log message when the configuration is changed:
mgr: Disabled unauthenticated VLAN on port <number> for the 802.1X.
Unauthenticated VLAN cannot be simultaneously enabled on both 802.1X
and Web or MAC authentication.
