(default) TFTP option.

•

Use the copy tftp command in the switch’s CLI (see below).

■

For an Xmodem transfer from a PC or Unix workstation, do either of the following:

•

Click on Download OS in the Main Menu of the switch’s menu interface and select the

Xmodem option.

•

Use the copy xmodemcommand in the switch’s CLI (page 4).

■

Use the download utility in ProCurve Manager Plus.

A switch-to-switch file transfer

N o t e

Downloading new software does not change the current switch configuration. The switch configu-

ration is contained in a separate file that can also be transferred, for example, for archive purposes

or to be used in another switch of the same model.

This section describes how to use the CLI to download software to the switch. You can also use the

menu interface for software downloads.

Downloading Software to the Switch

TFTP Download from a Server

Syntax: copy tftp flash <ip-address> <remote-os-file> [< primary | secondary >]

Note that if you do not specify the flash destination, the TFTP download defaults to the primary flash.

For example, to download a software file named R_11_04.swi from a TFTP server with the IP address

of 10.28.227.103:

1. Execute the copy command as shown below:

ProCurve # copy tftp flash 10.28.227.103 R_11_04.swi

The primary OS image will be deleted. continue [y/n]? Y

03125K

2. When the switch finishes downloading the software file from the server, it displays the progress

message:

Validating and Writing System Software to FLASH.

When the CLI prompt re-appears, the switch is ready to reboot to activate the downloaded

software

3. 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.

Downloading Software to the Switch

Xmodem Download From a PC or Unix Workstation

This procedure assumes that:

■

The switch is connected via the Console RS-232 port on a PC operating as a terminal. (Refer to

the Installation Guide you received with the switch for information on connecting a PC as a

terminal and running the switch console interface.)

■

The switch software is stored on a disk drive in the PC.

The terminal emulator you are using includes the Xmodem binary transfer feature. (For example,

in the Microsoft Windows NT® terminal emulator, you would use the Send File option in the

Transfer drop-down menu.)

Syntax:

copy xmodem flash < unix | pc >

For example, to download a software file from a PC:

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 57600 bits per second. (The baud rate must be the same in

both devices.) For example, to change the baud rate in the switch to 57600, execute this

command:

ProCurve(config)# console baud-rate 57600

(If you use this option, be sure to set your terminal emulator to the same baud rate.)

2. Execute the following command in the CLI:

ProCurve # copy xmodem flash primary

The primary OS image will be deleted. continue [y/n]? Y

Press ‘enter’ and start XMODEM on your host . . .

3. Execute the terminal emulator commands to begin the Xmodem transfer. The download can take

several minutes, depending on the baud rate used in the transfer.

4. 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.

5. Use the following command to confirm that the software downloaded correctly:

ProCurve> show system

Check the Firmware revision line to verify that the switch downloaded the new software.

6. 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.

Downloading Software to the Switch

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 “Do you

want to save current configuration [y/n]?” prompt.

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. However, the features and applications supported by your switch depend on your

particular switch model. For information on specific features supported, 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

password(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 manager command, the Menu interface Console Passwords option, 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, such as Telnet or HTTP, are plain

text protocols, which transfer passwords in open or plain text that is easily captured. To reduce the

chances of unauthorized 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.

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.

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.

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 or changing usernames, passwords, configuration, 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

SNMP Access to the Switch’s Local Username and Password Authentication MIB Objects.

A management station running an SNMP networked device management application such as

ProCurve Manager Plus (PCM+) or HP OpenView can access the switch’s management information

base (MIB) for write access to the switch’s local username and password configuration. In earlier

software versions, SNMP access to the switch’s local authentication configuration (hpSwitchAuth)

MIB objects was not allowed. However, beginning with software release U.11.04, the switch’s default

configuration allows SNMP access tothe local username and password MIB objects in hpSwitchAuth.

If SNMP access to these MIB objects is considered a security risk in your network, then you should

implement the following security precautions when downloading and booting from software release

U.11.04 or greater:

1. If SNMP write access to the switch’s local username and password authentication configuration

(hpSwitchAuth) MIB (described above is not desirable for your network, then immediately after

downloading and booting from the U.11.04 or greater software for the first time, use the

following CLI command to disable this feature:

snmp-server mib hpswitchauthmib excluded

Enforcing Switch Security

Switch Management Access Security

Note on SNMP Access to Local Authentication MIB Objects

Downloading and booting U.11.04 or later software versions for the first time enables SNMP access

to the switch’s local authentication configuration MIB objects (the default action). If SNMPv3 and

other security safeguards are not in place, the local username and password MIB objects are exposed

to unprotected SNMP access and you should use the preceding command to disable this access.

2. If you choose to leave the local authentication configuration MIB objects accessible, then you

should do the following to help ensure that unauthorized workstations cannot use SNMP tools

to change the settings:

•

Configure SNMP version 3 management and access security on the switch.

Disable SNMP version 2c on the switch.

Front-Panel Access and Physical Security

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 non-default

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.

Network Security Features

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)

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.

Network Security Features

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.

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.

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.

Enforcing Switch Security

Network Security Features

■

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.

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.
