Support for Internet Group Management Protocol (IGMP) snooping for multicasting
Support for Uplink Failure Detection (UFD) for network path resiliency. It works in conjunction with NIC teaming
functionality that is supported on the blade servers. This feature tracks the link state on uplink ports. When an
uplink port goes down or is in STP blocking state, this feature will enable the switch to auto-disable the
downlinks which are connected to the blade server NICs. This enables NIC teaming software to detect link
failure on the primary NIC port and fail over to the secondary NIC in the team. As a result, the secondary path
is enabled for continued blade server access.
When used in conjunction with UFD, NIC teams on the blade server must be configured for switch redundancy.
That is, the team will span ports on both Switch A and Switch B. Refer to the HP ProLiant Network Adapter

GbE2 Interconnect Switch architecture
The ProLiant BL p-Class system provides integrated switching technology for network cable reduction.
The following diagram illustrates the Ethernet signal connectivity between server bays and the interconnect bays
through the backplane for the p-Class server enclosure.

through the backplane for p-Class server enclosures with enhanced backplane components that support high-density
blade servers.

The interconnect switch does not affect or determine NIC enumeration and the associated mapping of NIC interfaces
to interconnect switch ports. The numbering of the NICs on the server (for example, NIC 1, NIC 2, NIC 3) is
determined by the server type, the server operating system, and what NICs are enabled on the server.

HP Ethernet Connectivity Mapper utility (hpecm)
The HP Ethernet Connectivity Mapper is a utility used to determine the NIC name enumeration and the associated
mapping to switch ports. The physical connections between server blade network interface controllers (NICs) and
switch ports depend on the server blade type and the enclosure backplane type, as described above. The logical NIC
name enumeration depends on the operating system software (such as Local Area Connection, Local Area
Connection 2, etc. for Windows; eth0, eth1, etc. for Linux).
hpecm is a graphical tool which collects information about the contents of a ProLiant BL blade enclosure, including
enclosure type, blade type, and blade operating system (OS). It then displays the mapping between the switch or
patch panel ports and the OS enumeration (naming order) of the blade network interface controller (NIC) ports.
Configuration validation is performed as items are selected, so hpecm may also be used as an aid to configuration
and/or deployment planning.

GbE2 Interconnect Switches
Two GbE2 Interconnect Switches in the ProLiant BL p-Class server blade enclosure provide switch redundancy and
redundant paths to the network ports on the server blades. Each GbE2 Interconnect Switch has six external Ethernet
ports and sixteen internal Gigabit Ethernet ports providing connectivity to the blade servers within the enclosure.
Each pair of GbE2 Interconnect Switches consolidates up to thirty-two 10/100/1000 Ethernet signals into one-to-
eight Gigabit ports (on the back of the system) plus four additional Gigabit Ethernet ports (on the front of the GbE2
Interconnect Switches). This design eliminates up to 31 network cables from the back of the server blade enclosure.
Redundant crosslinks
The two GbE2 Interconnect Switches are connected through redundant 10/100/1000 crosslinks. These two
crosslinks provide an aggregate throughput of 2 Gb/s for traffic between the GbE2 Interconnect Switches.
Redundant paths to server bays
Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate GbE2
Interconnect Switches within the enclosure. Two Ethernet signals are routed to Switch A and two are routed to Switch
B. This configuration provides redundant paths to each server bay.
Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate GbE2
Interconnect Switches within the enclosure. However, specific switch port to server mapping varies depending on
which type of server blade is installed. For example, for ProLiant BL20p series servers, two Ethernet signals are routed
to Switch A and two are routed to Switch B. This configuration provides redundant paths to each server bay.
On a heavily used system, using a single uplink port for 32 Ethernet signals can cause a traffic bottleneck. For
optimum performance, HP recommends that at least one uplink port per GbE2 Interconnect Switch be used.
The two front panel 10Base-T/100Base-TX/1000Base-T ports per GbE2 Interconnect Switch may also be used for
additional uplink bandwidth to the network.
Supported technologies
The ProLiant BL p-Class GbE2 Interconnect Switch supports the following technologies.
Layer 2 switching
The ProLiant BL p-Class GbE2 Interconnect Switch uses 10/100/1000 Gigabit Layer 2 switching technology. Layer 2
refers to the Data Link layer of the Open Systems Interconnection (OSI) model, which is concerned with moving data
packets across a network by enforcing Carrier Sense Multiple Access with Collision Detection (CSMA/CD). This layer
performs the following tasks:
•
•
•
•
•
Ethernet packet framing
Medium Access Control (MAC) addressing
Physical medium transmission error detection
Medium allocation (collision avoidance)
Contention resolution (collision handling)
Introduction 12
Download from Www.Somanuals.com. All Manuals Search And Download.
Layer 2 switching technology allows the GbE2 Interconnect Switch to look into data packets and redirect them based
on the destination MAC address. This reduces traffic congestion on the network because packets, instead of being
transmitted to all ports, are transmitted to the destination port only.
IEEE 802.1Q-based Virtual Local Area Network
The ProLiant BL p-Class GbE2 Interconnect Switch provides support for a total of 255 IEEE 802.1Q Virtual Local Area
Networks (VLANs) for server grouping and isolation. A VLAN is a network segment configured according to a logical
scheme rather than a physical layout. VLANs can be used to combine any collection of local area network (LAN)
segments into an autonomous user group that appears as a single LAN.
VLANs also logically segment the physical network into different broadcast domains so that packets are forwarded
only between ports within the VLAN. This technology enhances performance by conserving bandwidth and improves
security by limiting traffic to specific domains. For example, you may want to isolate the server blade iLO ports from
the rest of the NICs. The iLO ports on interconnect Switch B can be assigned to their own VLAN and go to a
dedicated uplink or share an uplink using VLAN tagging.
IMPORTANT: The greater the number of VLANs, the greater the GbE2 Interconnect Switch central processing
unit (CPU) utilization. For maximum interconnect switch performance, HP recommends that you be judicious
when configuring the number of VLANs.
Spanning Tree Protocol
The GbE2 Interconnect Switch supports IEEE 802.1D Spanning Tree Protocol (STP), which allows the blocking of links
that form loops between switches in a network. When multiple links between switches are detected, a primary link is
established. Duplicated links are blocked from use and become standby links. If the primary link fails, the standby link
is activated.
In addition, the GbE2 Interconnect Switch provides a spanning tree domain per VLAN. The switch is compatible with
Cisco® PVST+ and Cisco PVST, when the other device is configured as untagged or configured to use 802.1q
tagging. Sixteen spanning tree domains are supported per GbE2 Interconnect Switch.
Release 2.0 also provides IEEE 802.1s-based MSTP and IEEE 802.1w-based RSTP.
Simple Network Management Protocol
Each GbE2 Interconnect Switch can be configured and monitored remotely from a Simple Network Management
Protocol (SNMP)-based network management station. The GbE2 Interconnect Switch supports industry-standard SNMP
Management Information Bases (MIBs) and proprietary HP enterprise switch MIBs for fault detection and monitoring
of switch functionality. In addition, the GbE2 Interconnect Switch supports various environmental traps such as
temperature and fan failure traps.
To secure the management interface, the switch administrator can configure community strings with two levels of
access: Read and Read/Write. Access to the GbE2 Interconnect Switch can also be restricted to only management
stations that are members of a specific Internet Protocol (IP) network. This can be achieved by configuring the
address/mask of that specific network as a restricted management network address/mask.
Port mirroring
The GbE2 Interconnect Switch allows you to mirror one or multiple ports (source ports) to another port (destination
port) for network monitoring and troubleshooting purposes. This technology offers a way for network packet
analyzers to view the traffic moving through the GbE2 Interconnect Switches by providing a copy of the traffic that is
currently being passed through any other port. The packets are normally sent to a network packet analyzer or other
monitoring device attached to the mirror port.
Port trunking and load balancing
The GbE2 Interconnect Switch supports EtherChannel compatible IEEE 802.3ad (without LACP) port trunking allowing
several ports to be grouped together and act as a single logical link called a trunk. This feature provides a bandwidth
that is a multiple of the bandwidth of a single link. It also improves reliability since load balancing is automatically
applied to the ports in the trunked group. A link failure within the group causes the network traffic to be directed to
the remaining links in the group.
Trivial File Transfer Protocol support
Trivial File Transfer Protocol (TFTP) support allows the GbE2 Interconnect Switch firmware to be upgraded by
downloading a new firmware file from a TFTP server to the GbE2 Interconnect Switch. Firmware images of the GbE2
Introduction 13
Download from Www.Somanuals.com. All Manuals Search And Download.
Interconnect Switch can also be uploaded to a TFTP server, a configuration file can be downloaded into a GbE2
Interconnect Switch from a TFTP server, and configuration settings can be saved to the TFTP server.
Store and forward switching scheme
The GbE2 Interconnect Switch provides a store and forward switching scheme that allows each packet to be buffered
(stored) before it is forwarded to its destination. While this method creates latency, it improves reliability in a heavily
used interconnect switch. Packets that cannot be forwarded are saved immediately, rather than dropped, so that
packets behind them are less likely to be dropped in periods of heavy usage.
Bootstrap Protocol
By default, the GbE2 Interconnect Switch is configured to obtain an IP address from a Bootstrap Protocol (BOOTP)
server during the boot process. The IP settings can also be manually configured by means of the serial interface. The
IP settings are configurable from the browser-based interface, but because the connection is based on an IP address
for these interfaces, users will have to reconnect with the newly assigned IP address.
Network Time Protocol
The GbE2 Interconnect Switch can maintain the current date and time. This information displays on the management
interfaces and is used to record the date and time of switch events. Current date and time information can be
manually set on the GbE2 Interconnect Switch or can be obtained through Network Time Protocol (NTP). NTP allows
the GbE2 Interconnect Switch to send a request to a primary NTP server in each polling period asking for Greenwich
Mean Time (GMT).
Remote Authentication Dial-in User Service (RADIUS)
The GbE2 Interconnect Switch supports the Remote Authentication Dial-in User Service (RADIUS) method to
authenticate and authorize remote administrators for managing the GbE2 Interconnect Switch. This method is based
on a client/server model. The Remote Access Server (RAS)—the switch—is a client to the back-end database server. A
remote user (the remote administrator) interacts only with the RAS, not the back-end server and database.
RADIUS authentication consists of the following components:
•
A protocol with a frame format that utilizes User Datagram Protocol (UDP) over IP, based on Request For
Comments (RFC) 2138 and 2866
•
•
A centralized server that stores all the user authorization information
A client, in this case, the GbE2 Interconnect Switch
The GbE2 Interconnect Switch, acting as the RADIUS client, communicates to the RADIUS server to authenticate and
authorize a remote administrator using the protocol definitions specified in Request For Comments (RFC) 2138 and
2866. Transactions between the client and the RADIUS server are authenticated using a shared key that is not sent
over the network. In addition, the remote administrator passwords are sent encrypted between the RADIUS client (the
switch) and the back-end RADIUS server.
The benefits of using RADIUS are:
•
•
•
•
Authentication of remote administrators
Identification of the administrator using name/password
Authorization of remote administrators
Determination of the permitted actions and customizing service for individual administrators
Terminal Access Controller Access Control System Plus (TACACS+)
Starting with Release 2.0, the GbE2 Interconnect Switch supports the Terminal Access Controller Access Control
System Plus (TACACS+) method to authenticate, authorize, and account for remote administrators managing the
GbE2 Interconnect Switch. This method is based on a client/server model. The switch is a client to the back-end
TACACS+ AAA server. A remote user (the remote administrator) interacts only with the client, and not with the
back-end AAA server.
The TACACS+ AAA method consists of the following components:
•
•
A protocol with a frame format that utilizes TCP over IP
A centralized AAA server that stores all the user authentication, authorization, and accounting (of usage)
information
•
A Network Access Server (NAS) or client (in this case, the GbE2 Interconnect Switch)
The GbE2 Interconnect Switch, acting as the TACACS+ client or NAS, communicates to the TACACS+ server to
authenticate, authorize, and account for user access. Transactions between the client and the TACACS+ server are
Introduction 14

authenticated using a shared key that is not sent over the network. In addition, the remote administrator passwords
are sent encrypted between the TACACS+ client (the switch) and the back-end TACACS+ server.
The GbE2 Interconnect Switch supports:
•
•
•
Only standard ASCII inbound login authentication. PAP, CHAP, or ARAP login methods are not supported. One-
time password authentication is also not supported.
Authorization privilege levels of only 0, 3, and 6. These map to management levels of user, oper, and admin,
respectively.
The accounting attributes of protocol, start_time, stop_time, and elapsed_time. For WebUI (BBI) users,
accounting stop records are only sent if the user presses the QUIT button.
Secure Shell and Secure Copy
Secure Shell (SSH) and Secure Copy (SCP) use secure tunnels to encrypt and secure messages between a remote
administrator and the GbE2 Interconnect Switch. Telnet does not provide this level of security. The Telnet method of
managing a GbE2 Interconnect Switch does not provide a secure connection.
SSH is a protocol that enables remote administrators to log securely into the GbE2 Interconnect Switch over a network
to execute management commands.
SCP is typically used to copy files securely from one machine to another. SCP uses SSH for encryption of data on the
network. On a GbE2 Interconnect Switch, SCP is used to download and upload the switch configuration via secure
channels.
XModem
The GbE2 Interconnect Switch supports XModem for transferring files during direct dial-up communications. XModem
sends blocks of data in 128-byte blocks, and includes an error-detection system called a checksum. When the data is
received, the error detection system ensures that the entire message reached its destination. If not, the receiving
computer sends a request for retransmission of the data.
Internet Group Management Protocol (IGMP) Snooping
The GbE2 Interconnect Switch supports IGMP Snooping for multicasting, starting with Release 2.0. Both Version 1-
and Version 2-based IGMP Snooping is supported. In addition, auto detection of the multicast router port and manual
configuration of the multicast router port is supported. For efficient multicast traffic management, the IGMP Filtering
option is supported.
Jumbo frames
By default, the GbE2 Interconnect Switch module supports jumbo frames up to 9216 bytes, which may help reduce
server central processing unit (CPU) utilization and may increase application throughput. No configuration is
required. The GbE2 Interconnect Switch does not fragment frames as they exit, or assemble packets into jumbo
frames as they enter the switch.
Auto-MDI/MDIX
The GbE2 Interconnect Switch Ethernet ports are medium dependent interface (MDI)/MDI crossover (MDIX) capable.
MDI/MDIX is a type of Ethernet port connection using twisted pair cabling. The medium dependent interface (MDI) is
the component of the media attachment unit (MAU) that provides the physical and electrical connection to the cabling
medium. An MDI crossover (MDIX) is a version of MDI that enables connection between like devices. MDI ports
connect to MDIX ports via straight-through twisted pair cabling whereas both MDI-to-MDI and MDIX-to-MDIX
connections use crossover twisted pair cabling. The GbE2 Interconnect Switch has the capability to automatically
detect the cable selection/type, making the distinction between a straight-through cable and a crossover cable
unimportant.
Auto-negotiation of duplex mode and speed
Auto-negotiation of duplex mode and speed can be configured on the GbE2 Interconnect Switch. Network adapters
that support multiple data speeds, such as Fast Ethernet and Gigabit Ethernet, choose the speed at which they run
through a procedure called auto-negotiation. Auto-negotiation involves probing the capability of the network using
low-level signaling techniques to select compatible Ethernet speeds. Auto-negotiation was originally developed to
make the migration from traditional Ethernet to Fast Ethernet products easier.

Redundant images in firmware
The GbE2 Interconnect Switch can store up to two different software images, called image1 and image2, as well as
boot software, called boot. When you download new software, you are given the ability to specify where it is to be
placed: either into image1, image2, or boot.
For example, if your active image is currently loaded into image1, you should probably load the new image software
into image2. This lets you test the new software and revert back to the original image stored in image1, if needed.
CAUTION: Unlike the firmware that has two images, there is only one image of boot supported. Upgrading the
boot image replaces the original boot image.

The HP ProLiant BL p-Class GbE2 Storage Connectivity Kit option provides ProLiant BL20p G2 Fibre Channel signal
pass-through connectivity for the HP ProLiant BL p-Class C-GbE2 and F-GbE2 Interconnect Kits. The GbE2 Storage
Connectivity Kit may be ordered separately and installed during a new deployment or later as an upgrade.
The GbE2 Storage Connectivity Kit contains two ProLiant BL p-Class OctalFC Interconnect Modules that are inserted
into the top-left-most and top-right-most bays on the rear side of the server blade enclosure. Two ProLiant BL p-Class
Fibre Channel Signal Conditioning Cards are also included in the kit; one is installed in each GbE2 Interconnect
Switch.
If you are installing the GbE2 Storage Connectivity Kit, refer to the HP ProLiant BL p-Class GbE2 Storage Connectivity
Kit Quick Setup Instructions included with the GbE2 Storage Connectivity Kit for more information.
Installation guidelines
Observe the following guidelines:
•
Always install GbE2 Interconnect Switches in pairs. Each server blade enclosure requires two GbE2 Interconnect
Switches for proper connectivity. Both GbE2 Interconnect Switches are identical. They get their identities (Switch
A or Switch B) from the server blade enclosure slots they are plugged into.
•
•
For proper operation, you must run like pairs in the interconnect slot.
Always install the QuadT2 or QuadSX Interconnect Modules into the bottom-left-most and bottom-right-most bays
on the rear side of the server blade enclosure.
•
•
Be sure that each interconnect module is fully seated. The latch/handle will drop into place when the module is
firmly seated.
Always install the GbE2 Interconnect Switches into the interconnect bays, which are the left-most (side A) and
right-most (side B) bays on the front side of the server blade enclosure.
IMPORTANT: Record the switch MAC address printed on the MAC address label attached to your GbE2
Interconnect Switch. The MAC address can be used to find the IP address from a BOOTP server.

Replacing an existing GbE2 Interconnect Switch
CAUTION: Removing a GbE2 Interconnect Switch from a powered enclosure will result in the loss of network
communications between the server blade network ports that are connected through this switch and the
segment of network infrastructure those ports need to communicate.
For continued blade server network communication and services availability, do the following before you
remove the GbE2 Interconnect Switch. Redirect critical high-availability services or applications to use the
redundant network ports available on those blade servers that are connected through the redundant GbE2
Interconnect Switch in the enclosure.

IMPORTANT: If you are replacing an existing GbE2 Interconnect Switch, or upgrading from a GbE
Interconnect Switch, an RJ-45 Patch Panel, or an RJ-45 Patch Panel 2, and you have strict security requirements:
Do not cable the GbE2 Interconnect Switch until after configuration.
Or
Connect the GbE2 Interconnect Switch to the optional Diagnostic Station. The Diagnostic Station enables you
to power up, configure, and diagnose a ProLiant p-Class server blade or a ProLiant p-Class GbE2 Interconnect
Switch outside of the rack environment.
To replace an existing GbE2 Interconnect Switch:
1.
If possible, save the configuration file to a TFTP server for later retrieval. For more information on saving a
configuration file to a TFTP server, refer to the HP ProLiant BL p-Class GbE2 Interconnect Switch Command
Reference Guide.
2.

If you saved the configuration file to a TFTP server, download the configuration. For more information on
downloading a configuration file, refer to the HP ProLiant BL p-Class GbE2 Interconnect Switch Command
Reference Guide.
NOTE: Only replace the interconnect module if it is faulty, or if a different type of interconnect module is
required.
Upgrading from an existing GbE Interconnect Switch
CAUTION: Removing a GbE Interconnect Switch from a powered enclosure will result in the loss of network
communications between the server blade network ports that are connected through this switch and the
segment of network infrastructure those ports need to communicate.
For continued blade server network communication and services availability, do the following before you
remove the GbE Interconnect Switch. Redirect critical high-availability services or applications to use the
redundant network ports available on those blade servers that are connected through the redundant GbE
Interconnect Switch in the enclosure.

Or
Connect the GbE2 Interconnect Switch to the optional Diagnostic Station. The Diagnostic Station enables you
to power up, configure, and diagnose a ProLiant p-Class server blade or a ProLiant p-Class GbE2 Interconnect
Switch outside of the rack environment.
IMPORTANT: By default, both the GbE Interconnect Switch and GbE2 Interconnect Switch have STP enabled
and have X-Connect ports (17 and 18) bundled in to a port trunk. During an upgrade from a GbE Interconnect
Switch to a GbE2 Interconnect Switch, there will be an STP convergence delay due to the topology change.
This causes a temporary interruption to packet forwarding on the attached Layer 2 switching network.

GbE2 Interconnect Switch into the left interconnect bay.
Upgrading from an RJ-45 Patch Panel or RJ-45 Patch Panel 2
CAUTION: Removing a patch panel from a powered enclosure will result in the loss of network
communications between the server blade network ports that are connected through this patch panel and the
segment of network infrastructure those ports need to communicate.
IMPORTANT: If you are replacing an existing GbE2 Interconnect Switch, or upgrading from a GbE
Interconnect Switch, an RJ-45 Patch Panel, or an RJ-45 Patch Panel 2, and you have strict security requirements:
Do not cable the GbE2 Interconnect Switch until after configuration.
Or
Connect the GbE2 Interconnect Switch to the optional Diagnostic Station. The Diagnostic Station enables you
to power up, configure, and diagnose a ProLiant p-Class server blade or a ProLiant p-Class GbE2 Interconnect

6.
Lock the ejector levers.
Repeat steps 4 and 5 to install the second GbE2 Interconnect Switch in the right interconnect bay.
Planning the GbE2 Interconnect Switch configuration
Before you configure the GbE2 Interconnect Switch, HP recommends that you plan the configuration. As you plan,
consider your default settings, security issues and privileges, and whether you want to configure each GbE2
Interconnect Switch manually or configure multiple GbE2 Interconnect Switches at the same time.
Default settings
The GbE2 Interconnect Switches ship with a default configuration in which all ports are enabled and assigned a
default VLAN with a VLAN ID (VID) equal to 1. This default configuration simplifies your initial setup by allowing you
to use a single uplink cable (from any external Ethernet connector) to connect your server blade enclosure to your
network. You need to assess your particular server environment to determine any requirements for other
considerations.
When planning the configuration, consider the default settings for the following parameters:
•
•
•
•
•
•
•
Switch IP settings
Virtual Local Area Network (VLAN) settings
Spanning Tree Protocol (STP) settings
Port names and types
Port trunking settings
Interswitch X-Connect port settings
Simple Network Management Protocol (SNMP) settings

•
•
User name and password settings
Default access to various management interfaces
Network Time Protocol (NTP) settings
IMPORTANT: Refer to the “Runtime switching software default settings” appendix for a complete list of default
configuration settings.
GbE2 Interconnect Switch security
When planning the GbE2 Interconnect Switch configuration, secure access to the management interface by:
•
•
•
Creating users with various access levels
Enabling or disabling access to various management interfaces to fit the security policy
Changing default SNMP community strings for read-only and read-write access
User, operator, and administrator access rights
To enable better GbE2 Interconnect Switch management and user accountability, three levels or classes of user access
have been implemented on the GbE2 Interconnect Switch. Levels of access to CLI, Web management functions, and
screens increase as needed to perform various GbE2 Interconnect Switch management tasks. Conceptually, access
classes are defined as follows:
•
User interaction with the GbE2 Interconnect Switch is completely passive; nothing can be changed on the GbE2
Interconnect Switch. Users may display information that has no security or privacy implications, such as GbE2
Interconnect Switch statistics and current operational state information.
•
Operators can only effect temporary changes on the GbE2 Interconnect Switch. These changes will be lost
when the GbE2 Interconnect Switch is rebooted/reset. Operators have access to the GbE2 Interconnect Switch
management features used for daily GbE2 Interconnect Switch operations. Because any changes an operator
makes are undone by a reset of the GbE2 Interconnect Switch, operators cannot severely impact GbE2
Interconnect Switch operation.
•
Administrators are the only ones that may make permanent changes to the GbE2 Interconnect Switch
configuration, changes that are persistent across a reboot/reset of the GbE2 Interconnect Switch. Administrators
can access GbE2 Interconnect Switch functions to configure and troubleshoot problems on the GbE2
Interconnect Switch. Because administrators can also make temporary (operator-level) changes as well, they
must be aware of the interactions between temporary and permanent changes.
Access to GbE2 Interconnect Switch functions is controlled through the use of unique surnames and passwords. Once
you are connected to the GbE2 Interconnect Switch via the local console, Telnet, or SSH, you are prompted to enter a
password. The default user names/password for each access level is listed in the following table.
NOTE: It is recommended that you change default GbE2 Interconnect Switch passwords after initial
configuration and as regularly as required under your network security policies. For more information, refer to
the “Setting Passwords” section in Chapter 3 of the HP ProLiant BL p-Class GbE2 Interconnect Switch
Command Reference Guide.

Manually configuring a GbE2 Interconnect Switch
A GbE2 Interconnect Switch can be configured manually using a command line interface, a browser-based interface,
or an SNMP interface. Refer to the HP ProLiant BL p-Class GbE2 Interconnect Switch Command Reference Guide for
more information on how to use these management interfaces to configure the GbE2 Interconnect Switch.
After a GbE2 Interconnect Switch is configured, you can back up the configuration as a text file to a TFTP server. The
backup configuration file can then be downloaded from the TFTP server to restore the switch back to the original
configuration. This restoration may be necessary under one of the following conditions:
•
•
The switch configuration becomes corrupted during operation.
The switch must be replaced because of a hardware failure.
Configuring multiple GbE2 Interconnect Switches
You can configure multiple GbE2 Interconnect Switches by using scripted command line interface (CLI) commands
through Telnet or by downloading a configuration file using a TFTP server.
Using scripted CLI commands through Telnet
The CLI, provided with the GbE2 Interconnect Switch, allows you to execute customized configuration scripts on
multiple switches. A configuration script can be tailored to one of the multiple switches, and then that configuration
can be deployed to other switches from a central deployment server.
Using a configuration file
If you plan for the base configuration of multiple GbE2 Interconnect Switches in your network to be the same, you can
manually configure one GbE2 Interconnect Switch, upload the configuration to a TFTP server, and use that
configuration as a base configuration template file.
GbE2 Interconnect Switch IP addresses are acquired by default using BOOTP, therefore, each GbE2 Interconnect
Switch has a unique IP address. Each GbE2 Interconnect Switch can be remotely accessed from a central deployment
server and an individual interconnect switch configuration can be downloaded to meet specific network requirements.
Refer to the HP ProLiant BL p-Class GbE2 Interconnect Switch Command Reference Guide for additional information
on using a TFTP server to upload and download configuration files.
Cabling the GbE2 Interconnect Switch
After installing the GbE2 Interconnect Switch hardware and planning the configuration, cable the GbE2 Interconnect
Switch to your network.
IMPORTANT: If you are replacing an existing GbE2 Interconnect Switch, or upgrading from a GbE
Interconnect Switch, an RJ-45 Patch Panel, or an RJ-45 Patch Panel 2, and you have strict security requirements:
Do not cable the GbE2 Interconnect Switch until after configuration.
Or
Connect the GbE2 Interconnect Switch to the optional Diagnostic Station. The Diagnostic Station enables you
to power up, configure, and diagnose a ProLiant p-Class server blade or a ProLiant p-Class GbE2 Interconnect
Switch outside of the rack environment.
Setting up and installing the GbE2 interconnect switch 26

Figure 14 Installing the cable-retaining bracket
5.
Repeat steps 2 through 4 for the network cables on the left side of the rack.
Powering up the GbE2 Interconnect Switch
If the server blade enclosure has power applied, the GbE2 Interconnect Switch automatically begins to power up
when installed. The power status LED on the front of the GbE2 Interconnect Switch starts out as amber to indicate that
power is connected to the GbE2 Interconnect Switch. After 30 seconds, the power status LED turns to green to
indicate that the GbE2 Interconnect Switch is powered up. After the built in self-test flashes all LEDs, the active links
are illuminated, and the power status LED stays green.
You can manually force the GbE2 Interconnect Switch to power up by pressing the Pwr/Rst button through the access
hole in the front panel of the GbE2 Interconnect Switch while the power status LED is amber. HP recommends using a
small blunt object for this purpose.
CAUTION: Pressing the Pwr/Rst button while the power status LED is green will reset the GbE2 Interconnect
Switch.
IMPORTANT: If the server blade enclosure does not have power applied, refer to the system setup and
installation guide for the server blade enclosure.
Accessing the GbE2 Interconnect Switch
The GbE2 Interconnect Switch can be accessed using the serial (DB-9) management port or an Ethernet connection.
•
•
To access the GbE2 Interconnect Switch locally, use the front panel serial management port.
To access the GbE2 Interconnect Switch through an Ethernet connection, use either the GbE2 Interconnect
Switch front panel RJ-45 ports or one of the following:
•
•
The uplink RJ-45 ports in the QuadT2 Interconnect Module
The uplink LC fiber ports in the QuadSX Interconnect Module
To access the GbE2 Interconnect Switch via an Ethernet connection, you need to assign it an IP address. By default,
the GbE2 Interconnect Switch is set up to obtain its IP address from a BOOTP server existing on the attached network.
1.
Access the BOOTP server and use the GbE2 Interconnect Switch MAC address to obtain the switch IP address.
The MAC address is printed on the MAC address label attached to the GbE2 Interconnect Switch.

2.
From a computer connected to the same network, use the IP address to access the GbE2 Interconnect Switch
using a Web browser or Telnet application. This allows you to access the GbE2 Interconnect Switch browser-
based interface (BBI) or command line interface (CLI). Once you have accessed the GbE2 Interconnect Switch,
the GbE2 Interconnect Switch logon prompt is displayed.
If the GbE2 Interconnect Switch does not obtain the IP address by means of the BOOTP service, you can access the
switch locally and manually assign an IP address.
1.
Connect the GbE2 Interconnect Switch DB-9 serial connector, using the null-modem cable (provided with the
following option kits: Scalable Busbar, Mini Busbar, and Power Bus Box), to a local client device (such as a
laptop computer) with VT100 terminal emulation software (such as Microsoft® Windows® HyperTerminal).
2.
3.
Open a VT100 terminal emulation session with the following settings: 9600 baud rate, eight data bits, no
parity, one stop bit, and no flow control.
Complete the following instructions to log on and configure the GbE2 Interconnect Switch. Once you have
assigned an IP address, you can access the switch remotely.

SNMP MIBs support
Introduction
Management and statistics information is stored in the GbE2 Interconnect Switch in the Management Information Base
(MIB). The GbE2 Interconnect Switch supports several standard MIBs. Values for MIB objects can be retrieved with
any SNMP-based network management software.
In addition to the standard MIBs, the switch also supports its own proprietary enterprise MIB as an extended
Management Information Base. The proprietary MIB is retrieved by specifying the MIB Object-Identifier (OID) at the
network manager station.
MIB values can be either read-only or read/write variables.
•
Read-only MIB variables can be constants that are programmed into the switch or variables that change while
the switch is in operation. Examples of read-only constants include the number and types of ports. Examples of
read-only variables are the statistics counters, such as the number of errors that have occurred or how many
kilobytes of data have been received and forwarded through a port.
•
Read/write MIB variables are usually related to user-customized configurations. Examples include the IP address
of the switch, Spanning Tree Algorithm parameters, and port status.
SNMP manager software
If you use third-party vendor SNMP software to manage the switch, you can access proprietary enterprise MIBs for the
If your software provides functions to browse or modify MIBs, you can also change the MIB values (if the MIB
attributes permit the write operation). This process can be quite involved, because you must use the MIB OIDs,
available in the MIB files, and retrieve them one by one.
Use an SNMP manager, such as HP OpenView Network Node Manager or HP Systems Insight Manager, to access
the enterprise-specific MIBs. Compile the MIBs into the MIB database and then use a MIB browser to navigate through
them. For detailed information, access the individual descriptions of each MIB or refer to the documentation that came
with your SNMP manager software.
The GbE2 Interconnect Switch SNMP agent supports SNMP Version 1. Security is provided through SNMP community
strings. The default community strings are “public” for SNMP GET operation and “private” for SNMP SET operation.
Users may specify up to two trap hosts for receiving SNMP traps. The agent will send the SNMP trap to the specified
hosts when appropriate. Traps will not be sent if there is no host specified.
Supported MIBs
The SNMP agent for the GbE2 Interconnect Switch supports the following MIBs:
•
•
bt2Network.mib— Layer 3 configuration information including IP interface, gateway, Domain Name System
(DNS), IGMP, and static Mrouter
bt2Physical.mib— Layer 2 configuration information including VLAN, trunk groups, spanning tree
configuration, port mirroring, Forwarding Database (FDB) table, MSTP/RSTP, and Uplink Failure Detection

Safe Mode configuration
Introduction
GbE2 Interconnect Switch configuration files are specified in text format. Trivial File Transfer Protocol (TFTP) or Secure
Copy (SCP) services can to be used to upload and download these text-based configuration files. When these
configuration files are downloaded and applied to the GbE2 Interconnect Switch, the GbE2 Interconnect Switch
interprets the contents and applies it to the system as active configuration.
The configuration settings can be saved to NVRAM, and they become the backup configuration for the GbE2
Interconnect Switch. These settings are then used every time the GbE2 Interconnect Switch is rebooted.
IMPORTANT: The TFTP server must be running TFTP server software to perform a file transfer. TFTP server
software is included as part of the Windows utilities package.
When inserting a new or replacement GbE2 Interconnect Switch into a production/real-time environment, you must
be certain that the GbE2 Interconnect Switch configuration is compatible with the production network. Since the
factory default switch configuration may not be same as the production configuration, it may compromise the security
aspects and VLAN isolation used by the production network.
A new or replacement GbE2 Interconnect Switch should be preconfigured in a "safe mode" such that it addresses
these security concerns and still allows the administrator to configure the switch and finalize switch deployment on the
production network. The administrator can simply download a final configuration template with the safe mode
configuration to deploy the GbE2 Interconnect Switch in the production environment.
User account information
User password information is not saved in the configuration file for security reasons and must be managed by the
GbE2 Interconnect Switch administrator. User account information can be manually added to the configuration file
after it is uploaded, or it can be re-entered using the CLI.
Safe Mode
When inserting a new or replacement GbE2 Interconnect Switch into a production environment, you must be certain
that the GbE2 Interconnect Switch configuration is compatible with the production network. Compatibility with a
network can include items such as:
•
Specific configuration of the network in general—problems, such as loops, can occur within the network without
specifically enabling Spanning Tree Protocol (STP)
•
Security of connected network entities—security issues can arise as a result of configuration items, including
such attributes as subnet-to-subnet communication and blade-to-blade communication where communication
between these entities is not acceptable
•
•
Security of the GbE2 Interconnect Switch—these attributes include controlled access to the GbE2 Interconnect
Switch such as user-password and SNMP read-write community strings
Other configuration attributes, such as VLAN settings
The GbE2 Interconnect Switch factory default, as well as previously configured GbE2 Interconnect Switches, may not
have configurations that are compatible with the production network.
If the configuration of the GbE2 Interconnect Switch is not compatible with the production network, the GbE2
Interconnect Switch may be pre-configured in a pre-production network environment before inserting in to production
environment. Also, the GbE2 Interconnect Switch can booted up using the Diagnostic Station for preconfiguration, to
make it ready for production network.
There are several preconfiguration options:
•
•
Configure the GbE2 Interconnect Switch for its exact position in the production network.
Partially configure the GbE2 Interconnect Switch so that it is compatible with multiple positions in the production
network. The configuration can then be completed for the GbE2 Interconnect Switch through scripting, manual
operation, or a configuration download. This more globally appropriate configuration is called a safe mode
configuration. Note that a single safe mode configuration may or may not be appropriate for all production
environments. A spare GbE2 Interconnect Switch, however, configured to a safe mode, may be appropriate for
multiple production environments.

configuration
When an in-production GbE2 Interconnect Switch fails:
1.
2.
3.
4.
Remove the failed GbE2 Interconnect Switch.
Insert the spare GbE2 Interconnect Switch that was previously configured for safe operation.
Upgrade to new firmware if appropriate.
Download the correct configuration for that particular GbE2 Interconnect Switch.
Safe Mode configuration file templates
An example template configuration file, named Safe_Mode_GbE2, has been provided as a basis to create an
appropriate safe mode configuration. This file, delivered with the GbE2 Interconnect Switch Management Utilities
package, is located on the utilities and user documentation CD included in the interconnect kit and at
NOTE: The template provided is only an example, and should not be used in a production environment without
modifications required for your specific production network. This template has commented sections such as for
IP configuration, password protection, and port selection.
Safe Mode configuration file template modification
To modify the safe mode configuration file template:
1.
2.
3.
Review the readmefile.
Copy the example safe mode template to a new file with custom name.
Perform modifications appropriate for your production environment. Your environment may require additional
settings such as VLAN configuration, IP settings, password settings, TFTP/SCP settings, and so on.
Applying the Safe Mode template configuration file
Use one of the following methods to apply the file to your GbE2 Interconnect Switch and set the switch in Safe Mode.
Method 1: Via the switch serial port using command line interface (CLI)
1.
2.
3.
Power up the switch using the Diagnostic Station or by inserting the switch in a non-production blade enclosure.
Log in to the switch CLI via the serial console as Admin.
Open the Safe_Mode_GbE2 template configuration file using any text editor, such as Microsoft WordPad,
and make the changes as suggested by the comments in that template configuration file.
Copy all the content from the template configuration file with your edits and paste it as a command to the switch
CLI.
4.
5.
6.
Issue the /applycommand on the CLI.
Issue the /savecommand, and type ywhen prompted.
Power up the switch by inserting it into a production blade enclosure. This boots up the switch in Safe Mode,
with all ports except uplink port 19 disabled.
7.

Electrostatic discharge
Overview
To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or
handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other
static-sensitive devices. This type of damage may reduce the life expectancy of the device.
To prevent electrostatic damage, observe the following precautions:
•
•
•
•
•
Avoid hand contact by transporting and storing products in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
Place containers on a grounded surface before removing the contents.
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive component or assembly.
Grounding methods
There are several methods for grounding. Use one or more of the following methods when handling or installing
electrostatic-sensitive parts:
•
Use a wrist strap connected by a grounded cord. Wrist straps are flexible straps with a minimum of 1 megohm
10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
•
Use heel straps, toe straps, or boot straps. Wear the straps on both feet when standing on conductive floors or
dissipating floor mats.
•
•
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an HP authorized reseller install the
part.
NOTE: For more information on static electricity or assistance with product installation, contact your HP
authorized reseller.
