Introduction

The ProLiant BL p-Class GbE Interconnect Switch provides provides command line, menu­driven, Simple Network Management Protocol (SNMP), and Web-based management interfaces. The command line interface (CLI) and menu-driven interface allow you to set up and control the GbE Interconnect Switch using either the serial or Ethernet ports on the switch. This guide discusses how to use the CLI to set up and manage the GbE Interconnect Switch.
The command line interface provides standard scripting capabilities as well as enhanced systems management, monitoring, and deployment. The CLI can be accessed remotely via Telnet, or locally via the RS-232 console and SLIP sessions.
For quick reference, Appendix A provides a comprehensive listing of the commands supported by the GbE Interconnect Switch CLI.

Overview

Additional References

Additional information about installing and configuring the GbE Interconnect Switch is available in the following guides, which are located on the ProLiant BL p-Class GbE Interconnect Switch Management System Utilities and User Documentation CD:
•
HP ProLiant BL p-Class GbE Interconnect Switch User Guide
•
HP ProLiant BL p-Class GbE Interconnect Switch Menu-driven Interface Reference Guide
•
HP ProLiant BL p-Class GbE Interconnect Switch Web-based Interface Reference Guide

Before You Begin

The ProLiant BL p-Class GbE Interconnect Switch supports a wide array of functions and provides flexibility and increased network performance. Some planning is required to arrive at a deployment strategy that maximizes the potential of the interconnect switch. Refer to the “Planning the GbE Interconnect Switch Configuration” section in HP ProLiant p-Class GbE Interconnect Switch User Guide for items to keep in mind as you configure your GbE Interconnect Switches.
HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide 1-1
Overview

Connecting to the GbE Interconnect Switches

You can use the command line interface by connecting the interconnect switch to a VT100-compatible terminal or a computer running an ordinary terminal emulator program (for example, the terminal program included with the Windows® operating system) using an RS-232C serial cable.
Set your terminal parameters to the following settings:
•
VT-100/ANSI compatible
•
9600 baud
•
8 data bits
•
No parity
•
One stop bit
•
No flow control
After you have set an IP address for each GbE Interconnect Switch, you can use a Telnet program (in VT100-compatible terminal mode) to access and control the switch. All of the screens are identical, whether they are accessed from the serial port or from a Telnet interface.

Logging On to the GbE Interconnect Switch

When you log on to a GbE Interconnect Switch, the following screen is displayed.
IMPORTANT: The GbE Interconnect Switch does not have any initial user names or passwords set. HP recommends that after logging on, you create at least one Root-level user as the switch administrator. (Refer to Table 2-1 in Chapter 2 for an explanation of user privileges.) If you forget your password after it has been set up, call HP Customer Support to get a MAC-based backdoor password.
1-2 HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide
Overview
To log on for the first time:
1. Leave the Username field blank and press the Tab key.
2. Leave the Password field blank and press the Enter key. The main menu for the GbE
Interconnect Switch is displayed.
NOTE: After user accounts are created, subsequent users will type their user name and password, then press the Enter key to gain access to the switch console.
The main menu displays the major categories for switch management.

Moving Between the Console Management Interfaces

The menu-driven interface is the factory default setting. To access the command line interface (CLI) from the menu-driven interface, highlight the Switch to CLI Mode option on the main menu and then press the Enter key. The command line prompt for the CLI will display.
HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide 1-3
Overview
When you are in a CLI session, you can access the menu-driven interface by executing the following command at the command prompt:
Command Description
menu
Moving between the CLI and menu-driven interface does not change the default interface. This means that if the default is the menu-driven interface and user 1 connects and switches to the CLI, when user 2 connects, they see the menu-driven interface when they log on.

Setting the Default Interface

Use the following command to change the interface default. This command takes effect immediately for the next log in. It will be lost, however, on reboot. To save the default permanently to non-volatile RAM (NVRAM), type the cfg save command. Refer to the “Saving Changes” section later in this chapter.
Use the following command to set the default interface:
Command Description
def-interface set {menu | cli}

Displaying the Default Interface

Use the following command to display the default interface:
Command Description
Toggles from the CLI to the menu-driven interface
Sets the default interface to either the menu-driven interface or the CLI
def-interface show
Displays the default interface

Using the CLI

This section describes how to use the command line interface to enter CLI commands.

Understanding Command Syntax Symbols

Command syntax is presented as a combination of defined strings, keywords, variables, and symbols. Symbols indicate how to enter the command, and should not be typed as part of the command itself.
Text in boldface must be entered literally as shown. Do not type any symbols that may appear in boldface.

Overview

This chapter describes how to configure the GbE Interconnect Switch from the command line interface (CLI).

Saving Changes

The GbE Interconnect Switch has two types of memory: dynamic RAM and non-volatile RAM (NVRAM).
Restarting the GbE Interconnect Switch erases all configuration settings in RAM and reloads the stored settings from NVRAM. Thus, it is necessary to save all configuration setting changes to NVRAM before rebooting the GbE Interconnect Switch.
2
Command Line Interface
After the configuration settings have been saved to NVRAM, they become the current runtime settings for the GbE Interconnect Switch. These settings are then used every time the GbE Interconnect Switch is rebooted.
Use the following command to retain any configuration changes permanently in NVRAM:
Command Description
cfg save
IMPORTANT: After saving your final configuration, HP highly recommends that you save the
configuration image to TFTP server storage. Refer to the “Initiating a TFTP Upload for Log File or Configuration File” section later in this chapter for more information.
Use the following command to display the current configuration settings:
Command Description

Configuring the GbE Interconnect Switch using the Command Line Interface

Configuring Remote Management IP Interface Settings

Each GbE Interconnect Switch must be assigned its own IP address, which is used for communication with an SNMP network manager or other TCP/IP application (for example Web or TFTP). The factory default is set for the GbE Interconnect Switch to automatically obtain the IP address using DHCP service from a DHCP server on the attached network. You can manually change the default switch IP address to meet the specification of your networking address scheme. If you select the manual mode and do not assign the IP address, the system assigns a default IP address for Switch A as 10.90.90.90 and for Switch B as
10.90.90.91. The system also assigns a default subnet mask of 255.0.0.0.
The GbE Interconnect Switch IP address is also assigned a unique MAC address by the factory. This MAC address cannot be changed and can be found on the initial boot console screen and the Logon screen, or by accessing basic switch information. Refer to the “Displaying Basic GbE Interconnect Switch Information” section later in this chapter.
In addition, you can
•
Set an IP address for a default gateway. This becomes necessary when the network management station is located on a different IP network from the GbE Interconnect Switch, making it necessary for management packets to go through a router to reach the network manager, and vice-versa.
•
Set a list of up to eight secure IP addresses of network management stations that are allowed to manage the interconnect switch. Only those network management stations can access the switch management inerfaces once set.
•
Set a management VLAN ID (VID) for the IP interface so that the GbE Interconnect Switch can be accessed from the designated management VLAN.
•
Change the default SNMP community strings in the GbE Interconnect Switch and set the access rights of these community strings. Refer to the “Adding SNMP Management Interface Community Strings” section later in this chapter.

Setting the Remote Management IP Interface Settings

To access and manage the GbE Interconnect Switch from an SNMP-based Network Management System, or by using the Telnet protocol or the Web, you must first configure the remote management IP interface parameters.
The IP address can be assigned by one of the following methods:
•
Manual—This option allows you to manually configure an IP address, subnet mask, and default gateway for the GbE Interconnect Switch.
•
BOOTP—This option configures the switch to send out a BOOTP broadcast request for IP information. The BOOTP protocol allows IP addresses, network masks, and default gateways to be assigned by a central BOOTP server attached to the same network to which the GbE Interconnect Switch is connected.
•
DHCP—This option configures the switch to send out a DHCP broadcast request. The DHCP protocol allows IP addresses, network masks, and default gateways to be assigned by a DHCP server attached to the same network to which the GbE Interconnect Switch is connected. DHCP protocol is the factory default mode.

Configuring MAC Address Aging Timer

The GbE Interconnect Switch enters into its forwarding table the mapping between the MAC address of the device and the Ethernet port to which the device is attached. This information is used to forward packets. This reduces the traffic congestion on the network, because packets are forwarded to the destination port only, instead of being forwarded to all ports.
The MAC address aging timer prunes the forwarding table addresses entries that are no longer used. Dynamic forwarding table entries, which are made up of MAC addresses and their associated port numbers, are deleted from the table if they are not seen within the aging timeout. The aging time can be from 10 to 1,000,000 seconds with a default value of 300 seconds. A very long aging time can result in dynamic forwarding table entries that are out­of-date or no longer are used.
If the aging time is too short, however, many entries may be aged out too soon. This will result in a high percentage of received packets whose destination addresses cannot be found in the forwarding table. In this case the GbE Interconnect Switch will broadcast the packet to all ports, negating many of the benefits of having a switch.
Static forwarding entries are not affected by the aging time.
The following shows the factory default setting for the MAC address aging time:
Feature Default Value
MAC Address Aging Time 300 seconds

Configuring IGMP Snooping

Internet Group Management Protocol (IGMP) snooping, when enabled and configured properly, manages multicast traffic through a GbE Interconnect Switch. IP multicast traffic is forwarded based on multicast group membership information registered by the GbE Interconnect Switch. The GbE Interconnect Switch can use IGMP snooping to configure ports dynamically, so that IP multicast traffic is forwarded only to those ports associated with IP multicast hosts, based on membership information.
IGMP snooping allows the GbE Interconnect Switch to recognize IGMP queries and reports sent between network stations or devices and an IGMP host that belongs to a specific multicast group. When enabled for IGMP snooping, the GbE Interconnect Switch can open or close a port to a specific device based on IGMP messages passing through the module. This feature further limits unnecessary broadcasts. The GbE Interconnect Switch can be configured to make queries using either IGMP version 1 or version 2.
When IGMP snooping is enabled globally on the GbE Interconnect Switch, you can enable or disable individual VLANs for IGMP snooping.
When IGMP snooping is enabled, any port receiving IGMP response packets will forward them to the CPU, and the CPU sets this port as a member of the corresponding multicast address.
The GbE Interconnect Switch supports three multicast group address filtering modes for making forwarding decisions regarding multicast packets.
•
Forward all group addresses—All multicast packets destined for all group MAC addresses are forwarded according to the VLAN rules.
•
Forward all unregistered group addresses—All multicast packets with group MAC address registration entries existing in the multicast table (both static multicast and group multicast created by IGMP snooping) are forwarded to member ports. If the group MAC address does not exist in the multicast table, packets are forwarded according to the VLAN rules.
•
Filter all unregistered group addresses—All multicast packets with group MAC addresses are forwarded only if such forwarding is explicitly permitted by a group address entry in the multicast table. If the group MAC address exists in the multicast table, then the packets are forwarded using the port member list for that entry. If the group MAC address does not exist in the multicast table, the packets are dropped.

Configuring Class of Service, Default Port Priority, and Traffic Class

Class of Service (CoS) for packet prioritization allows you to set priority levels for forwarding packets based on the priority setting information in the packets.
The GbE Interconnect Switch supports four classes (0-3) of traffic (buffers or queues) per egress port. You can map eight priority levels (0-7) to the four queues. Traffic from a specific server port can be given priority over packets from other devices according to the range of priority levels. Seven (7) is the highest priority; zero (0) is the lowest priority. By default, queue 3 has the highest priority setting; queue 0 has the lowest priority setting.
You can set the following queue scheduling algorithms:
• • Strict Priority Based Scheduling (Strict): If there are any packets residing in the high
priority of the transaction, then they are taken up first for transmission.
Weighted Priority Based Scheduling (Round-robin): This option provides continuous transmitting packet count at each queue. If the count is used up, the next priority queue is taken up for the transmission. The range of packet count is from 1 to 255 per queue.
You can also enable or disable a latency-based limit on a per queue basis. If any packet latency is greater than the maximum latency, the packet is dropped.
The following shows the CoS factory default settings:
Feature Default Value
Scheduling Mechanism for CoS Queues Strict
CoS—Max Packets 10
CoS—Max Latency 0
Default Port Priority 0

Configuring Port Trunking

Port trunking allows several ports to be grouped together to act as a single link. This provides a bandwidth that is a multiple of a single link bandwidth. Port trunking is most commonly used to link a bandwidth-intensive network device or devices, such as a server, to the backbone of a network.
The GbE Interconnect Switch allows the creation of up to six port trunk groups, each group consisting of up to eight links (ports). HP recommends that the port trunk ports be members of the same VLAN. Only similar type ports can be members of port trunks. A combination of Fast Ethernet (FE) and Gigabit (GE) ports cannot be members of the same port trunk.
The configuration of the lowest numbered port in the group becomes the configuration for all of the ports in the trunk group. This port is called the master port of the trunk group, and all configuration options, including the VLAN configuration, which can be applied to the master port, are applied to the entire port trunking group.
Load balancing is automatically applied to the ports in the trunked group, based on the setting of the trunk load-sharing algorithm, and a link failure within the group causes the network traffic to be directed to the remaining links in the group.
Spanning Tree Protocol treats a port trunking group as a single link on the GbE Interconnect Switch level. STP uses the port parameters of the master port in the calculation of port cost and in determining the state of the port trunking group. If two redundant port trunking groups are configured on the GbE Interconnect Switch, STP blocks one entire group, similar to STP blocking a link in case of two redundant links.

Configuring the GbE Interconnect Switch using the Command Line Interface

Considerations when Creating a Port Trunking Group

When creating a port trunking group, consider the following rules that determine how the port trunk reacts in network topology:
•
The first port of the port trunk is implicitly configured to be the master logical port. This is the reference port used in configuration commands. It can be thought of as the logical port representing the entire group.
•
When using a port trunk, always reference the master logical port of the group when configuring or viewing VLANs.
•
VLANs configured to use other ports in the port trunk will have those ports deleted from the VLAN when the port trunk becomes enabled.
•
The Spanning Tree algorithm views port trunk ports as a single Spanning Tree port. The Spanning Tree port is represented by the master logical port.
•
If the VLAN settings of the master logical port are changed, the VLAN settings of all members of that port trunk are changed similarly.
•
If the IGMP snooping configuration for any port trunk member is changed, the IGMP snooping settings for all port trunk members are changed.
•
The port trunk takes precedence over any other setting. That is, the settings of trunked ports are the same as the master port settings.
•
When any trunked port becomes a non-trunked port, all of the port configurations are reset to default settings.
Refer to Appendix H in the HP ProLiant p-Class GbE Interconnect Switch User Guide for additional information on port trunking.
The following shows the factory default port trunking settings:

Configuring GVRP

GARP VLAN Registration Protocol (GVRP) is a Generic Attribute Registration Protocol (GARP) application that provides 802.1Q-compliant VLAN pruning and dynamic VLAN creation on 802.1Q tagged ports.
GVRP updates dynamic VLAN registration entries and communicates the new VLAN registration information across the network. This feature allows stations to physically move to other GbE Interconnect Switch ports and keep their original VLAN settings, without having to reconfigure the VLAN settings on the GbE Interconnect Switch.
With GVRP, the GbE Interconnect Switch can
•
Exchange VLAN configuration information with other GVRP switches.
•
Prune unnecessary broadcast and unknown unicast traffic.
•
Dynamically create and manage VLANs on switches connected through 802.1Q tagged ports.
HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide 2-33
Configuring the GbE Interconnect Switch using the Command Line Interface
The GbE Interconnect Switch provides oprions to enable or disable GVRP capability. If an
802.1Q tagged VLAN is enabled, but the GVRP is disabled, the only VLAN feature is static VLAN registration entries. HP recommends backing up static VLAN register entries to the configuration file.
If ingress filtering is enabled then the port will discard any frame received on that port whose VLAN classification does not include that port in its member set.
The following shows the GVRP factory default setting:
Feature Default Value
Switch GVRP Disabled

Configuring GbE Interconnect Switch Date and Time

The GbE 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 interconnect switch events in the history log.
When a new GbE Interconnect Switch is first booted up, the firmware clock starts at zero (0) and counts the seconds since bootup. In order for the clock to display the real date and time, you must either
•
Manually set the date and time on the interconnect switch, or
•
Enable Simple Network Time Protocol (SNTP) on the GbE Interconnect Switch, and then set the SNTP parameters.
SNTP allows the switch to synchronize its real time to the network time. When SNTP is enabled, the GbE Interconnect Switch sends a request to a primary SNTP server in each period of a specified polling interval asking for the Greenwich Mean Time (GMT). If the primary SNTP server is not available, the request is sent to a secondary SNTP server.
When SNTP is enabled, the following events cause the GbE Interconnect Switch to request the date and time through SNTP:
•
The polling interval time expires.
•
Changes are made to the configuration settings for Daylight Saving Time, time zone, SNTP Server 1 or Server 2, or polling interval.
•
SNTP state is changed from disabled to enabled.
2-38 HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide
Configuring the GbE Interconnect Switch using the Command Line Interface
The following shows the SNTP factory default settings:
Feature Default Value

SNTP Server 1 0.0.0.0
SNTP Server 2 0.0.0.0
SNTP Poll Interval
Time Zone -06.00
Daylight Saving Time (DST) Disabled
Offset in Minutes 60

Setting Date and Time Parameters Manually

IMPORTANT: If the system clock is set and power is lost to the interconnect switch, manual time
settings are reset to factory defaults when the interconnect switch is powered on. If this occurs, manually reset the date and time. If SNTP is configured, losing power has no effect, so no manual resetting of time is required.
If SNTP is configured, losing power has no effect.
The factory default for SNTP is set to disabled. This allows you to manually set the date and time on the GbE Interconnect Switch if desired. Use the time and date conventions in the following table when configuring the date, time, local time zone, and local daylight saving time parameters:
Table 2-2: Time and Date Conventions
Parameter Format

IMPORTANT: In the forced 100M/Full, 100M/Half, 10M/Full, and 10M/Half modes, auto MDI-X is disabled and a cross-over cable must be used.
IMPORTANT: If you have the ProLiant BL p-Class F-GbE Interconnect Kit option with the DualTSX Interconnect Modules, the management interface supports only 1000M/Full and Auto options for the speed/duplex settings for Gigabit uplink ports. The fiber Dual TSX Interconnect Module supports only 1000-Mb/s (Gigabit) speed, and not 10-Mb/s or 100-Mb/s.
Disables SNTP
SNTP must be set to disable in order to manually set the time and date.

Port Security Settings

The port security feature controls the address learning capability and the traffic forwarding decisions for a port or ports. When enabled, you specify a number of source addresses to be learned (locked) at the port. Any incoming packets that do not have the learned source addresses are discarded.
The maximum number of learned addresses is ten. When the maximum number is reached, any incoming packet without one of the learned addresses is discarded, and no more new addresses can be learned at this port.
There are two modes for learned addresses.
• • Reset—Tells the system to hold the learned addresses until the system is reset.
Timeout—Tells the system to delete the addresses when the aging timer expires.
The following shows the factory default port settings:
Feature Default Value
Port State Enabled

Flow Control Off
Port Security—Admin State Disabled
Port Security—Max Address 1

Configuring Bandwidth

The GbE Interconnect Switch allows you to set a bandwidth limitation that restricts the ingress (receiving) and egress (transmitting) packet rate for each port. If the packet rate exceeds the allowed bandwidth rate, the excess packets will be dropped.
Bandwidth is configured in 1 to 127 units. Each unit is 117,481 bytes per second (around 0.94 Mb/s) for ports 1-24 and 939,850 bytes (about 7.52 Mb/s) for optional ports.

Configuring Spanning Tree Protocol

IEEE 802.1D Spanning Tree Protocol (STP) allows for the blocking of links between switches to avoid loops within the network. When multiple links between the switches are detected, a primary link is established. Duplicated links are blocked from use and become standby links. The protocol allows for the duplicate links to be used in the event of a failure of the primary link. Once STP is configured and enabled, primary links are established and duplicated links are blocked and put into standby automatically. The reactivation of the blocked links (at the time of a primary link failure) is also accomplished automatically, without operator intervention.

HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide 2-51
Configuring the GbE Interconnect Switch using the Command Line Interface
STP communicates between switches on the network using Bridge Protocol Data Units (BPDUs). Each BPDU contains the following information:
•
The unique identifier of the switch that the transmitting switch currently believes is the root switch
•
The path cost to the root from the transmitting port
•
The port identifier of the transmitting port
The switch sends BPDUs to communicate and construct the spanning-tree topology. All switches connected to the LAN on which the packet is transmitted will receive the BPDU. BPDUs are not directly forwarded by the switch, but the receiving switch uses the information in the frame to calculate a BPDU, and if the topology changes, initiates a BPDU transmission.
The communication between switches via BPDUs results in the following:
•
One switch is elected as the root switch.
•
The shortest distance to the root switch is calculated for the switch.
•
A designated switch is selected. This is the switch closest to the root switch through which packets will be forwarded to the root.
•
A port for each switch is selected. This is the port providing the best path from the switch to the root switch.
•
Ports included in the STP are selected.
NOTE: Refer to Appendix E in the HP ProLiant BL p-Class GbE Interconnect Switch User Guide for more information on Spanning Tree Protocol.
The following shows the STP factory default setting:

2-52 HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide

Enabling STP

Spanning Tree Protocol (STP) can be enabled or disabled at the switch level. Only one spanning tree domain per GbE Interconnect Switch is supported. You can configure ports to participate in that spanning tree domain, by enabling or disabling the STP function on a per port basis. Ports can also be configured in STP bypass mode (fast forward mode) that allows the port to skip the initial STP states (listening and learning) before enabling it in the forwarding state.
IMPORTANT: The GbE Interconnect Switch supports mono-Spanning Tree Protocol. Multiple spanning tree domains are not supported. This means the Spanning Tree Algorithm makes calculations without considering the VLAN domains to which the ports belong. All ports that have STP enabled fall under one STP domain.
Use the following command to enable STP on the GbE Interconnect Switch, configure ports to participate in the spanning tree domain, or to enable bypass on a port.
Command Description
Configuring the GbE Interconnect Switch using the Command Line Interface
stp enable
{
feature |
bypass <portlist> |
port <portlist>
}
Enables STP on the GbE Interconnect Switch, enables bypass on a port or ports, or enables a port or ports to participate in a single spanning tree domain. Type one of the following in the command:
• feature—Type feature to enable STP
globally for the GbE Interconnect Switch.
• bypass <portlist>—Type bypass and the
port number or numbers to enable bypass on the specified ports.
• port <portlist>—Type port and the port
number or numbers to enable the port to participate in the spanning tree domain.
HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide 2-53

Disabling STP

Use the following command to disable STP on the GbE Interconnect Switch, disable ports from participating in the spanning tree domain, or to disable bypass on a port:
Command Description
stp disable
{
feature |
bypass <portlist> |
port <portlist>
}

Setting Global and Per Port STP Parameters

The following STP settings can be configured globally on the GbE Interconnect Switch:
• Bridging—Sets the following bridging options:
— Forward delay—Forward delay is the time any port on the GbE Interconnect Switch
spends in the listening state while moving from the blocking state to the forwarding state. Forward delay values range from 4 to 30 seconds.
Disables STP on the GbE Interconnect Switch, disables a port or ports from participating in a single spanning tree domain, or disables bypass on a port or ports
Type one of the following in the command:
• feature—Type feature to disable STP
globally for the GbE Interconnect Switch.
• bypass <portlist>—Type bypass and the
port number or numbers to disable bypass on the specified ports.
• port <portlist>—Type port and the port
number or numbers to disable the port from participating in the spanning tree domain.
— Hello time—Hello time is the interval between two transmissions of Bridge Protocol
Data Units (BPDU) packets sent by the root bridge to tell all other switches that it is the root bridge. If you set a hello time for the GbE Interconnect Switch, and it is not the root bridge, the set hello time will be used if and when your GbE Interconnect Switch becomes the root bridge. The hello time cannot be longer than the maximum age, otherwise, a configuration error will occur. Hello time values range from 1 to 10 seconds.
— Max age—At the expiration of the maximum age, if a Bridge Protocol Data Unit
(BPDU) has still not been received from the root bridge, the GbE Interconnect Switch will start sending its own BPDU to all other switches for permission to become the root bridge. If the GbE Interconnect Switch has the lowest bridge identifier, it will become the root bridge. Maximum values range from 6 to 40 seconds.
— Priority—The priority number is used in the voting process between switches on the
network to determine which switch will be the root switch. A low number indicates a high priority, and a higher probability that this GbE Interconnect Switch will be elected as the root switch. Priority values range from 0 to 65,535. Zero (0) indicates the highest priority.
2-54 HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide
Configuring the GbE Interconnect Switch using the Command Line Interface
• Port—Sets the STP priority and port cost parameters for one port or a series of ports
— Priority—This parameter sets the relative priority for the port. A lower number
indicates a higher priority and a greater chance of the port being elected as the root port.
— Port cost—Port cost is a value used by STP to evaluate paths. STP calculates port
costs and selects the path with the minimum cost as the active path.
IMPORTANT: Observe the following formulas when setting the STP parameters on the root switch:
• Max Age ≤ 2 x (Forward Delay - 1 second)
• Max Age ≥ 2 x (Hello Time + 1 second)
The following shows the factory default STP settings:
Feature Default Value
Bridge Max Age 20 seconds
Bridge Hello Time 2 seconds
Bridge Forward Delay 15 seconds
Bridge Priority 32768
Port Priority 128
Port Cost 19 for ports 1-20 and 23-24
4 for ports 21-22
IMPORTANT: The factory default settings should be adequate for the majority of installations. HP recommends that you keep the default settings as set at the factory unless it is absolutely necessary to change them.

Configuring Static (Destination Address) Filtering Table

The GbE Interconnect Switch uses a filtering database to segment the network and control communications between segments. It can also filter packets off the network for intrusion control. Static filtering entries can be made by MAC address.
Each port on the GbE Interconnect Switch is a unique collision domain and the interconnect switch filters (discards) packets whose destination lies on the same port as it originated. This keeps local packets from disrupting communications on other parts of the network.
For intrusion control, whenever the GbE Interconnect Switch encounters a packet originating from or destined to a MAC address entered into the filter table, the interconnect switch will discard the packet.
Some filtering is performed automatically by the GbE Interconnect Switch, including:
•
Dynamic filtering, which is automatic learning and aging of MAC addresses and their location on the network. Filtering occurs keeps local traffic confined to its segment.
•
Filtering performed by Spanning Tree Protocol to filter packets based on topology, making sure that signal loops do not occur.
•
Filtering performed for VLAN integrity. Packets from a member of a VLAN destined for a device on another VLAN will be filtered.
Some filtering requires the manual entry of information into a filtering table. This includes MAC address filtering, which is the manual entry of specific MAC addresses to be filtered from the network. Packets sent from one manually entered MAC address can be filtered from the network. The entry may be specified as source, destination, or both.
The following shows the static unicast and multicast filtering factory default settings:

Configuring VLANs

A Virtual Local Area Network (VLAN) is a network topology configured according to a logical scheme rather than the physical layout. VLANs can be used to combine any collection of physical LAN segments into an autonomous user group that appears as a single LAN. VLANs also logically segment the network into different broadcast domains so that logical packets are forwarded only between ports within that VLAN. Typically, a VLAN corresponds to a particular subnet, although not necessarily. VLANs can enhance performance by conserving bandwidth, and improve security by limiting traffic to specific domains.
The GbE Interconnect Switch supports only port-based IEEE 802.1Q tag-capable VLANs.
VLAN membership for each port can be set as follows:
• • Egress Port—This is a port on the interconnect switch that belongs to at least one
VLAN. By default all ports are egress members of DEFAULT_VLAN.
— Untagged Member—Ports that are untagged members of a VLAN participate in the
VLAN, but no tag is associated to the packet when leaving that port. Untagged member ports can only be a member of one VLAN at a time.
— Tagged Member—Ports with tagging enabled will insert the IEEE 802.1Q tag with
the VID number into all packets that flow out of it. Tagged member ports can be members of multiple VLANs at a time, as packets are tagged with the VLAN ID from which they originated. Tagged member ports link IEEE 802.1Q trunks that work as inter-switch connections to forward packets belonging to multiple VLANs, to which those tagged member ports belong. If a packet has been tagged, the port does not alter the packet, thus keeping the VLAN information intact. The VLAN information in the tag can then be used by other 802.1Q compliant devices on the network to make packet-forwarding decisions.
Forbidden Non-member—These ports are not a member of the VLAN and are also forbidden from joining a VLAN dynamically when GVRP is enabled.
If ingress filtering is enabled for a port, the interconnect switch examines the VLAN information in the packet header (if present) and decides whether or not to forward the packet. The VID should match the PVID of that port, otherwise, that incoming packet is discarded.
Packets cannot cross VLANs. If a member of one VLAN wants to connect to another VLAN, it must do so through a router.
2-64 HP ProLiant BL p-Class GbE Interconnect Switch Command Line Interface Reference Guide

Default VLAN

The GbE Interconnect Switch reserves one VLAN, VID 1, also called DEFAULT_VLAN. The factory default setting assigns all ports on the GbE Interconnect Switch to the default VLAN. As new VLANs are configured, their respective member ports are removed from the default VLAN.
Characteristics of DEFAULT_VLAN include:
•
•
•
•
•
•
Configuring the GbE Interconnect Switch using the Command Line Interface
DEFAULT_VLAN is an IEEE 802.1Q Static VLAN with VID equal to 1.
DEFAULT_VLAN cannot be deleted.
The VID cannot be changed. The VID that is equal to 1 is reserved for DEFAULT_VLAN.
The VLAN name can be changed to any other valid VLAN name.
You cannot delete a port from DEFAULT_VLAN, unless it is a member of another
802.1Q VLAN.
You cannot forbid a port from DEFAULT_VLAN, unless it is a member of another
802.1Q VLAN.
•
If a port is deleted from the only 802.1Q VLAN of which it is a member, then it will automatically become a member of DEFAULT_VLAN as an untagged, egress port.
•
If a port is assigned to a user-created 802.1Q VLAN, and is not a tagged egress port member of DEFAULT_VLAN (in other words, it is an untagged egress port), then it will be deleted automatically from DEFAULT_VLAN.

Setting the PVID for a Port

Port VLAN ID (PVID) is a classification mechanism that associates a port with a specific VLAN and is used to make forwarding decisions for untagged packets received by the port. For example, if Port 2 is assigned a PVID of 3, then all untagged packets received on Port 2 will be assigned to VLAN 3. This number is generally the same as the VID number assigned to the port.
Characteristics of a PVID include:
•
By default, the PVID of all ports is the same as the VID of DEFAULT_VLAN, which is equal to 1.
•
When a user creates an untagged 802.1Q VLAN and assigns a port, the PVID will be changed to the VID of that 802.1Q VLAN.
•
For a tagged port, the PVID will be the same as the VID of the IEEE 802.1Q VLAN to which this port was first assigned.
•
If the first IEEE 802.1Q VLAN to which the tagged port is assigned is deleted, the PVID will change to that of the second IEEE 802.1Q VLAN to which the port was assigned.
•
The PVID of a port can only be set to a VID of a VLAN for which the port is already a member.
Use the following command to set the PVID for a port or set of ports:
Command Description
vlan set pvid
port <portlist>
id <vlan_id>
Sets the PVID for the specified ports

Enabling Ingress Filtering on a Per Port Basis

If ingress filtering is enabled for a port, the interconnect switch will examine the VLAN information in the packet header (if present) and decide whether or not to forward the packet. The VID should match the PVID of that port, otherwise, that incoming packet is discarded.
If the packet is tagged with VLAN information, the ingress port will first determine if the ingress port itself is a member of the tagged VLAN.
•
If the ingress port is not a member of the tagged VLAN, the packet is dropped.
•
If the ingress port is a member of the 802.1Q VLAN, the interconnect switch then determines if the destination port is a member of the 802.1Q VLAN, the packet is forwarded and the destination port transmits it to its attached network segment.
If the packet is not tagged with VLAN information, the ingress port tags the packet with its own PVID as a VID (if the port is a tagging port). The interconnect switch then determines if the destination port is a member of the same VLAN (has the same VID) as the ingress port.
•
If the destination port is not a member of the same VLAN, the packet is dropped.
•
If the destination port is a member of the same VLAN, the packet is forwarded and the destination port transmits it on its attached network segment.
Ingress filtering is used to conserve bandwidth within the interconnect switch by dropping packets that are not on the same VLAN as the ingress port at the point of reception. This eliminates the subsequent processing of packets that will just be dropped by the destination port.
The following shows the factory default setting for ingress filtering:
Feature Default Value
Ingress-filtering Off
Use the following command to enable ingress filtering on a per port basis:
Command Description
ingress-filter enable port <portlist>

Configuring Port Mirroring

The GbE Interconnect Switch allows you to copy frames transmitted and received on a port (source) and redirect the copies to another port (target). You can attach a monitoring device to the mirrored (target) port, such as a sniffer or an RMON probe, to view details about the packets passing through the source port. This setting is useful for network monitoring and troubleshooting purposes.
Displays ingress filtering information for all ports
To display ingress information for a specified port or ports, type port and the port number or numbers.
The following configuration rules apply to any port mirroring configuration:
•
A target mirror port cannot be configured as a trunk member.
•
VLAN configuration settings for any ports configured for mirroring cannot be changed.
•
The source and target ports should be members of the same VAN.
The direction of traffic on the source port can be one of the following:
•
Ingress traffic (received packets) on the source port
•
Egress traffic (transmitted packets) on the source port
•
Ingress and egress traffic on the source port
IMPORTANT: You cannot mirror a fast port onto a slower port. For example, if you try to mirror the traffic from a 1000-Mb/s port onto a 100-Mb/s port, you can cause throughput problems. The port from which you are copying frames must support an equal or lower speed than the port to which you are sending the copies.

Configuring Thresholds for Broadcast, Multicast, DA-Unknown Storm Prevention or Monitoring

The GbE Interconnect Switch allows you to set a threshold (in packets per second) for three types of storms: broadcast, multicast, and one where the packet destination address (DA) is unknown. The higher the threshold, the more packets the GbE Interconnect Switch can accept per second. If the threshold is exceeded, any additional packets received are dropped. Entering a low value means packets have a greater chance to exceed the threshold and be dropped from the GbE Interconnect Switch.
The following shows the broadcast, multicast, and DA-unknown storm monitoring factory default settings:
Feature Default Value
Broadcast Storm Monitoring Disabled
Multicast Storm Monitoring Disabled
Destination Address Unknown Storm Monitoring Disabled

Configuring GbE Interconnect Switch Serial Port

A local console running a terminal emulation program can be connected directly to the GbE Interconnect Switch via the RS-232 serial (console) port on the front of the interconnect switch. A console connection is referred to as an out-of-band connection, meaning that the console is connected to the GbE Interconnect Switch using a different connection than that used for normal network communications. This enables you to use the console to set up and manage the GbE Interconnect Switch even if the network is down.
The serial port can be configured for either a console or a Serial Line Internet Protocol (SLIP) connection.
The following shows the serial port factory default settings:
Feature Default Value
Baud Rate 9600
Data Bits 8
Parity Bits None
Stop Bits 1
Local IP Address 0.0.0.0
