Configuring the Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM BladeCenter

Note: For Cisco IOS release 12.1(22)EA6a and later, the SOL VLAN ID is set to a default value of 4095. If you use the default SOL VLAN ID of 4095, no additional configuration of the Cisco Systems Intelligent Gigabit Ethernet Switch Module is required. You need to complete the following procedure if you set a custom SOL VLAN ID.

Complete the following steps to configure the Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM® BladeCenter®. The Cisco Systems Intelligent Gigabit Ethernet Switch Module has built-in support for the SOL feature and does not require a firmware upgrade.

Note:

You will not be able to perform this procedure if the values for the network configuration of the Cisco Systems Intelligent Gigabit Ethernet Switch Module are not within the same subnet as the BladeCenter management-module network interfaces (eth0 and eth1). See Configuring the management module for information.
If you are using management channel auto discovery (MCAD), replace references to I/O-module bay 1 in the following procedure with the I/O module bay number that is actually being used (see the BladeCenter Advanced Management Module User's Guide for additional information about MCAD).

Start the BladeCenter management-module Web interface (see Starting the BladeCenter management-module Web interface).
In the navigation pane, click I/O Module Tasks → Configuration.
Scroll to the Current IP Configuration section and make sure that it contains values that are within the same subnet as the BladeCenter management-module network interfaces (eth0 and eth1). If the values are not in the same subnet, you must modify them before you continue. See Configuring the management module for information.
Scroll to the Bay 1 (Ethernet SM)* section; then, click Advanced Management.
Scroll to the Start Telnet/Web Session section; then, click Start Telnet Session. This will start a new Telnet session and connect to the Cisco Systems Intelligent Gigabit Ethernet Switch Module Telnet interface.
Log in to the Cisco Systems Intelligent Gigabit Ethernet Switch Module Telnet interface.
Complete the following steps to activate the VLAN ID for the Cisco Systems Intelligent Gigabit Ethernet Switch Module:
1. Type en and then press Enter.
2. Type config t and then press Enter.
3. Type vlan vlan_id, where vlan_id is the VLAN ID that was set for the management module (see Configuring the global SOL settings for the BladeCenter unit); then, press Enter.
4. Type state active and then press Enter.
5. Type end and then press Enter.
6. Type wri and then press Enter.
Attention: To maintain system security, you must remove the SOL VLAN ID from the external ports of the Cisco Systems Intelligent Gigabit Ethernet Switch Module.
Complete the following steps to remove the SOL VLAN ID from the external ports of the Cisco Systems Intelligent Gigabit Ethernet Switch Module:
1. Type config t and then press Enter.
2. Type int gi0/port_number , where port_number is an external port number from 17 through 20 for the switch module; then, press Enter.
3. Type switchport trunk allowed vlan remove vlan_id, where vlan_id is the VLAN ID that was set in step 7.c (4095, by default); then, press Enter.
4. Repeat step 8.b and 8.c for each external port number from 17 through 20.
5. Type end and then press Enter.
6. Type wri and then press Enter.
Note: For SOL operation with Cisco IOS releases earlier than 12.1(22)EA6a, the internal interfaces of the Cisco Ethernet Switch Module must be set to trunk mode. Trunk mode is the default configuration. If SOL sessions do not go into a Ready state and you are using Cisco IOS releases earlier than 12.1(22)EA6a, perform the procedure in step 9 to configure trunk mode.
Complete the following steps to configure the internal interfaces of the Cisco Systems Intelligent Gigabit Ethernet Switch Module for trunk mode:
1. Type config t and then press Enter.
2. Type int gi0/port_number , where port_number is an external port number from 1 through 14 for the switch module; then, press Enter.
3. Type switchport mode trunk and then, press Enter.
4. Repeat step 9.b and 9.c for each external port number from 1 through 14.
5. Type exit and then press Enter.
6. Type int gi0/port_number , where port_number is an external port number from 1 through 16 for the switch module; then, press Enter.
7. Type sw trunk allow vlan add vlan_id, where vlan_id is the VLAN ID that was set in step 7.c; then, press Enter.
8. Repeat step 9.f and 9.g for each external port number from 1 through 16.
9. Type end and then press Enter.
10. Type wri and then press Enter.
Type exit and then press Enter to close the Cisco Systems Intelligent Gigabit Ethernet Switch Module Telnet interface session.
Close the window in which the Telnet session was running.
