What to configure

You need to configure the switch module IP addresses and subnet mask through the management module Web interface to have switch module communication with the management module and remote management station (IBM Director server and console, for example). This is in addition to the IP addresses configured in the management module. You might also need to use the firmware in the switch module to configure the switch external ports to operate in the correct link aggregation (trunking) mode, or to configure any VLANs or other special conditions.

Note: To access the firmware in the switch module, make sure the following configuration items in the management module are set to Enabled:

vSwitch module external ports

vExternal management for the external ports

In the management module Web interface, under I/O Module Tasks, click Management → Advanced Management → Advanced Setup and enable the items.

Because all blade servers in the BladeCenter chassis share access to the external LAN through the switch ports, you can configure the ports on a switch module to operate together as an aggregate link, or trunk. An aggregate link provides more bandwidth than a single link to the attached LAN.

Notes:

1.The attaching LAN switch must have a compatible multi-port trunk configuration.

2.Configure link aggregation before you attach cables between the external ports and your LAN equipment.

You configure the switch through the firmware on the switch module, which you can access through the Web interface to the management module (click I/O Module Tasks → Management in the navigation panel).

Note: You can also access the firmware on the switch module directly through an external switch module port, using a Telnet interface or a Web browser and the switch IP address. See the documentation that comes with the switch module for more information.

You can configure the IP addresses, subnet mask, and protocols through the IBM BladeCenter Deployment Wizard, which is a function of the IBM Director product. You can also configure external switch module ports for multi-port link aggregation through the Wizard.

Important: For a remote management station, such as the IBM Director server, to communicate with the switch modules in the BladeCenter unit, the switch modules must be on the same subnet as the management module.

Supporting Ethernet failover

To have the BladeCenter unit support Ethernet failover on the blade servers, set up the BladeCenter unit and blade servers as follows:

vConfigure the Ethernet controllers in one or more blade servers for failover (see the blade server documentation and the operating-system documentation for information).
