5.3 Multiple Nortel Networks L2/3 GbESMs in a BladeCenter
If there are two (or more) switches in a single IBM Eserver BladeCenter chassis, the management (MGTx) interfaces of all of the switches are on VLAN 4095. This has the following consequences:
All of the MGTx IP addresses that are configured through the Management Module Web interface should be on the same subnet as the Management Module internal and external port IP addresses (to allow for access through the Management Module). This configuration also makes it possible to Telnet from one switch module to another across the midplane of the chassis.
It is not possible to pass substantive data between switch modules across the midplane using the MGTx ports. The Nortel Networks L2/3 GbESM will not forward data between the MGTx ports and any of the internal (INTx) or external (EXTx) ports. If you want to pass data from one switch module to another, then the modules must be either cabled directly to each other or connected by way of an external switch or router.
