42 Nortel Networks L2/3 Ethernet Switch Module for IBM Eserver BladeCenter
other network management products. The MIBs that are provided include Nortel
proprietary extensions to the standard MIB1 and MIB2 objects. Both read and write
access to these variables can be configured.
5.3 Multiple Nortel Networks L2/3 GbESMs in a BladeCenterIf 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.
