82 Cisco Systems Intelligent Gigabit Ethernet Switch Module
Figure 6-2 Management Module External Network Interface window
The BladeCenter Management Module defaults to the IP address 192.168.70.125. If you
have more than one BladeCenter on your Management Network, you are required to change
the external network interface (eth0). If you do not, you will have IP address conflicts that will
result in not being able to access your Management Modules. In Figure 6-2, we configured
the external interface to be on the same default management subnet with a unique IP
address.
After the external interface is configured, the internal interface needs to be configured with
another unique IP address. The purpose of internal network interface (eth1) (Figure 6-3) is to
communicate with the BladeCenter devices across an Ethernet link. Note that if you do not
configure the internal interface on the same network as the External interface, you will not
have IP connectivity from the Management Module to your switches modules.
