Solution

The second Ethernet interface can be configured as redundant or active, in the Meru controller.

CONFIGURATION STEPS:

Redundancy can be configured only through CLI.

CLI Steps :

Step 1 : Do not connect any Ethernet cable to the second Ethernet interface (G2) until we finish configuring the second interface(G2)

Step 2 : Log into the console session, telnet or SSH and run the following commands :

Meru# configure terminal
Meru(config)# bonding dual
Meru(config)# exit
Meru# copy running‐config startup‐config

Meru(config)# interface FastEthernet 2
Meru(config-if-FastEth)# type redundant
Meru(config-if-FastEth)# exit
Meru(config)# exit
Meru#copy running-config startup-config

Step 3 : Once after saving the configuration, we need to reboot the controller for the changes to take effect.

Step 4 : We need not specify an ip for secondary interface as it will receive the IP address of the primary interface when the failover occurs.

EXPECTED BEHAVIOUR : Once when the primary interface of the controller goes down, the secondary interface would take over the network with the same ip as that of primary interface.
