WiSM redundancy/failover

Answered Question
Sep 12th, 2008

Cisco documents mentions only up to tertiary WLC. The thing is each WiSM has 2 WLC 4404 cards. We have 2 WiSM modules. How do we configure the WiSM modules for redundancy/failover? -Thanks

I have this problem too.

Yes... same mobility group... so in case you have roaming between the A and B wlc's you will be okay.

If you have two WiSM's in one chassis then I would set it up like this... no need for a tertiary:

WiSM 1 WLC 1 A

WiSM 1 WLC 2 B

WiSM 2 WLC 1 A

WiSM 2 WLC 2 B

Just break up the sections via floor, building or sections.

ex.

A = floors 1-3

B = floors 4-6
