FWSM failover

Guys,

I have a dought about failover with FWSM.

I have 2 Cisco 6500 with FWSM board. They work with Active (Primary) /Standby (Standby).

This days, I had a problem with Active,  then, the Standby was changed to Active, ok.

When the Primary returned, I checked that the Secondary FWSM configuration had a line: "no failover"

I didn't understood  why the Secondary changed this line, because before of problem this line was "failover".

So, i had to change this line putting: failover and them normalize.

Someone knows why the Secondary FWSM changed the line failover to no failover?  Is normal? I could to configure it to don't change?

Thank you!

Anderson.

FWSM failover

Hi Anderson,

The most common cause of this is if you have a different set of VLANs passed to the FWSMs. Check the output of 'show run | i firewall' on both 6500s and make sure the output matches exactly on both sides.
