Hi all,

I have one catalyst 6509 running IOS and a 6513 running CatOS. I want to install a FWSM module on each switch with an active/standby failover configuration on the FWSM modules.

Does anybody knows if there is a problem with this type of configuratons when a switch runs CatOS and the ther one is running Cisco IOS?

The two units in a failover configuration should have the same major (first number), minor (second number), and maintenance (third number) software version. However, you do not need to maintain version parity on the units during the upgrade process; you can have different maintenance versions on the software running on each unit and still maintain failover support.
