the setup as following, I have 3 FWSM installed on 3 different 6513 switches, two of them are on active/standby failover mode and the last one installed on disaster recovery area as a backup stand alone FW.
My concern is to have the 3 FWSMs in failover which not supported till now as per Cisco release notes so I'm thinking whether the changes modified on the active/standby FWSMs could be replicated to the third FW via the CSM either manually or automatically (script or whatever) to keep it synchronized with the failover pair?s configuration.
Briefly speaking, I need the third FWSM to be on standby in case if any failure occurred on the head office zone.
