Upgraded from FWSM 2.2 single routed context to FWSM 3.1.5, multiple context, transparent mode on 6513( Sup2 MSFC2 ver 12.2(18)SXF6), no ACLs on router. Number of Vlans and hosts didn't change. After the upgrade ping respons times to machines behind the router/ firewall are much higher and irregular. Anyone has a clue what could cause this difference and how to 'stabilize' ping times ? Overall performance seems good. I had no complaints from customers yet, but our Nagios management system keeps sending these messages about to high respons times. More info and details available on request.
