Cisco Cisco Catalyst 6500 Series Firewall Services Module

With SCCP V17, the FWSM becomes inaccessible when dual stack or IPv6 traffic passes through. 

Call flow:

Phone A (dual stack) --> FWSM --> CUCM (dual stack) --> FWSM -- Phone B

When Phone A calls Phone B via the FWSM and CUCM, the FWSM unexpectedly reloads. 

Workaround: Remove the dual stack or IPv6 configuration on the Phones and CUCM.

The FWSM unexpectedly reloads with a high RTSP traffic load when RTSP inspection is enabled. 
This occurs with a large amount of RTSP traffic, around 42K connections/sec including RTSP traffic 
through the box. This software reload is not seen with a single RTSP connection. 

Workaround: Disable RTSP inspection or reduce the amount of traffic.

When trying to distribute a large number of GLOBAL lines into OSPF on an FWSM, the OSPF 
process may stop processing new LSAs and no longer update the routing table of its peers.

Workaround: If possible, summarize the routes you are trying to distribute, thereby decreasing the 
load on the OSPF process.
