Cisco Cisco Catalyst 6500 Series Firewall Services Module

Access list optimization might create an access list that is inaccurate compared to the original access 
list. This may cause packets to be denied when they should be permitted by the access list.

Workaround: Disable access list optimization with the no access-list optimization enable 
command.

The caveats listed in 

 were resolved in software Release 4.0(4), and were not previously 

documented. If you are a registered Cisco.com user, view more information about each caveat using the
