WAAS: Standard vs Extended ACL's for WCCP Transparent Redirection

I've come across a number of implementations where the ACL's associated with services 61 & 62 are using extended access-list. I am writing with specific reference to wccp configured in promiscuous mode.


Since WCCP will only redirect TCP, and the WAAS solution in general applies only to TCP - then is there really a need for extended acls for redirection?. Furthermore, in a simple implementation you do not need separate acls linked to 61 & 62 - i don't think so.


Standard acls parse the filteration process more quickly than extended.

The extended access-lists are used because some TCP traffic does not to be optimized (telnet, BGP, SNMP, ...), or some hosts have compressed traffic for any application and need to be excluded from redirection. Besides that standard access-lists can be used.
