Using ACL's with Priority Queuing?

rlh
Level 1
Level 1

Is it possible to use access-lists with priority queuing? I need to prioritize some traffic over others by IP addresses (really, subnets) all of which come into the router via the same Ethernet interface. Nothing fancy... just "if List1 has traffic, it takes priority over List2, which takes priority over List3", etc. PQ's four levels are more than adequate, I just need a way to assign them by IP address rather than by incoming interface.

Thanks!

Yes, you can use access lists to qualify ip traffic eg

priority-list 1 protocol ip high list 100

Euthe basis, 1 -99, or extended 100 - 199 can be specified.

Would ICMP traffic be considered part of "IP" in access-list 100 as shown above? I want to treat TCP/IP and ICMP separately, relegating ICMP to low priority and TCP/IP to something higher. I know the ACL can separately specify "ip" and "icmp" (and "tcp" for that matter), but how inclusive is that "ip" in the priority-list command?
