Hi,
Having problem with custom queue not matching packets, I configured the same access-list on 2 routers.
R1 uses CQ and R4 uses CBWFQ. R4 matches the packets, R1 does not. It seems to be an IOS problem
with CQ. Version is C2600-J1S3-M, 12.2(15)T5is.
Have you seen this behavior?
Traffic is destinated to BB1, using RTR. BB1 is reachable through R1 ethernet0/0.
R4
Rack2R4#sh access-list 109
Extended IP access list 109
10 permit udp any any range 1000 2000 (350 matches)
Rack2R1#sh access-list 109
Extended IP access list 109
10 permit udp any any range 1000 2000
CBQWF selects the traffic, CQ does not (on R1 udp should go to queue # 4):
Rack2R4#sh policy-map int ser 0/0
Serial0/0
Service-policy output: Compare-to-CQ
Class-map: udp-100-1500 (match-all)
217 packets, 13888 bytes
5 minute offered rate 1000 bps, drop rate 0 bps
Match: access-group 109
Queueing
Output Queue: Conversation 41

Rack2R1#sh queuei custom
Current custom queue configuration:
List Queue Args

12 5 protocol ip list 110
12 4 byte-count 512 limit 0
12 5 byte-count 5120
12 6 byte-count 45000
(I would not use CQ on the real world, but you know, on the lab...it is another history)
