I have a service policy on a 6509 interface so I can see what the packets per second of a video stream coming out of a DVR (digital video recorder) is. This DVR has 16 security cameras attached and I'm concerned that when someone views all 16 cameras the video stream is going to be huge.
So I create a service policy to match an access list for all IP from the DVR. But no counters increment unless I add in some other match statement. I added in a match protocol telnet and the service policy counters started to work. I removed the match on telnet and the counters stopped. Telnet has nothing to do with the DVR. Here is the config of the class map, policy map and show commands: (By the way video is streaming through this interface continually during this excercise)
MATCHING ACCESS LIST ONLY:
class-map match-any DVR
match access-group 130

policy-map DVR-test
class DVR
ROC-6509-DU-A#sh access-list 130
Extended IP access list 130

match access-group 130
match protocol telnet

Match: access-group 130
523896 packets, 70689220 bytes
30 second rate 3991000 bps
Match: protocol telnet

Class-map: class-default (match-any)

Match: any
If I remove the 'match protocol telnet' and clear the counters, no longer do the counters for the access-list 130 increment - put back in match telnet and they start to increment.
This is a Sup720 with IOS 12.2(18)SXE3
Is this a bug or do I not have my class map or policy map correct?
