QOS question

Hi we make use of class-based QOS on our access switches interfaces.

When I do the following command I get a puzzling reply, in the below output you can see that NO traffic is being registered by the access-lists and class-maps, is this normal behaviour?

command: show policy-map interface fa0/1

FastEthernet0/1

Service-policy input: ax-qos

Class-map: voip-traffic (match-all)

0 packets, 0 bytes

offered rate 0 bps, drop rate 0 bps

Match: access-group name ax-qos_voip-traffic

Class-map: voip-signaling (match-all)

0 packets, 0 bytes

offered rate 0 bps, drop rate 0 bps

Match: access-group name ax-qos_voip-signaling

Class-map: voip-any (match-all)

0 packets, 0 bytes

offered rate 0 bps, drop rate 0 bps

Match: access-group name ax-qos_voip-any

Class-map: citrix (match-any)

0 packets, 0 bytes

offered rate 0 bps, drop rate 0 bps

Match: access-group name ax-qos_citrix

0 packets, 0 bytes

rate 0 bps

Class-map: managment (match-any)

0 packets, 0 bytes

offered rate 0 bps, drop rate 0 bps

Match: access-group name ax-qos_mgmt

0 packets, 0 bytes

rate 0 bps

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

0 packets, 0 bytes

offered rate 0 bps, drop rate 0 bps

Match: any

0 packets, 0 bytes

rate 0 bps

Re: QOS question

It looks like you have access-lists for your matching, but I see no access-lists shown for traffic to match to.

Yes ofcourse you right here is the access-lists configured

Re: QOS question

Is this a router or a switch? Can you send the 'show run' and 'show ver'?

Re: QOS question

This is a switch 3560 with IOS ver 12.2(35)SE1

Re: QOS question

That's what I thought. You can't use the 'show policy-map interface' commands on a Catalyst switch to get counters. Do a search on these forums for policy-map or qos counters on a Catalyst switch. Hint 'show platform'...
