I'm in the process of implementing QoS on our network...I've already been using it on our Edge routers and that's working pretty well. However I'm having some issues doing it on the LAN, specifically on our 3750's.
To start I'm just trying to mark management traffic (ssh and telnet ports) with CS2 coming from my machine. The problem is that sho policy map int gi 3/0/43 doesn't increment the policy-map counters which I understand is a problem with all catalyst switches. However our 6500 I'm not seeing CS2 in netflow, and when I try to deny all traffic with CS2 just to test on the uplink on the 3750 it's blocking the traffic and the ACL counters for that line are not incrementing (deny ip any any dscp cs2). The uplinks on the 6500's have qos enabled and have mls qos trust on t he uplinks to the 3750, which is a Layer 3 Etherchannel port. Any ideas why this wouldn't work? Here is the config:
Use 'sh mls qos interface [interface] statistics' on the 3750's uplinks to the 6500's, physical ports not the etherchannel. If DSCP is getting changed as per your policy map then you will see the outgoing counters rising for CS2.
If they are rising then the 3750 is doing what it's told.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
