IOS Switch QOS

Hi,

Simple question that I can't seem to find an answr for, is there any show command on a switch that will show me the stats on the QOS markings of packets? and/or stats on the varous queues set up.

If I use Policy based QOS I can sue

#show service policy int x/x

and it shows me how many packets each class has seen and marked/queued.

but after setting up port based QOS,
platform qos trust cos wrr-queue bandwidth 20 100 200 
 priority-queue queue-limit 5 
 wrr-queue queue-limit 65 15 15 
 wrr-queue random-detect min-threshold 1 70 100 100 100 100 100 100 100 
 wrr-queue random-detect min-threshold 2 70 100 100 100 100 100 100 100 
 wrr-queue random-detect min-threshold 3 40 40 50 50 60 60 70 70 
 wrr-queue random-detect max-threshold 1 100 100 100 100 100 100 100 100 
 wrr-queue random-detect max-threshold 2 100 100 100 100 100 100 100 100 
 wrr-queue random-detect max-threshold 3 70 70 80 80 90 90 100 100 
 wrr-queue cos-map 2 1 1 2 
 wrr-queue cos-map 3 5 3 4 
 wrr-queue cos-map 3 7 6 7 
 rcv-queue cos-map 1 2 1 
 rcv-queue cos-map 1 3 2 
 rcv-queue cos-map 1 4 3 
 rcv-queue cos-map 1 5 4 
 rcv-queue cos-map 1 6 5 
 rcv-queue cos-map 1 7 6 
 rcv-queue cos-map 1 8 7 
 auto qos voip trust 

I can sue the command

#show queuing int x/x

but this only seems to show dropped packets. I would like a command to show me that traffic is getting correctly classified and assign to the right queue.

And what is the current recommendation, using PFC QOS with (#policy-map type lan-que) or port based QOS as configured above. I assume there is a CPU over head in using PFC based?

Cheers

    Try "sh mls qos int <x/x> stat"

    What model is it?
