Hi,
In order to see QoS marking stats you need to use the command "show
mls qos interface fastEthernet 0/x statistics " on _physical_
interfaces. However, this command displays the aggregate stats for the
port (incoming/outgoing) and might be confusing sometimes when you
have multiple traffic flows. The "classic" MQC show commands (e.g.
show policy-map interface) are not relevant when it comes to "MLS QoS"
:) For more examples of traffic policing in 3550/3560 (including
per-port/per-VLAN policing) you may check the following post:
Also, a working alternative to monitoring the traffic marking with
show commands in the switch is configuring an ingress policy-map in
the attached router (making sure the marked traffic goes to that
router). Assign class-map matching the respective DSCP values to the
policy-map, and you can see the packet statistics. I use this methond
extensively for verifications in our VOL1 QoS section.
HTH,
