3560 QOS - no hits in classes when doing sh policy-map interface

pattyj

Level 1

On my 3560 when I applied a inbound Marking policy-map on a port I do not see any hits in the classes.  What am I misssing?

interface GigabitEthernet0/3
description "NetApp -usplbx001-standby"
switchport access vlan 3
switchport mode access
no mdix auto
spanning-tree portfast

Your'e not missing anything, it is a well known limitation with the 3560 and 3750 switches. Because the packets are switched in hardware the 3560 switch does not keep acl or QOS policy map counters.

The best you can do on these switches is "sh mls qos interface statistics" which gives some general info on what is happening with QOS on the switch.
