I have VLAN based policy as per below.
sh mls qos inte XX stati shows correct marking, however show policy map vlan does not show any traffic clocking up.
I have applied similar strategy on 7600 and can see traffic rate on policy map.
access-list 101 permit ip any any
class-map match-all MNGT
match access-group 108
set dscp cs3
service-policy input MVB-MNGT
mls qos vlan-based
no cdp enable
This is a limitation with the hardware on the 3560/3750 platforms. At this time we wont show # of policy-map matches in 'show policy-map interface'.
I dont believe there is a plan to fix this, so the best idea is using the 'show mls qos interface statistics' to make sure the policy is working.
