Simulate interface counters with QoS policy-map

If you need interface counters on subinterfaces or virtual interfaces, you can emulate them with an empty policy-map, for example:

policy-map Count
class class-default
!
interface Serial0/0/0.100 point-to-point
service-policy input Count
service-policy output Count
The service policy counters are then inspected with the show policy-map interface name command:
a1#show policy-map interface Serial 0/0/0.100

Serial0/0/0.100

Service-policy input: Count

Class-map: class-default (match-any)
10 packets, 840 bytes
1 minute offered rate 0 bps, drop rate 0 bps
Match: any

Service-policy output: Count

Class-map: class-default (match-any)
61 packets, 7084 bytes
1 minute offered rate 0 bps, drop rate 0 bps
Match: any
