You need:

int Gi1/1
   mls qos vlan-based
   switchport ... vlan 123
int Vlan123
   service-policy BLAH in

You should read up on PFC QoS, and in particular be aware that policers 
are not synced between forwarding engines, so if you are using DFCs, the 
rate will be the aggregate of each DFC ingressing the traffic.
