As another poster pointed out it doesn't look like you have the policy-map applied to the interface.

If the QoS WAS working, then you would see stats that reflect packets having the DSCP value changed on ingress. These show up in the "classified" column.

EG.

#show mls qos int fa0/3 stat
FastEthernet0/3
Ingress
  dscp: incoming   no_change  classified policed    dropped (in pkts)
    0 : 2060620    1127162    119850     0          0
    8 : 0          0          0          0          0
    16: 0          0          0          0          0
    24: 0          0          0          0          0
    32: 0          0          0          0          0
    40: 0          0          0          0          0
    46: 0          0          186796526  0          0
    56: 119850     0          0          0          0
Others: 185863068  0          0          0          0


In this example there has been 186796526 inbound packets that have been classified as DSCP-46 by the QoS policy. This is the number that you need to see incrementing if your QoS policy is working. If a packet enters that already is marked as DSCP-46 and it matches your QoS policy to tag it as DSCP-46 too, then it should go into the "no change" column.
