The show mls qos interface statistics verification command reports dynamic counters for a given
policy, including how many packets were classified and policed by the policy.
In the example below, untrusted packets from the PC are classified and policed according to the limits
shown in Figure 2-4 for the Untrusted PC + SoftPhone + Scavenger access edge endpoint policing
model.

The show policy interface verification command displays the policy maps (and related classes) that are
attached to a given interface.
In this example, a summary of the Untrusted PC + SoftPhone + Scavenger policing policy is shown as
applied to FastEthernet0/1.
