To remove the specified aggregate policer from a policy map, use the no police aggregate
aggregate-policer-name policy-map class configuration command. To delete an aggregate policer and its
parameters, use the no mls qos aggregate-policer aggregate-policer-name global configuration
command.
This example shows how to create an aggregate policer and attach it to multiple classes within a policy
map. In the configuration, the IP ACLs permit traffic from network 10.1.0.0 and from host 11.3.1.1. For
traffic coming from network 10.1.0.0, the DSCP in the inbound packets is trusted. For traffic coming
from host 11.3.1.1, the DSCP in the packet is changed to 56. The traffic rate from the 10.1.0.0 network
and from host 11.3.1.1 is policed. If the traffic exceeds an average rate of 48000 bps and a normal burst
size of 8000 bytes, its DSCP is marked down (based on the policed-DSCP map) and sent. The ingress
policy-map is attached to a port.

Purpose
Specify the name of the class whose traffic policy you want to create
or change, and enter policy-map class configuration mode.
By default, no traffic classes are defined.
Apply an aggregate policer to multiple classes in the same policy
map.
For aggregate-policer-name, enter the name specified in Step 2.
Return to global configuration mode.
Specify the port to attach to the policy map, and enter interface
configuration mode.
Valid interfaces include physical ports.
Specify the ingress policy-map name, and apply it to a port.
Only one policy map per port is supported.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
