Step 12 copy running-config startup-config
To remove the specified aggregate policer from a policy map, use the no police aggregate
aggregate-policer-name policy map configuration mode. 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 incoming 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 b/s and a normal burst
size of 8000 bytes, its DSCP is marked down (based on the policed-DSCP map) and sent. The policy
map is attached to an ingress port.
