Policy Map Configuration

Command Usage

• Use the policy-map command to specify a policy map and enter Policy Map

configuration mode. Then use the class command to enter Policy Map Class
configuration mode. And finally, use the set and police commands to specify
the match criteria, where the:
- set command classifies the service that an IP packet will receive.
- police command defines the maximum throughput, burst rate, and the

action that results from a policy violation.

You can configure up to 16 rules per Class Map. You can also include multiple
classes in a Policy Map

.

Example
This example creates a policy called “rd_policy,” uses the class command to specify
the previously defined “rd_class,” uses the set command to classify the service that
incoming packets will receive, and then uses the police command to limit the
average bandwidth to 100,000 Kbps, the burst rate to 1522 bytes, and configure the
response to drop any violating packets.
