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.

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.
