This example creates a policy called "rd-policy," uses the
specify the previously defined "rd-class," uses the set cos command to
classify the service that incoming packets will receive, and then uses the
police flow command to limit the average bandwidth to 100,000 Kbps, the
burst rate to 4000 bytes, and configure the response to drop any violating
packets.
