• Policing is based on a token bucket, where bucket depth (i.e., the
maximum burst before the bucket overflows) is by specified the
burst-byte field, and the average rate tokens are removed from the
bucket is by specified by the rate-bps option.
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.
service-policy
This command applies a policy map defined by the policy-map command
