• Assign the QoS service policy to control plane queues. By default, the peak information rate (pir) and committed information rate (cir) values are in packets per second (pps) for control plane. CoPP for CPU queues converts the input rate from kilobits per second (kbps) to packets per second (pps), assuming 64 bytes is the average packet size, and applies that rate to the corresponding queue - One kbps is roughly equivalent to two pps. 1. Create a control-plane type class-map and configure a name for the class-map in CONFIGURATION mode. class-map type control-plane example-copp-class-map-name 2. Return to CONFIGURATION mode. exit 3. Create an input policy-map to assign the QoS policy to the desired service queues in CONFIGURATION mode. policy-map type control-plane example-copp-policy-map-name 4. Associate a policy-map with a class-map in POLICY-MAP mode. class example-copp-class-map-name 5. Configure marking for a specific queue number in POLICY-MAP-CLASS-MAP mode. Use the show control-plane info command to view the list of control-plane queues. set qos-group queue-number 6. Configure rate policing on incoming traffic in POLICY-MAP-CLASS-MAP mode. police {cir committed-rate | pir peak-rate} • cir committed-rate-Enter a committed rate value in pps, from 0 to 4000000. • pir peak rate - Enter a peak-rate value in pps, from 0 to 40000000.

To enable CoPP, apply the defined policymap to CONTROL-PLANE mode. 1. Enter CONTROL-PLANE mode from CONFIGURATION mode. control-plane 2.
