10 Control Plane Policing (CoPP) Control plane policing (CoPP) uses access control list (ACL) rules and quality of service (QoS) policies to create filters for a system's control plane. The CoPP filters prevent traffic that is not identified as legitimate from reaching the control plane, and rate-limit traffic to an acceptable level. On the switch, the control plane has 21 queues (0 to 20) divided into groups of seven queues for the Route Processor, Control Processor, and line-card CPUs as follows: • Queues 0 to 6 process packets destined to the Control Processor CPU . • Queues 7 to 13 process packets destined to the Route Processor CPU. • Queues 14 to 20 process packets destined to the line card CPU. clear control-traffic protocol Clear all per-protocol counters of rate-limited control-plane traffic.

Enter the keyword all to clear counters for all protocol rate-limiting traffic information. Enter the keyword pe and the port extender ID. The PE ID range is from 0 to 255. Enter the keyword stack-unit and the stack unit number. The stack-unit range is from 0 to 7. Enter the keyword portset and the port-pipe ID. The portpipe ID value is 0.
