Control Plane Policing (CoPP)
Control plane policing (CoPP) uses access control list (ACL) rules and quality of service (QoS) policies to create lters for a system’s
control plane. The CoPP lters prevent trac that is not identied as legitimate from reaching the control plane, and rate-limit trac
to an acceptable level.
On the Z9500 switch, the control plane has 24 queues (0 to 23) divided into groups of eight queues for the Route Processor,
Control Processor, and line-card CPUs as follows:
• Queues 0 to 7 process packets destined to the Control Processor CPU .
• Queues 8 to 15 process packets destined to the Route Processor CPU.
• Queues 16 to 23 process packets destined to the line card CPU.

To manage control-plane trac, enter control-plane mode and congure the switch.
