Queue-based Control Plane Policing
When configuring a queue-based CoPP policy, take into account that there are twenty-one CP queues
divided into groups of 7 queues for the Route Processor, Control Processor, and line-card CPUs:
• 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.

The protocols mapped to each CPU queue and the default rate limit applied to the 7 CPU queues for the
Route Processor, Control Processor, and line cards are as follows.
