Configuring CoPP for CPU Queues

This section describes how to create a queue-based CoPP service policy and apply it to control plane traffic.
Controlling traffic on the CPU queues of the control plane does not require ACL rules; only QoS rate-limiting
policies are used.
To create a queue-based CoPP service policy, you must create a QoS input policy with rate-limiting,
associate it with a control-plane queue in a QoS policy map, and apply the complete queue-based rate
limiting configuration to control-plane traffic.
1 Create a QoS input policy and configure a rate limit.
CONFIGURATION mode
qos-policy-input name cpu-qos
rate-police [rate-kbps] [burst-kbytes] peak [rate-kbps] [burst-kbytes]
2 Create an input policy-map to assign the QoS rate-limit policy to a control-plane queue.
CONFIGURATION mode
policy-map-input name cpu-qos
service-queue queue-number qos-policy name
On the switch, the range of queue-number values is from 0 to 20. The twenty-four control–plane
queues are 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.
