Examples of Configuring CoPP for CPU Queues

Example of Creating a QoS Policy to Configure the Rate Limit

Dell(conf)#qos-policy-input cpuq_1 cpu-qos

Dell(conf-qos-policy-in)#rate-police 3000 40 peak 500 40

Dell(conf-qos-policy-in)#exit

Dell(conf)#qos-policy-input cpuq_2 cpu-qos

Dell(conf-qos-policy-in)#rate-police 5000 80 peak 600 50

Dell(conf-qos-policy-in)#exit

Example of Assigning a QoS Policy to a CPU Queue

Dell(conf)#policy-map-input cpuq_rate_policy cpu-qos

Dell(conf-qos-policy-in)#service-queue 5 qos-policy cpuq_1

Dell(conf-qos-policy-in)#service-queue 6 qos-policy cpuq_2

Dell(conf-qos-policy-in)#service-queue 7 qos-policy cpuq_1

Example of Applying a Queue-Based Rate Limit to Control Plane Traffic

Dell(conf)#control-plane-cpuqos

Dell(conf-control-plane)#service-policy rate-limit-cpu-queues cpuq_rate_policy

The CLI provides show commands to display the protocol traffic assigned to each control-plane queue and

the current rate-limit applied to each queue. Other show commands display statistical information for trouble

shooting CoPP operation.

Viewing Queue Rates

To view the rates that are currently applied on each control-plane queue, use the show cpu-queue rate

[all | queue-id id | range from-queue to-queue] command.

Dell#show cpu-queue rate all
