2 Create an input policy-map to assign the QoS policy to the desired service queues.l.
CONFIGURATION mode

cpu-qos service-queue queue-number qos-policy name
3 Enter Control Plane mode.
CONFIGURATION mode
control-plane-cpuqos
4 Assign a CPU queue-based service policy on the control plane in cpu-qos mode. Enabling this
command sets the queue rates according to those configured.

Examples of Configuring CoPP for CPU Queues
The following example shows creating the QoS policy.
Dell#conf
Dell(conf)#qos-policy-input cpuq_1
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
Dell(conf-qos-policy-in)#rate-police 5000 80 peak 600 50
Dell(conf-qos-policy-in)#exit
The following example shows assigning the QoS policy to the queues.
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
The following example shows creating the control plane service policy.
Dell#conf
Dell(conf)#control-plane
Dell(conf-control-plane)#service-policy rate-limit-cpu-queues cpuq_rate_policy
Displaying CoPP Configuration
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.
To view the rates for each queue, use the show cpu-queue rate cp command.
