Dell(conf-class-map-cpuqos)#match ipv6 access-group ospfv3
4 Create a QoS input policy map to match to the class-map and qos-policy for each desired protocol.
CONFIGURATION mode
Dell(conf)#policy-map-input ospfv3_policy cpu-qos
Dell(conf-policy-map-in-cpuqos)#class-map ospfv3 qos-policy ospfv3_rate
5 Enter Control Plane mode.
CONFIGURATION mode
Dell(conf)#control-plane-cpuqos
6 Assign the protocol based service policy on the control plane. Enabling this command on a port-pipe
automatically enables the ACL and QoS rules created with the cpu-qos keyword.
CONTROL-PLANE mode
Dell(conf-control-cpuqos)#service-policy rate-limit-protocols ospfv3_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.
