To configure control-plane policing, perform the following:1. Create an IPv6 ACL for control-plane traffic policing for ospfv3.CONFIGURATION modeDell(conf)#ipv6 access-list ospfv3 cpu-qosDell(conf-ipv6-acl-cpuqos)#permit ospf2. Create a QoS input policy for the router and assign the policing.CONFIGURATION modeDell(conf)#qos-policy-input ospfv3_rate cpu-qosDell(conf-in-qos-policy-cpuqos)#rate-police 1500 16 peak 1500 163. Create a QoS class map to differentiate the control-plane traffic and assign to the ACL.CONFIGURATION modeDell(conf)#class-map match-any ospfv3 cpu-qosDell(conf-class-map-cpuqos)#match ipv6 access-group ospfv34. Create a QoS input policy map to match to the class-map and qos-policy for each desired protocol.CONFIGURATION modeDell(conf)#policy-map-input ospfv3_policy cpu-qosDell(conf-policy-map-in-cpuqos)#class-map ospfv3 qos-policy ospfv3_rate5. Enter Control Plane mode.CONFIGURATION modeDell(conf)#control-plane-cpuqos6. Assign the protocol based service policy on the control plane. Enabling this command on a port-pipeautomatically enables the ACL and QoS rules created with the cpu-qos keyword.CONTROL-PLANE modeDell(conf-control-cpuqos)#service-policy rate-limit-protocols ospfv3_policyShow CommandsThe following section describes the CoPP show commands.To view the rates for each queue, use the show cpu-queue rate cp command.Example of Viewing Queue RatesDell#show cpu-queue rate cpService-Queue Rate (PPS)-------------- -----------Q0 1300Q1 300Q2 300Q3 300Q4 2000Q5 400Q6 400246 Control Plane Policing (CoPP)
