Consequently, 1 kbps is roughly equivalent to 2 pps.The basics for creating a CoPP service policy is to create QoS policies for the desired CPU bound queue and associate it with a particularrate-limit. The QoS policies are assigned to a control-plane service policy for each port-pipe.1 Create a QoS input policy for the router and assign the policing.CONFIGURATION modeqos-policy-input name cpu-qos2 Create an input policy-map to assign the QoS policy to the desired service queues.l.CONFIGURATION modepolicy-map--input namecpu-qos service-queue queue-number qos-policy name3 Enter Control Plane mode.CONFIGURATION modecontrol-plane-cpuqos4 Assign a CPU queue-based service policy on the control plane in cpu-qos mode.
