CONFIGURATION mode
qos-policy-input name cpu-qos rate-police
5 Create a QoS class map to differentiate the control-plane traffic and assign to an ACL.
CONFIGURATION mode
class-map match-any name cpu-qos match {ip | mac | ipv6} access-group name
6 Create a QoS input policy map to match to the class-map and qos-policy for each desired protocol.
CONFIGURATION mode
policy-map-input name cpu-qos class-map name qos-policy name
7 Enter Control Plane mode.
CONFIGURATION mode
control-plane-cpuqos
8 Assign the protocol based the service policy on the control plane. Enabling this command on a port-
pipe automatically enables the ACL and QoS rules creates with the cpu-qos keyword.
CONTROL-PLANE mode
service-policy rate-limit-protocols
