CONFIGURATION mode
ipv6 access-list name cpu-qos
permit {bgp | icmp | vrrp}
4
Create a QoS input policy for the router and assign the policing.
CONFIGURATION mode
qos-policy-input name
cpu-qos rate-police rate-police-value
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
Examples of Configuring CoPP for Different Protocols
The following example shows creating the IP/IPv6/MAC extended ACL.
Dell(conf)#ip access-list extended ospf cpu-qos
Dell(conf-ip-acl-cpuqos)#permit ospf
Dell(conf-ip-acl-cpuqos)#exit
Dell(conf)#ip access-list extended bgp cpu-qos
Dell(conf-ip-acl-cpuqos)#permit bgp
Dell(conf-ip-acl-cpuqos)#exit
Dell(conf)#mac access-list extended lacp cpu-qos
Dell(conf-mac-acl-cpuqos)#permit lacp
Dell(conf-mac-acl-cpuqos)#exit
Dell(conf)#ipv6 access-list ipv6-icmp cpu-qos
Dell(conf-ipv6-acl-cpuqos)#permit icmp
Dell(conf-ipv6-acl-cpuqos)#exit
Dell(conf)#ipv6 access-list ipv6-vrrp cpu-qos
Dell(conf-ipv6-acl-cpuqos)#permit vrrp
Dell(conf-ipv6-acl-cpuqos)#exit
