Setup Guide

permit {arp | frrp | gvrp | isis | lacp | lldp | stp}
2 Create a Layer 3 extended ACL for control-plane trac policing for a particular protocol.
CONFIGURATION mode
ip access-list extended name cpu-qos
permit {bgp | dhcp | dhcp-relay | ftp | icmp | igmp | mcast-catch-all | msdp | ntp | ospf |
pim | ip | ssh | telnet | vrrp}
3 Create an IPv6 ACL for control-plane trac policing for a particular protocol.
CONFIGURATION mode
permit {bgp | icmp | vrrp}
4 Create a QoS input policy for the router and assign the policing.
CONFIGURATION mode
cpu-qos rate-police rate-police-value
5 Create a QoS class map to dierentiate the control-plane trac 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 Conguring CoPP for Dierent Protocols
The following example shows creating the IP/IPv6/MAC extended ACL.
DellEMC(conf)#ip access-list extended mcast cpu-qos
DellEMC(conf-ip-acl-cpuqos)#permit mcast-catch-all
DellEMC(conf-ip-acl-cpuqos)#exit
DellEMC(conf)#ip access-list extended ospf cpu-qos
DellEMC(conf-ip-acl-cpuqos)#permit ospf
DellEMC(conf-ip-acl-cpuqos)#exit
DellEMC(conf)#ip access-list extended bgp cpu-qos
DellEMC(conf-ip-acl-cpuqos)#permit bgp
DellEMC(conf-ip-acl-cpuqos)#exit
DellEMC(conf)#mac access-list extended lacp cpu-qos
DellEMC(conf-mac-acl-cpuqos)#permit lacp
DellEMC(conf-mac-acl-cpuqos)#exit
