Configuring Copp For Protocols - Dell Z9000 Configuration Manual

CoPP policies are configured by creating extended ACL rules and specifying rate-limits through QoS
policies. The ACLs and QoS policies are assigned as service-policies.

Configuring CoPP for Protocols

This section lists the commands necessary to create and enable the service-policies for CoPP.
For complete information about creating ACLs and QoS rules, refer to
Quality of Service (QoS).
The basics for creating a CoPP service policy are to create a Layer 2, Layer 3, and/or an IPv6 ACL rule for
the desired protocol type. Then, create a QoS input policy to rate-limit the protocol traffics according to
the ACL. The ACL and QoS policies are finally assigned to a control-plane service policy for each port-
pipe.
1. Create a Layer 2 extended ACL for control-plane traffic policing for a particular protocol.
CONFIGURATION mode
mac access-list extended name cpu-qos permit {arp | frrp | gvrp | isis |
lacp | lldp | stp}
2. Create a Layer 3 extended ACL for control-plane traffic policing for a particular protocol.
CONFIGURATION mode
ip access-list extended name cpu-qos permit {bgp | dhcp | dhcp-relay | ftp |
icmp | igmp | msdp | ntp | ospf | pim | ip | ssh | telnet | vrrp}
3. Create an IPv6 ACL for control-plane traffic policing for a particular protocol.
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
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
