Show Commands - Dell S4820T Configuration Manual

Z9000 platforms. You can use the ipv6 access-list name cpu-qos permit ospfv3 or the ipv6
access-list name cpu-qos ospfv3 command to allow CoPP traffic for OSPFv3. The control plane
management support for IPv6 ICMPv6 packets is enhanced to enable more number of CPU queues on
port to be available and other COPP improvements have been implemented.
To configure control-plane policing, perform the following:
1. Create an IPv6 ACL for control-plane traffic policing for ospfv3.
CONFIGURATION mode
Dell(conf)#ipv6 access-list ospfv3 cpu-qos
Dell(conf-ipv6-acl-cpuqos)#permit ospf
2. Create a QoS input policy for the router and assign the policing.
CONFIGURATION mode
Dell(conf)#qos-policy-input ospfv3_rate cpu-qos
Dell(conf-in-qos-policy-cpuqos)#rate-police 1500 16 peak 1500 16
3. Create a QoS class map to differentiate the control-plane traffic and assign to the ACL.
CONFIGURATION mode
Dell(conf)#class-map match-any ospfv3 cpu-qos
Dell(conf-class-map-cpuqos)#match ipv6 access-group ospfv3
4. Create a QoS input policy map to match to the class-map and qos-policy for each desired protocol.
CONFIGURATION mode
Dell(conf)#policy-map-input ospfv3_policy cpu-qos
Dell(conf-policy-map-in-cpuqos)#class-map ospfv3 qos-policy ospfv3_rate
5. Enter Control Plane mode.
CONFIGURATION mode
Dell(conf)#control-plane-cpuqos
6. Assign the protocol based service policy on the control plane. Enabling this command on a port-pipe
automatically enables the ACL and QoS rules created with the cpu-qos keyword.
CONTROL-PLANE mode
Dell(conf-control-cpuqos)#service-policy rate-limit-protocols ospfv3_policy
