copp traffic-class

Description

Enables control plane policing for the specified traffic class. The no form of this command disables control plane policing.

Command context

config

Parameters

<traffic-class-type>

Specifies the traffic class type.

all

Specifies control plane policing for all traffic classes.

bgp

Specifies control plane policing for BGP control packets.

broadcast

Specifies control plane policing for broadcast packets.

exception-notification

Specifies control plane policing for MAC security, IP security flow and host.

icmp-redirect

Specifies control plane policing for ICMP redirect packets.

ip-gateway-control

Specifies control plane policing for VRRP traffic.

layer2-control-others

Specifies control plane policing for LLDP, LACP, and 802.1x.

loop-protect

Specifies control plane policing for loop-protect control packets.

mac-notification

Specifies control plane policing for MAC learn and move notifications.

multicast-route-control

Specifies control plane policing for IGMP, MLD, and PIM control packets.

multicast-sw-forward

Specifies control plane policing for IGMP data driven and multicast routing unknown flows.

mvrp

Specifies control plane policing for MVRP control packets.

ospf

Specifies control plane policing for OSPF control packets.

pvst

Specifies control plane policing for PVST packets.

rip

Specifies control plane policing for RIP control packets.

sampling

Specifies control plane policing for SFLOW.

smart-links

Specifies control plane policing for smart link control packets.

station-arp

Specifies control plane for the traffic class that applies to all ARP and ND packets reaching the switch.

station-icmp

Specifies control plane policing for the traffic class that applies to all ICMP and ICMPv6 packets reaching the switch.

station-ip

Specifies control plane policing for the traffic-class that applies to all ip and ipv6 (for example, telnet, snmp, http, ftp and other services enabled on the switch) traffic reaching the switch.

udld-control

Specifies control plane policing for UDLD and DLDP control packets.

unclassified

Specifies control plane policing for various other protocol packets copied to the switch.

unicast-sw-forward

Specifies control plane policing for unknown IP destination packets to be routed.

limit {default | <VALUE>}

Specifies the rate limit value in packets per second. See Traffic class limits.

NOTE:

The limit applies on a per-slot basis. For example, for a limit of 100 packets per second on a 5400R switch with six slots, the packets reaching the CPU will be 100 x 6, or 600 packets per second at most.

Example

Enable control plane policing for icmp traffic:

switch(config)# copp traffic-class station-icmp limit default

Example

Limit mac-learns or move notifications copied to the CPU to 128 packets per second on each slot (slave cards or interface modules):

switch(config)# copp traffic-class mac-notificaiton limit 128
