Switch(config-copp-policymap-p1)# #exit

Switch(config)#interface ethernet 1/0/1

Switch(config-if-ethernet1/0/1)# service-policy output p1

Example 2: Configure the COPP policy map on ethernet1/0/1 of Switch-1, limit the

packets of the source mac address of 00-00-11-22-33-44 as 10pps, and configure the

burst threshold as 20pps. Configure the priority as 1 and forward the packets whose

bandwidth exceeds the value.

Configuration steps:

Switch#config

Switch(config)#access-list 1100 permit host-source-mac 00-00-11-22-33-44

any-destination-mac

Switch(config)#class-map c1

Switch(config-classmap-c1)#match access-group 1100

Switch(config)#copp-policy-map p1

Switch(config-copp-policymap-p1)#class c1

COPP Configuration Troubleshooting

 If the packets which belong to this network segment went on the cpu correctly. This

function can limit the rate of the packets going on the cpu, user can check if the

packets went on the cpu through the command of debug driver receive.

 If the ACL is matched correctly. The ACL rule must be permit.

 If the COPP policy map is configured correctly. COPP must be on the egress direction

on the port, it does not support the ingress direction.
