Step 7
Step 8
The following example shows how to enable ARP Defend and configure the ARP inspection
limit-rate as 20 pps on port 1/0/2:
Switch#configure
Switch(config)#interface gigabitEthernet 1/0/2
Switch(config-if)#ip arp inspection
Switch(config-if)#ip arp inspection limit-rate 20
Switch(config-if)#show ip arp inspection interface gigabitEthernet 1/0/2
Port OverSpeed Rate Current
Gi1/0/2 Enabled
Switch(config-if)#end
Switch#copy running-config startup-config
The following example shows how to restore the port 1/0/1 that is in Discard status to
Normal status:
Switch#configure
Switch(config)#show ip arp inspection interface
Port OverSpeed Rate Current Status
Gi1/0/1 Enabled
Gi1/0/2 Enabled
......
Switch(config)#interface gigabitEthernet 1/0/1
Switch(config-if)#ip arp recover
Switch(config-if)#show ip arp inspection interface gigabitEthernet 1/0/1
ip arp inspection recover
(Optional) For ports which the speed of receiving ARP packets has exceeded the limit, use
this command to restore the port from Discard status to Normal status.
end
Return to privileged EXEC mode.
