Configuring Network Security

ARP Inspection Configurations

Step 6

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.

Step 7

end

Return to privileged EXEC mode.

Step 8

copy running-config startup-config

Save the settings in the configuration file.

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     Status        LAG

Gi1/0/2      Enabled          20        N/A             Normal       N/A

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                    LAG

Gi1/0/1      Enabled          15        N/A            Discard,290s       N/A

Gi1/0/2      Enabled          15        N/A            Normal                    N/A

......

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
