Configuring the ARP Aging on a Specific Interface

The following task overrides the global ARP aging time.

Specify the interface to be configured in interface mode.
```
device(config)# interface ethernet 1/1/1 
```

Enter the ip arp-age command followed by the aging time in minutes.
```
device(config-if-e1000-1/1/1)# ip arp-age 30 
```

The following example configures ARP aging time to 30 minutes on Ethernet interface 1/1/1.

device# configure terminal
device(config)# interface ethernet 1/1/1
device(config-if-e1000-1/1/1)# ip arp-age 30
