This command is ignored when issued on interfaces that do not use ARP. The show interfaces EXEC command displays the ARP timeout value. The value follows the "Entry Timeout:" heading, as seen in this sample show interfaces display:
ARP type: ARPA, PROBE, Entry Timeout: 14400 sec
The following example sets the ARP timeout to 12000 seconds to allow entries to time out more quickly than the default:
interface ethernet 0 arp timeout 12000
| Command | Description |
