◆ When a ARP entry expires, it is deleted from the cache and an ARP
request packet is sent to re-establish the MAC address.
◆ The aging time determines how long dynamic entries remain in the
cache. If the timeout is too short, the router may tie up resources by
repeating ARP requests for addresses recently flushed from the table.
E XAMPLE
This example sets the ARP cache timeout for 15 minutes (i.e., 900
seconds).
Console(config)#arp timeout 900
