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 switch may tie up resources by
repeating ARP requests for addresses recently flushed from the table.
