cache. Use the no form to restore the default timeout.
Syntax
arp timeout seconds

Command Mode

Command Usage
• 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.
Example
This example sets the ARP cache timeout for 15 minutes (i.e., 900 seconds).
Console(config)#arp timeout 900
Console(config)#
ip proxy-arp
This command enables proxy Address Resolution Protocol (ARP). Use the no form to disable proxy
ARP.
