The default timeout value is 20 minutes.

Level: 8
The ARP timeout setting is only applicable to the IP address and the MAC address
mapping that are learned dynamically. The shorter the timeout, the truer the mapping
table saved in the ARP cache, but the more network bandwidth occupied by the
ARP. Hence the advantages and disadvantages should be weighted. Generally it is
not necessary to configure the ARP timeout too shorter unless there is a special
requirement.
Users can verify the settings by entering the show arp timeout command.
This example shows how to tonfigure the timeout value, for the dynamic ARP
mapping record, to 120 minutes.
This example shows how to restore the timeout value, for the dynamic ARP mapping
record, to 20 minutes.
