Global configuration
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 short
unless there is a special requirement.
Users can verify the settings by entering the show arp timeout command.
The following is an example of setting the timeout for the dynamic ARP mapping
record to 120 minutes:
