Usage Guide 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
unless there is a special requirement.
Configuration
Examples
The following example sets the timeout for the dynamic ARP mapping record that is learned
dynamically from FastEthernet port 0/1 to 120 seconds.
Ruijie(config)# interface fastEthernet 0/1
Ruijie(config-if)# arp timeout 120
