Command Mode Global Configuration mode User Guidelines The software uses ARP cache entries to translate 32-bit IP addresses into 48-bit hardware addresses. Because most hosts support dynamic resolution, static ARP cache entries do not need to be specified. Example The following example adds the IP address 198.133.219.232 and MAC address 00-00-0c-40-0f-bc to the ARP table. Console (config)# arp 198.133.219.232 0000.0c40.0fbc ethernet g8 arp timeout The arp timeout global configuration command configures how long an entry remains in the ARP cache. To restore the default value, use the no form of this command. Syntax arp timeout seconds no arp timeout seconds • seconds-Time (in seconds) that an entry remains in the ARP cache.

Command Mode Global Configuration mode User Guidelines It is recommended not to set the timeout value to less than 3600. NOTE: The ARP entry is deleted between the period of the "timeout value" and twice the "timeout value". For example, if the timeout value is 20 seconds, the ARP value is deleted during the period of 20 to 40 seconds. Example The following example configures ARP timeout to 12000 seconds.
