The ARP Aging time display in the output is the period of time that indicates when an ARP entry is deleted from the ARP table. Set this value by entering the set arp agingtime command. The remaining lines of the display show the mappings of IP addresses (or IP aliases) to MAC addresses.

Use the ip_addr or the hostname options to specify a specific IP host when the ARP cache is large.
