a3IParpHoldTime 1.3.6.1.4.1.43.2.6.13.1.3

This object determines the amount of time, in hours, an entry can stay in the ARP table. When the specified time elapses, the entry is deleted. When one sixteenth of the time elapses, ARP considers this entry aged. When a packet is destined for an entry that has become aged, the system sends an ARP request, using a unicast address, to the destination to verify whether it is still operational. This object corresponds to the UI parameter: -arp HoldTime.
