a3IParpHoldTime
Module: A3COM-IPEXTNS-R5-MIB
OID (symbolic): A3COM-IPEXTNS-R5-MIB::a3IParpHoldTime
OID (numeric): 1.3.6.1.4.1.43.2.6.13.1.3
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: 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.
What is a3IParpHoldTime?
This read-write integer (1 to 24 hours) specifies how long ARP cache entries remain valid before deletion. One-sixteenth of this time marks an entry as 'aged', triggering unicast verification requests. A typical value of 4 hours means aged entries are refreshed every 15 minutes to confirm host reachability.
