How Cisco represent Arp entry's aging time in SNMP MIB

[xhu000001]

Hi there,

I found : when a laptop roamed between an office and a meeting room and used two different IP addressed in these two places, there are two active IP arp entry in Cisco with different aging time.

Please see the screenshot for "sh ip arp".  My question is how Cisco represent the aging time in SNMP MIB. Is there any cisco proprieatry MIB to represent the aging. I want find the latest arp entry from SNMP. I can't see any useful field in ipNetToMediaEntry, ipNetToPhysicalEntry and cInetNetToMediaEntry. 

Not sure if cInetNetToMediaLastUpdated is related, but I have never get any snmpwalk result from this oid yet.

This value is not available via SNMP.

This information comes via IP-MIB and the IP-MIB's ipNetToMedia table will just give you the hardware address, network address, associated interface, and entry type (e.g. static, dynamic, etc.).
