s5CmNetAddrLastSeen
Module: S5-COMMON-STATS-MIB
OID (symbolic): S5-COMMON-STATS-MIB::s5CmNetAddrLastSeen
OID (numeric): 1.3.6.1.4.1.45.1.6.5.1.3.1.8
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: The value of sysUpTime at the time this network address was last seen on this interface/board/port/MAC.
What is s5CmNetAddrLastSeen?
This TimeTicks value records the sysUpTime timestamp of when this network address was last observed on the given interface/board/port/MAC combination. It lets an admin judge how fresh or stale an IP-to-MAC mapping is, which matters since the table only keeps a limited number of addresses per node and discards the oldest. For example, a large gap between this value and the current sysUpTime suggests the host hasn't been seen recently and the mapping may be outdated.
