ctDiscoveryNMLastTransmitTime
Module: CTRMONXT-MIB
OID (symbolic): CTRMONXT-MIB::ctDiscoveryNMLastTransmitTime
OID (numeric): 1.3.6.1.4.1.52.4.3.2.20.4.1.5
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: The value of SysUpTime when this entry was last updated. This time correponds to the last time that a frame with the source MAC/Network association of this dicovery entry was detected. This object is useful in that the management station can compute idle time by the difference between this value and current sysUpTime.
What is ctDiscoveryNMLastTransmitTime?
This TimeTicks value stores the sysUpTime at which a frame carrying this entry's source MAC/Network association was most recently detected, i.e., when the row was last refreshed. As the description notes, a management station can subtract this value from the current sysUpTime to calculate how long the associated host has been idle. For example, if ctDiscoveryNMLastTransmitTime stopped advancing hours ago while sysUpTime keeps climbing, an admin can conclude that host has gone quiet or disconnected.
