ctDiscoveryMNLastTransmitTime
Module: CTRMONXT-MIB
OID (symbolic): CTRMONXT-MIB::ctDiscoveryMNLastTransmitTime
OID (numeric): 1.3.6.1.4.1.52.4.3.2.20.3.1.5
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 ctDiscoveryMNLastTransmitTime?
This read-only TimeTicks value records sysUpTime at the moment this entry was last updated, corresponding to the last frame seen with this MAC/network association, letting an admin compute idle time by comparing it to the current sysUpTime. An admin uses it to identify devices that have gone quiet on the network. For example, subtracting ctDiscoveryMNLastTransmitTime from the current sysUpTime tells the admin a device has been silent on the network for the past two hours.
