Module: CTRMONXT-MIB
OID (symbolic): CTRMONXT-MIB::ctDiscoveryNMCreationTime
OID (numeric): 1.3.6.1.4.1.52.4.3.2.20.4.1.4
Node type: OBJECT-TYPE
Type: TimeTicks
Access: read-only
Description: The value of SysUpTime when an error free frame with this source MAC/Network address association was detected, and an entry with a corresponding association was not present in the ctDiscoveryNMTable.
What is ctDiscoveryNMCreationTime?
This TimeTicks value records the device's sysUpTime at the moment this particular MAC/Network address pairing was first seen in an error-free frame and added as a new entry. It lets an admin determine exactly when a host first appeared on the segment, which is useful for spotting newly connected or newly active devices. For example, comparing ctDiscoveryNMCreationTime against the current sysUpTime tells an admin how long ago a suspicious new MAC address first showed up on the monitored network.
