atmEtherCnfgLastChange

Module: ACE20-MIB

OID (symbolic): ACE20-MIB::atmEtherCnfgLastChange

OID (numeric): 1.3.6.1.4.1.164.12.4.3.4.2.1.9

Node type: OBJECT-TYPE

Type: TimeStamp

Access: read-only

Description: The value of sysUpTime at the time the ATM to Ethernet connection entered its current operational state. If the current state was entered prior to the last re-initialization of the local network management subsystem, then this object contains a zero value. Same value define both direction ( Atm2Ether and Ether2Atm ).

What is atmEtherCnfgLastChange?

This OID records the system uptime timestamp at the moment the bridge last changed operational states, helping engineers track when an outage or recovery occurred. You can use this to correlate bridge state changes with network alarms or maintenance windows and diagnose intermittent connectivity issues. For example, if lastChange shows a value from 10 seconds ago, the bridge just came online or went offline.
