Module: ACE20-MIB

OID (symbolic): ACE20-MIB::atmCbrCnfgLastChange

OID (numeric): 1.3.6.1.4.1.164.12.4.3.3.1.1.7

Node type: OBJECT-TYPE

Type: TimeStamp

Access: read-only

Description: The value of sysUpTime at the time the ATM to CBR connection entered its mandatory operational state. If the mandatory 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 ( Atm2Cbr and Cbr2Atm ).

What is atmCbrCnfgLastChange?

This OID records the device's system uptime (sysUpTime value) at the exact moment when the ATM CBR connection transitioned to its operational state, measured in hundredths of a second. Engineers use this timestamp to correlate connection bring-ups with other network events, diagnose service flaps, or verify when a circuit came online. A value of 12345600 indicates the connection entered service roughly 142 days after the device last started up.
