tfAlarmLastChanged
Module: TAILF-ALARM-MIB
OID (symbolic): TAILF-ALARM-MIB::tfAlarmLastChanged
OID (numeric): 1.3.6.1.4.1.24961.2.103.1.1.2
Node type: OBJECT-TYPE
Type: DateAndTime
Access: read-only
Description: A timestamp when the active alarm table was last changed. The value can be used by a manager to initiate an alarm resynchronization procedure. NOTE: All fields of the DateAndTime MUST be filled out, including the hours and minutes from UTC. As such, the value should be 11 octets long.
What is tfAlarmLastChanged?
Holds an 11-octet DateAndTime timestamp of the last time the active alarm table changed, including UTC offset. A manager can poll this value and, when it changes, trigger an alarm resynchronization procedure instead of continuously walking the full table. For example, if this timestamp advances since the last poll, the NMS knows to re-fetch tfAlarmTable to pick up new or updated alarm rows.
