ieee8021AsCurrentDSTimeOfLastGmChangeEvent
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsCurrentDSTimeOfLastGmChangeEvent
OID (numeric): 1.3.111.2.802.1.1.20.1.2.12
Node type: OBJECT-TYPE
Type: TimeStamp
Access: read-only
Description: This timestamp denotes the system time when the most recent grandmaster change occurred in a gPTP domain. This timestamp is updated when the PortAnnounceInformation state machine enters the SUPERIOR_MASTER_PORT state or the INFERIOR_MASTER_OR_OTHER_PORT state (see 10.3.11 and Figure 10-13).
What is ieee8021AsCurrentDSTimeOfLastGmChangeEvent?
The sysUpTime timestamp (in 0.01s units) of the most recent grandmaster change in this gPTP domain. Correlate this with other logs to pinpoint exactly when a grandmaster failover occurred.
Examples
