ieee8021AsParentDSParentClockIdentity
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsParentDSParentClockIdentity
OID (numeric): 1.3.111.2.802.1.1.20.1.3.1
Node type: OBJECT-TYPE
Type: ClockIdentity
Access: read-only
Description: Clock identifier (clockIdentity) of the local clock's parent clock. The default value is set to ieee8021AsDefaultDSClockIdentity.
If this time-aware system is the grandmaster, the value is the clockIdentity of this time-aware system. If this time-aware system is not the grandmaster, the value is the clockIdentity of the MasterPort (see Table 10-1) of the gPTP communication path attached to the single slave port of this time-aware system.
What is ieee8021AsParentDSParentClockIdentity?
The clockIdentity of this device's immediate parent clock in the gPTP hierarchy, its own identity if it is the grandmaster, or the master port's identity on the path toward the grandmaster otherwise. Use it to trace the sync topology upstream from a given device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.3.1 snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsParentDSParentClockIdentity
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.3.1.1 snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsParentDSParentClockIdentity.1
