ieee8021AsParentDSGrandmasterClockClass
Module: IEEE8021-AS-MIB
OID (symbolic): IEEE8021-AS-MIB::ieee8021AsParentDSGrandmasterClockClass
OID (numeric): 1.3.111.2.802.1.1.20.1.3.5
Node type: OBJECT-TYPE
Type: IEEE8021ASClockClassValue
Access: read-only
Description: Denotes the traceability of the time or frequency of the grandmaster. The default value is set to ieee8021AsDefaultDSClockClass.
What is ieee8021AsParentDSGrandmasterClockClass?
The clockClass (traceability rating) of the current grandmaster, mirroring ieee8021AsDefaultDSClockClass but reported for whichever device is presently grandmaster. Useful for confirming the network is being timed by a suitably trustworthy source.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.20.1.3.5 snmpwalk -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsParentDSGrandmasterClockClass
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.20.1.3.5.1 snmpget -v2c -c public <target> IEEE8021-AS-MIB::ieee8021AsParentDSGrandmasterClockClass.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ieee8021AsParentDSGrandmasterClockClass.1
