swPTPGrandmasterIdentity
Module: PTP-MIB
OID (symbolic): PTP-MIB::swPTPGrandmasterIdentity
OID (numeric): 1.3.6.1.4.1.171.12.94.1.5.1.1.3
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: This indicates the PTP grandmaster identity.
What is swPTPGrandmasterIdentity?
A read-only 8-octet clock identity of the grandmaster clock currently governing this unit's PTP domain. Admins use this to confirm which physical clock, potentially several hops away, is the ultimate time source for the network.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.5.1.1.3 snmpwalk -v2c -c public <target> PTP-MIB::swPTPGrandmasterIdentity
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.12.94.1.5.1.1.3.1 snmpget -v2c -c public <target> PTP-MIB::swPTPGrandmasterIdentity.1
