hmNetPTPGrandmasterUUID
Module: HMPRIV-MGMT-SNMP-MIB
OID (symbolic): HMPRIV-MGMT-SNMP-MIB::hmNetPTPGrandmasterUUID
OID (numeric): 1.3.6.1.4.1.248.14.2.3.40.1.21
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: The UUID of its Grandmaster. For Ethernet this is the MAC address of the management agent.
What is hmNetPTPGrandmasterUUID?
This OID holds the network address (MAC address) of the primary time source that this device is using for clock synchronization via Precision Time Protocol. The value identifies which device on the network is providing the authoritative time reference. A network operator checks this to verify that devices are synchronized to the correct master time source, especially in systems where timing precision is critical.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.14.2.3.40.1.21 snmpwalk -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmNetPTPGrandmasterUUID
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.14.2.3.40.1.21.1 snmpget -v2c -c public <target> HMPRIV-MGMT-SNMP-MIB::hmNetPTPGrandmasterUUID.1
