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.
