dot1dPortGmrpLastPduOrigin
Module: P-BRIDGE-MIB
OID (symbolic): P-BRIDGE-MIB::dot1dPortGmrpLastPduOrigin
OID (numeric): 1.3.6.1.2.1.17.6.1.4.1.1.3
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: The Source MAC Address of the last GMRP message received on this port.
What is dot1dPortGmrpLastPduOrigin?
This object records the source MAC address found in the most recent GMRP (GARP Multicast Registration Protocol) message received on this bridge port. A network administrator checks this to identify which device on the wire is actively sending multicast group registration updates on that port, useful when diagnosing unexpected multicast forwarding behavior. For example, dot1dPortGmrpLastPduOrigin showing a MAC address belonging to an IPTV set-top box confirms that device is the one driving GMRP registrations on that port.
