a3ComBrgStpMultAdd
Module: A3COM-BRIDGE-R3-MIB
OID (symbolic): A3COM-BRIDGE-R3-MIB::a3ComBrgStpMultAdd
OID (numeric): 1.3.6.1.4.1.43.2.9.2.1
Node type: OBJECT-TYPE
Type: MacAddress
Access: read-only
Description: This is the multicast MAC address used by bridges running the Spanning Tree Protocol.
What is a3ComBrgStpMultAdd?
This read-only MAC address field reports the standard multicast address (01-80-C2-00-00-00) used by all bridges running the Spanning Tree Protocol for BPDU exchange. Monitoring systems verify this value to confirm STP operation is using the correct multicast group. The fixed value 01-80-C2-00-00-00 means STP uses the IEEE-reserved multicast address.
