wfDot1dBaseBridgeAddress
Module: Wellfleet-WFDOT1D-MIB
OID (symbolic): Wellfleet-WFDOT1D-MIB::wfDot1dBaseBridgeAddress
OID (numeric): 1.3.6.1.4.1.18.3.5.1.1.6.1.1
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: The MAC address used by this bridge when it must be referred to in a unique fashion. It is recommended that this be the numerically smallest MAC address of all ports that belong to this bridge. However it is only required to be unique. When concatenated with dot1dStpPriority a unique BridgeIdentifier is formed which is used in the Spanning Tree Protocol.
What is wfDot1dBaseBridgeAddress?
This read-only OCTET STRING holds the MAC address the bridge uses to uniquely identify itself, recommended to be the numerically smallest MAC address among all its ports. It matters because, concatenated with the Spanning Tree priority, it forms the unique Bridge Identifier used in the Spanning Tree Protocol to elect the root bridge. An admin comparing spanning-tree topology output across switches would read this value to confirm which physical device a given Bridge ID corresponds to.
