dot1dBaseBridgeAddress
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.
