Description: An indication of what version of the Spanning Tree Protocol is being run. The value 'decLb100(2)' indicates the DEC LANbridge 100 Spanning Tree protocol. IEEE 802.1d implementations will return 'ieee8021d(3)'. If future versions of the IEEE Spanning Tree Protocol are released that are incompatible with the current version a new value will be defined.

What is mBrdgStpProtocolSpecification?

This value reports which Spanning Tree Protocol version a specific bridge entity is running: unknown, DEC LANbridge 100, or IEEE 802.1D. An admin checks this to confirm a bridge is running standard 802.1D STP before assuming interoperability with other vendors' switches.
