Description: An indication of which Spanning Tree Protocol version is being run. The value 'decLb100(2)' indicates the DEC LANbridge 100 Spanning Tree protocol. IEEE 802.1d implementations 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 pgBrVlanGroupStpProtocolSpecification?

Reports which Spanning Tree Protocol variant is running for this VLAN group: unknown(1), decLb100(2) for DEC LANbridge 100, or ieee8021d(3) for standard 802.1D. Most modern deployments will report ieee8021d(3).
