usrBRStpProtocolSpecification
Module: Usr-bridge-MIB
OID (symbolic): Usr-bridge-MIB::usrBRStpProtocolSpecification
OID (numeric): 1.3.6.1.4.1.429.4.14.2.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
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 usrBRStpProtocolSpecification?
This reports which version of the Spanning Tree Protocol the bridge is running: 'unknown(1)', 'decLb100(2)' for the DEC LANbridge 100 protocol, or 'ieee8021d(3)' for standard IEEE 802.1D; admins check this to confirm STP interoperability expectations with other switches on the segment.
