rxr1dStpProtocolSpecification
Module: IBM-RXR-MIB
OID (symbolic): IBM-RXR-MIB::rxr1dStpProtocolSpecification
OID (numeric): 1.3.6.1.4.1.2.6.26.1.2.1
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 rxr1dStpProtocolSpecification?
Reports which Spanning Tree Protocol variant this bridge is running: ieee8021d(3) for the standard IEEE 802.1D STP most modern networks use, or decLb100(2) for the older, incompatible DEC LANbridge 100 STP. An admin checks this when mixing bridges from different vendors to make sure they'll actually interoperate on the same spanning tree.
