Module: IEEE8021-SPANNING-TREE-MIB
OID (symbolic): IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeProtocolSpecification
OID (numeric): 1.3.111.2.802.1.1.3.1.1.1.2
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)'. New enumerated values may be added in the future to the definition of this object to reflect future versions of the IEEE Spanning Tree protocol.
What is ieee8021SpanningTreeProtocolSpecification?
Which flavor of Spanning Tree Protocol this bridge is running — legacy DEC LANbridge 100, IEEE 802.1D, or IEEE 802.1Q — useful for confirming a switch is actually running the protocol version your topology design assumes.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.3.1.1.1.2 snmpwalk -v2c -c public <target> IEEE8021-SPANNING-TREE-MIB::ieee8021SpanningTreeProtocolSpecification
Get a specific instance (index 1):
