switchBridgeStpProtocolSpecification

Module: SWITCH-BRIDGE-MIB

OID (symbolic): SWITCH-BRIDGE-MIB::switchBridgeStpProtocolSpecification

OID (numeric): 1.3.6.1.4.1.207.8.9.2.2.5.2.1.1.1

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 switchBridgeStpProtocolSpecification?

Which Spanning Tree Protocol variant this bridge instance is running - unknown(1), decLb100(2, DEC LANbridge 100), or ieee8021d(3) - confirming standard 802.1D STP compatibility versus a legacy variant.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.207.8.9.2.2.5.2.1.1.1
snmpwalk -v2c -c public <target> SWITCH-BRIDGE-MIB::switchBridgeStpProtocolSpecification

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.207.8.9.2.2.5.2.1.1.1.1
snmpget -v2c -c public <target> SWITCH-BRIDGE-MIB::switchBridgeStpProtocolSpecification.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> switchBridgeStpProtocolSpecification.1
