dot1dStpProtocolSpecification
Module: BRIDGE-MIB
OID (symbolic): BRIDGE-MIB::dot1dStpProtocolSpecification
OID (numeric): 1.3.6.1.2.1.17.2.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: STP protocol specification.
What is dot1dStpProtocolSpecification?
Identifies which version of the Spanning Tree Protocol the bridge is running, such as the DEC LANbridge 100 variant or IEEE 802.1D. This helps network managers confirm interoperability and compliance with expected STP standards.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.17.2.1 snmpwalk -v2c -c public <target> BRIDGE-MIB::dot1dStpProtocolSpecification
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.17.2.1.1 snmpget -v2c -c public <target> BRIDGE-MIB::dot1dStpProtocolSpecification.1
