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
