hlsDot1dStpProtocolSpecification
Module: HLS-MIB
OID (symbolic): HLS-MIB::hlsDot1dStpProtocolSpecification
OID (numeric): 1.3.6.1.4.1.26.21.1.2.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: An indication of what version of the Spanning Tree Protocol is being run. Early DEC Spanning Tree implementations will return 'decprotocol(2)'. 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 hlsDot1dStpProtocolSpecification?
Reports which Spanning Tree Protocol variant this bridge is running: an early DEC implementation or standard IEEE 802.1D. Administrators check this when mixing bridges from different vendors or eras to confirm STP compatibility across the topology.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.26.21.1.2.1 snmpwalk -v2c -c public <target> HLS-MIB::hlsDot1dStpProtocolSpecification
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.26.21.1.2.1.1 snmpget -v2c -c public <target> HLS-MIB::hlsDot1dStpProtocolSpecification.1
