ctBridgeStpProtocolSpecification
Module: CTRON-BRIDGE-MIB
OID (symbolic): CTRON-BRIDGE-MIB::ctBridgeStpProtocolSpecification
OID (numeric): 1.3.6.1.4.1.52.4.1.2.3.2.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object allows the network manager to select which Spanning Tree Protocol will be operational on the bridge. The value 'decLb100(2)' indicates the DEC LANbridge 100 Spanning Tree protocol. The value 'ieee8021d(3)' indicates the IEEE 802.1d Spanning Tree Protocol. The value 'none(1)' indicates no Spanning Tree Protocol is operational.
What is ctBridgeStpProtocolSpecification?
This read-write enumerated integer lets an administrator choose which Spanning Tree Protocol variant the bridge runs: none(1) for no spanning tree, decLb100(2) for the DEC LANbridge 100 protocol, or ieee8021d(3) for standard IEEE 802.1D STP. Setting this correctly is essential because it determines whether the bridge actively participates in loop prevention, and a mismatch with attached devices' protocol expectations can leave a network unprotected against bridging loops. For example, when replacing a legacy DEC LANbridge with a modern topology, the admin changes this from decLb100(2) to ieee8021d(3) to align with standards-based switches elsewhere in the network.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.3.2.1 snmpwalk -v2c -c public <target> CTRON-BRIDGE-MIB::ctBridgeStpProtocolSpecification
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.2.3.2.1.1 snmpget -v2c -c public <target> CTRON-BRIDGE-MIB::ctBridgeStpProtocolSpecification.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.2.3.2.1.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ctBridgeStpProtocolSpecification.1
