hwdot1sMstiPortLoopGuard
Module: A3COM-HUAWEI-LswMSTP-MIB
OID (symbolic): A3COM-HUAWEI-LswMSTP-MIB::hwdot1sMstiPortLoopGuard
OID (numeric): 1.3.6.1.4.1.43.45.1.2.23.1.14.20.1.27
Node type: OBJECT-TYPE
Type: EnabledStatus
Access: read-write
Description: Whether the loop protection is enabled. Effective in CIST.
What is hwdot1sMstiPortLoopGuard?
This writable boolean detects unidirectional link failures by monitoring BPDU arrival; port blocks if BPDUs stop. Prevents loops from failed links. Example: enabled to detect broken fiber where one direction fails.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.45.1.2.23.1.14.20.1.27 snmpwalk -v2c -c public <target> A3COM-HUAWEI-LswMSTP-MIB::hwdot1sMstiPortLoopGuard
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.45.1.2.23.1.14.20.1.27.1 snmpget -v2c -c public <target> A3COM-HUAWEI-LswMSTP-MIB::hwdot1sMstiPortLoopGuard.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.45.1.2.23.1.14.20.1.27.1 s <value>
