a3ComSysBridgeLoopDetectMode
Module: A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB
OID (symbolic): A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeLoopDetectMode
OID (numeric): 1.3.6.1.4.1.43.29.4.10.2.1.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object determines the behavior of loop detection
enabled(1) - The DA will detect loops and disable the apporiate port. disabled(2) - No loop detection mechanism will be enabled. immediate(3) - If a BPDU is received on a front panel port then a front panel port will be disabled. The default value for this object disabled(2).
What is a3ComSysBridgeLoopDetectMode?
Configures loop detection: enabled(1) detects and disables looped ports, immediate(3) kills ports on BPDU receipt, disabled(2) skips checks. Engineers enable this to auto-isolate redundant paths causing broadcast storms. immediate(3) is aggressive; enabled(1) is safer.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.21 snmpwalk -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeLoopDetectMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.43.29.4.10.2.1.21.1 snmpget -v2c -c public <target> A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB::a3ComSysBridgeLoopDetectMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.43.29.4.10.2.1.21.1 i <value>
