Module: A3COM-HUAWEI-EPON-MIB
OID (symbolic): A3COM-HUAWEI-EPON-MIB::h3cEponPortLoopBackAlmEnable
OID (numeric): 1.3.6.1.4.1.43.45.1.10.2.42.1.1.8
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: LoopBack alarm behavior of EPON ports. true(1) - alarm enable. false(2) - alarm disable.
What is h3cEponPortLoopBackAlmEnable?
This boolean OID enables alarms when EPON ports detect loopback conditions, indicating a potential cabling problem. Network engineers use this to catch physical port misconfigurations where traffic loops back on itself. Enabling it alerts staff to dangerous network loops that could cause broadcast storms.
Examples
