Description: Huawei L2VPN OAM MIB providing operations, administration, and maintenance objects for fault detection and performance monitoring on L2VPN services.
Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.
What Is HUAWEI-L2VPN-OAM-MIB?
HUAWEI-L2VPN-OAM-MIB is a Huawei-proprietary SNMP module belonging to Huawei's carrier and enterprise networking product line, specifically covering Layer 2 VPN Operations, Administration, and Maintenance (OAM). It is primarily a notification/trap module rather than a broad set of polled tables, focused on signaling OAM-related fault and status events for L2VPN pseudowires and services. Because it is trap-oriented, its main monitoring value is alerting operators to connectivity faults, continuity-check failures, and other service-affecting events on L2VPN circuits rather than exposing continuous counters. It complements Huawei's broader L2VPN and MPLS MIBs and draws on IETF OAM/pseudowire concepts (e.g., VCCV, BFD) for its event model. It is typically deployed on Huawei routers and switches acting as PE devices in a provider's L2VPN/MPLS core, where an NMS subscribes to these traps to detect service outages quickly, and network engineers often view the HUAWEI-L2VPN-OAM-MIB MIB Browser entry for its full trap and object definitions.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-L2VPN-OAM-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Huawei carrier/enterprise routers and switches (PE devices)
Monitoring Examples
The module_desc states it simply "contains objects to manage OAM TRAP," and no runtime data tables were captured in sample_objects, so this MIB is best understood as a notification-carrying module rather than one with pollable counters. In practice an NMS would register to receive its traps to be alerted the instant an L2VPN pseudowire OAM session detects a fault (e.g., loss of continuity between PE routers), rather than by issuing GET requests against it. Because no concrete object or table names were provided in the source data, specific varbind names cannot be honestly cited here.
What Can Be Monitored
- L2VPN pseudowire fault notifications
- OAM continuity-check alarms
- L2VPN service-affecting events
