Description: Huawei L2TP extension MIB providing additional L2TP tunnel and session management objects beyond the standard L2TP MIB for Huawei devices.
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-L2TP-EXT-MIB?
HUAWEI-L2TP-EXT-MIB provides Huawei-specific extensions to L2TP (Layer 2 Tunneling Protocol) tunnel and session management, supplementing the standard L2TP MIB with additional configuration and status objects for Huawei devices. It exposes extended tunnel and session-level objects covering properties not captured by the base L2TP MIB, likely including tunnel state, session counts, and Huawei-specific L2TP feature configuration. Its monitoring relevance is to the software/protocol state of VPN tunneling services: administrators would track the number of active L2TP tunnels and sessions and their operational state to confirm remote-access or L2TP-based VPN services are functioning, and to detect tunnel flapping or session establishment failures. It explicitly extends the standard IETF L2TP MIB, depending on that base module's tunnel/session indexing conventions. It is deployed on Huawei broadband access routers and VPN gateways that terminate L2TP tunnels for remote-access or wholesale broadband aggregation services. Engineers can download the HUAWEI-L2TP-EXT-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-L2TP-EXT-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 broadband access routers
- Huawei VPN gateways (L2TP LAC/LNS)
Monitoring Examples
An administrator would poll the extended L2TP tunnel and session tables to check active tunnel count and session state for a given LNS/LAC pairing, verifying tunnels remain established during peak usage. A drop in active session count combined with rising tunnel-teardown events would indicate an authentication or network-path problem affecting L2TP-based remote access. No concrete sample object names were available in the source data for this MIB.
What Can Be Monitored
- active L2TP tunnel count
- active L2TP session count
- L2TP tunnel operational state
- L2TP extended feature configuration
