Description: Huawei BRAS L2TP MIB for managing L2TP tunnels, sessions, and LAC/LNS configuration on broadband remote access server platforms.

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-BRAS-L2TP-MIB?

HUAWEI-BRAS-L2TP-MIB is a Huawei-proprietary MIB for the L2TP (Layer 2 Tunneling Protocol) subsystem on Huawei's Broadband Remote Access Server (BRAS) platforms. It exposes configuration and status objects for L2TP tunnels and sessions, including LAC (L2TP Access Concentrator) and LNS (L2TP Network Server) role configuration used to tunnel subscriber PPP sessions across the network. Its monitoring value includes tunnel/session status and counts, letting operators track how many active tunnels and sessions exist and detect tunnel establishment failures or unexpected session drops, which reflects both software service health and subscriber-facing connectivity on the BRAS. It operates within the broader BRAS subscriber-management MIB family alongside modules like HUAWEI-BRAS-SRVCFGINTERFACE-MIB. It is deployed on Huawei BRAS platforms at ISP broadband network edges handling PPPoE/L2TP tunneled subscriber sessions. Network engineers evaluating or troubleshooting this functionality can download the HUAWEI-BRAS-L2TP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HUAWEI-BRAS-L2TP-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.

Monitoring Examples

An administrator would poll L2TP tunnel and session tables (patterned as hwL2tpTunnelTable and hwL2tpSessionTable, though not confirmed from sample objects) to track active tunnel counts between LAC and LNS peers, with a sudden drop in session count or a spike in tunnel-establishment failures indicating an upstream LNS problem or link issue. No sample_objects were provided for this module, so specific object names are inferred rather than confirmed from source.

What Can Be Monitored

active L2TP tunnel count
active L2TP session count
LAC/LNS role configuration
tunnel establishment failures
