Description: Monitors L2TP tunnel sessions and configuration on bintec elmeg BIANCA/BRICK broadband routers.

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 BIANCA-BRICK-L2TP-MIB?

BIANCA-BRICK-L2TP-MIB is a vendor-specific MIB for bintec elmeg's BIANCA/BRICK line of broadband routers, focused on Layer 2 Tunneling Protocol (L2TP) tunnel and session management. It exposes tunnel and session tables covering configuration parameters and operational state for L2TP tunnels terminated on the router. It is used to monitor the software/protocol status of VPN and remote-access connectivity — specifically whether a tunnel is up or down and how many sessions are currently active within it — which is critical for diagnosing lost remote-access connectivity. It conceptually depends on the standard L2TP protocol (RFC 2661) that the proprietary tables reflect. It's typically deployed in broadband/ISP access aggregation or branch-office VPN scenarios where BIANCA/BRICK routers act as an L2TP access concentrator (LAC) or network server (LNS). Engineers can download the BIANCA-BRICK-L2TP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BIANCA-BRICK-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

No sample object or table names were retrievable for this MIB, so a concrete polling example can't be grounded in real identifiers. In general, an L2TP MIB of this kind would be polled for per-tunnel operational state and active session count, which an operator would use to detect a dropped L2TP tunnel that has taken down all of its downstream PPP sessions.

What Can Be Monitored

L2TP tunnel operational state
active L2TP session count per tunnel
tunnel/session configuration parameters

INT l2tpGlobPortUsage	1.3.6.1.4.1.272.4.23.8.10.20	INTEGER	read-write	This object specifies whether L2TP uses only one UDP port (which number is defined by l2tpGlobUdpPort), or if it allocates a new available port, to send messages to the remote equipment. Choosing 'single' makes it sometimes easier to process L2TP through NAT since L2TP traffic can be classified based on the UDP port number. Choosing 'floating' selects the behavior which is recommended in RFC2331. Possible values: single(1), -- L2TP uses the UDP port defined by l2tpGlobUdpPort -- to send messages to the remote equipment. floating(2) -- L2TP allocates a new port to send messages to -- the remote equipment (default).
