Description: Emulated LAN MIB providing management objects for ATM-based ELAN services including LAN emulation clients and servers.

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 ELAN-MIB?

ELAN-MIB is a vendor-neutral, ATM Forum/IETF standards-based MIB module defining management objects for Emulated LAN (ELAN) services running over ATM networks, part of the classic LAN Emulation (LANE) technology area. It exposes configuration data for ELAN definitions, such as LAN type and maximum frame size, along with tables tracking LAN Emulation Server (LES) instances and their association state. Administrators use it to monitor the software status of ATM LANE components, confirming that configured ELAN instances and their LES entries are present, correctly indexed, and in an active row status, effectively giving a health/availability view of the emulation service rather than raw traffic counters. It is built on ATM Forum LAN Emulation specifications, sitting under the atmForum/atmfLanEmulation enterprise tree alongside other ATM Forum MIBs. It is typically deployed in legacy ATM campus or carrier networks where Ethernet segments were emulated over an ATM backbone. Engineers can download the ELAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ELAN-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

  • ATM LAN Emulation (LANE) switch/server
  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

An administrator polling elanConfTable/elanConfEntry rows can see each configured ELAN's elanConfName, elanConfLanType, and elanConfMaxFrameSize, and check elanConfRowStatus to confirm the configuration is active. Cross-referencing with elanLesTable/elanLesEntry indexed by elanLesIndex reveals whether the LAN Emulation Server for that ELAN is present and reachable; a missing or stale LES entry alongside a valid elanConfEntry would indicate the emulation service has failed to associate a server. This lets an operator detect ELAN misconfiguration or LES failures without inspecting raw ATM signaling.

What Can Be Monitored

  • ELAN configuration name and type
  • maximum frame size per ELAN
  • ELAN configuration row status
  • LAN Emulation Server (LES) presence
  • LES table index entries
