What Is CTRON-ELAN-MIB?

CTRON-ELAN-MIB is a Cabletron Systems enterprise MIB for managing Emulated LAN (ELAN) configuration used in LAN Emulation (LANE) over ATM networks, a technology that let legacy Ethernet/Token Ring traffic run over ATM backbones. It exposes configuration data for ELAN instances (per-unit ELAN policy, directory services address, deletion policy) and operational role objects for LAN Emulation Client (LEC), LAN Emulation Server (LES), and related peer discovery tables. For device monitoring it is used to confirm that ELAN configuration rows are active (via row status) and that a unit's LEC/LES/SFDS peer relationships are correctly established, revealing configuration drift or a LEC that has failed to join its ELAN rather than CPU or temperature faults. It depends on the ATM Forum LAN Emulation specifications and interacts with underlying ATM interface MIBs for the physical/virtual circuit layer. This module was deployed on Cabletron ATM edge switches and routers during the era when ATM LANE bridged legacy LANs across campus ATM cores. Engineers can download the CTRON-ELAN-MIB file directly to load it into their MIB browser.

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

LAN Emulation (LANE)-capable network device

Monitoring Examples

An administrator would poll ctElanConfTable/ctElanConfEntry, indexed by ctElanConfIndex and ctElanConfUnitNumber, to check ctElanConfPolicy and ctElanConfRowStatus for a given ELAN instance, confirming the row is active and correctly deleted per ctElanConfDelPolicyWithElan when decommissioned. The ctElanSFDSPeerTable (with ctElanSFDSPeerIP and ctElanSFDSPeerRowStatus) would be checked to verify SFDS (Simple Fault-tolerant Distributed Server) peer relationships are valid, and ctElanConfDirectoryServicesIP would be polled to confirm the unit points to the correct LAN Emulation directory server. A missing or inactive row in ctElanSFDSPeerTable would indicate a broken peer relationship preventing proper LANE address resolution.

What Can Be Monitored

ELAN configuration row status
ELAN policy per unit
ELAN directory services IP address
SFDS peer IP and row status
LEC/LES/ELAN role state

OID symbolic	OID numeric	Type	Access	Description
ctLeClient	1.3.6.1.4.1.52.4.3.5.1
ctElan	1.3.6.1.4.1.52.4.3.5.2
ctElanConfGroup	1.3.6.1.4.1.52.4.3.5.2.1
ctElanConfTable	1.3.6.1.4.1.52.4.3.5.2.1.1		not-accessible	This table defines an extension to the elanConfTable.
ctElanConfEntry	1.3.6.1.4.1.52.4.3.5.2.1.1.1		not-accessible	Each entry in this table represents an Emulated LAN. Objects elanConfIndex and elanConfRowStatus are required during row creation and deletion.
ELA ctElanConfIndex	1.3.6.1.4.1.52.4.3.5.2.1.1.1.1	ElanLocalIndex	read-only	A value which uniquely identifies a conceptual row in the ctElanConfTable. The value corresponds to elanConfIndex.
INT ctElanConfUnitNumber	1.3.6.1.4.1.52.4.3.5.2.1.1.1.2	INTEGER	read-only	Adapter unit for this ELAN, currently read-only. May expand to be read-write.
INT ctElanConfPolicy	1.3.6.1.4.1.52.4.3.5.2.1.1.1.3	INTEGER	read-write	Policy determination of this ELAN, where secure(1) ensures that cut through operation will not be in operation. When an ELAN is in secure mode, it will not allow inter-elan communication by restricting directory services learning or lookups. The secure(1) mode also restricts the bus from proxy broadcast resolution, also know as the protocol preprocessor. When in nonsecure(2) mode, the ELAN will allow cut through operation, Directory Services advertisement, and proxy broadcast resolution.
INT ctElanConfDelPolicyWithElan	1.3.6.1.4.1.52.4.3.5.2.1.1.1.4	INTEGER	read-write	This objects indicates that if an ELAN row is deleted, any existing LEC->ELAN mappings must also be deleted.
INT ctElanConfRowStatus	1.3.6.1.4.1.52.4.3.5.2.1.1.1.5	INTEGER	read-write	This object is used to create or delete entries in the elanConfTable.
ctElanSFDSPeerTable	1.3.6.1.4.1.52.4.3.5.2.1.2		not-accessible	This table contains all Secure Fast Directory Services Database IPs that have been added as peers. Creating an entry in this table will add the SFDS database at that IP as a peer. Deleting and entry in this table will drop the SFDS at that IP as a peer.
ctElanSFDSPeerEntry	1.3.6.1.4.1.52.4.3.5.2.1.2.1		not-accessible	Each entry in this table represents an SFDS Database that has been added as a peer. ctElanSFDSPeerIP and ctElanSFDSPeerRowStatus must be present during row creation and deletion.
