Description: IBM MIB for Emulated LAN (ELAN) management providing ATM LAN emulation service configuration and statistics.

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 IBM-ELAN-MIB?

IBM-ELAN-MIB is an IBM MIB for managing Emulated LAN (ELAN) services on ATM LAN Emulation networks, covering LES (LAN Emulation Server) and LECS (LAN Emulation Configuration Server) configuration. It exposes tables describing backup LES assignments per ELAN, LECS configuration parameters (burned-in versus configured ESI/selector values), and bandwidth/traffic-shaping parameters for ATM interfaces. Its monitoring value is largely around service configuration and availability rather than physical sensors: an admin can confirm whether a backup LES failover path is properly configured, and check the underlying ATM line speed to verify the interface is running at its expected rate. It builds on the ATM Forum's LAN Emulation (LANE) specifications and standard ATM interface conventions for physical-layer parameters. It was typically deployed in legacy enterprise ATM backbone networks bridging Ethernet LANs over ATM infrastructure, a technology largely superseded by native Ethernet/IP. Network engineers evaluating or troubleshooting this functionality can download the IBM-ELAN-MIB file directly to load it into their MIB browser.

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

IBM ATM LAN Emulation switch/server (LES/LECS)

Monitoring Examples

Polling ibmElanLesTable/ibmElanLesEntry with ibmBackupLesAtmAddrValid/ibmBackupLesAtmAddr confirms whether a backup LES is properly configured for a given ELAN, while ibmLecsConfTable entries (lecsConfiguredEsi, lecsConfiguredSelector) verify LECS addressing; an unexpected atmDevLineSpeed value would reveal an ATM interface not running at its provisioned rate.

What Can Be Monitored

backup LES configuration validity
LECS ESI/selector configuration

OID symbolic	OID numeric	Type	Access	Description
ibmElanMIB	1.3.6.1.4.1.2.6.118.1.2.1.4

ibmElanLesTable	1.3.6.1.4.1.2.6.118.1.2.1.4.2.2		not-accessible	This table contains configuration information for the all LESs for each ELAN specified in the elanConfTable. This table is used by the LECS to know if a backup LES is configured.
ibmElanLesEntry	1.3.6.1.4.1.2.6.118.1.2.1.4.2.2.1		not-accessible	Each entry represents a LES/Emulated LAN pair this agent maintains.
T/F ibmBackupLesAtmAddrValid	1.3.6.1.4.1.2.6.118.1.2.1.4.2.2.1.1	TruthValue	read-write	When True specifies the backup LES is specified by ibmBackupLesAtmAddr. When False specifies no backup LES is configured.
ADR ibmBackupLesAtmAddr	1.3.6.1.4.1.2.6.118.1.2.1.4.2.2.1.2	AtmLaneAddress	read-write	The ATM address of the backup LES.
ibmElanLecsGroup	1.3.6.1.4.1.2.6.118.1.2.1.4.3
ibmElanLecsConfGroup	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1
ibmLecsConfTable	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1		not-accessible	This table contains configuration information the LECSs within the scope of the agent.
ibmLecsConfEntry	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1		not-accessible	Each entry represents a LECS this agent maintains. Objects lecsUseBurnedInEsi, lecsConfiguredEsi, and lecsConfiguredSelector cannot be modified unless the lecsAdminStatus is set to down(2). And the change doesn't take effect until the lecsAdminStatus is set to up(1).
T/F lecsUseBurnedInEsi	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.1	TruthValue	read-write	Specifies whether a MAC Address burned into the ATM device should be used as the End System Identifier component of the LECS ATM Address.
ATM lecsConfiguredEsi	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.2	AtmPrivateAddrEsi	read-write	Locally Administered End System Identifier that is to be used as the ESI component of the LECS's ATM Address.
ATM lecsConfiguredSelector	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.3	AtmSelector	read-write	Specifies value to be used as Selector field component of LECS's ATM address.
T/F lecsValidateBestEffortPcr	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.4	TruthValue	read-write	When false, Best Effort Configuration Direct VCCs will be accepted without regard to the signalled forward Peak Cell Rate (PCR). When true, Best Effort VCCs will be rejected if the signalled forward PCR exceeds the line speed of the LECS ATM device. Calls will not be rejected due to the backward PCR. The signalled backward PCR will be honored if it does not exceed the line rate; otherwise, transmissions to the caller will be at line rate.
I32 configDirectMaxReservedBw	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.5	Integer32	read-write	Defines the maximum acceptable Sustained Cell Rate (SCR) for a Configuration Direct VCC; if SCR is not specified on the incoming call, then this parameter defines the maximum acceptable Peak Cell Rate (PCR) for a Configuration Direct VCC with reserved bandwidth. This parameter is applied to both forward and backward directions. Calls received with Traffic Parameters specifying higher rates will be released. If SCR is specified on the incoming call, the call will not be rejected due to the PCR or Maximum Burst Size. The constraint imposed by this parameter is not applicable to BEST EFFORT connections.
U32 atmDevLineSpeed	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.6	Unsigned32	read-only	Line Speed of LECS ATM Device. This should not exposed to the user.
U32 idleVccTime	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.7	Unsigned32	read-write	When the maximum number of VCCs is exceeded at the LECS, VCCs are released (see lecsMaxVccs). All active VCCs at the LECS are scanned. If a VCC has been inactive for this length of time, then it is released.
U32 lecsMaxVccs	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.8	Unsigned32	read-write	This is the maximum number of simultaneous VCCs supported by the LECS. If this number is exceeded, then VCCs will be released (see idleVccTime).
STR lecsDomainName	1.3.6.1.4.1.2.6.118.1.2.1.4.3.1.1.1.9	DisplayString	read-write	This is the name to associate with the Domain of the LECS
