Description: Covers management of the ATM LANE Emulation Server (LES) and Broadcast/Unknown Server (BUS) on Nortel Centillion switches.

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 CENTILLION-LESBUS-MIB?

CENTILLION-LESBUS-MIB manages the ATM LAN Emulation Server (LES) and Broadcast/Unknown Server (BUS) functions on Nortel Centillion switches, which are core components of classical LAN emulation (LANE) over ATM. It exposes objects describing configured LES/BUS instances, their server IDs and ATM addresses, and peer relationships between LES/BUS servers in a LANE fabric. This is primarily configuration and connectivity-state monitoring: administrators use it to verify that a LES/BUS server is correctly bound to its expected ATM address and that peer server relationships are established, which is essential to diagnosing LANE clients that cannot join an emulated LAN. It depends conceptually on the ATM Forum LANE specification and works alongside other Centillion MIBs such as CENTILLION-VLAN-MIB and CENTILLION-ATMMON-MIB. It is deployed in legacy Nortel Centillion ATM switch fabrics providing LAN emulation services to bridge Ethernet/Token Ring traffic over ATM backbones. Network engineers evaluating or troubleshooting this functionality can download the CENTILLION-LESBUS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CENTILLION-LESBUS-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 operator would query cnLesBusTable/cnLesBusEntry, keyed by cnLesBusConfIndex, to check cnLesBusBusAddrActual against cnLesBusBusAddrSpec and confirm the BUS server is bound to its configured ATM address. cnLesBusPeerTable, keyed by cnLesBusIndex and cnLesBusPeerIndex, would be checked to verify expected LES/BUS peer relationships are present, since a missing peer entry typically explains why LANE clients on a remote switch cannot reach the emulated LAN. cnLesBusSmartLes indicates whether the 'smart LES' optimization is enabled for that server instance.
