What Is Nortel-MsCarrier-MscPassport-LaneClientMIB?

This Nortel MIB is part of the MscPassport family for the Nortel Passport WAN/ATM switching platform and covers ATM LAN Emulation (LANE) client configuration and status, letting an ATM network emulate a traditional LAN over an ATM backbone. It exposes objects for LEC (LAN Emulation Client) instance provisioning, customer identifier association, and mapping of LEC instances to logical interfaces, along with LE-ARP table data used to resolve MAC addresses to ATM addresses. Its role in monitoring device health centers on software/service status: administrators check whether LEC components are correctly provisioned and operational, whether customer ID associations are correct, and whether LE-ARP resolution is functioning, since a broken LEC prevents LAN emulation traffic from crossing the ATM fabric. It relies on the common MscPassport component-object conventions (row status, storage type, indexing) shared with the rest of the Passport MIB suite, and conceptually parallels the IETF LAN Emulation client MIB model. It is used in carrier or enterprise ATM backbone deployments where legacy LAN traffic is emulated over an ATM Nortel Passport switch. Engineers can download the Nortel-MsCarrier-MscPassport-LaneClientMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-LaneClientMIB. 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

  • Nortel Passport ATM WAN switch (LAN Emulation client)

Monitoring Examples

An operator checks mscLecRowStatusTable for a given mscLecIndex to confirm a LEC instance's mscLecRowStatus is active, then cross-references mscLecCidDataTable's mscLecCustomerIdentifier to ensure the LEC is tied to the correct customer. The mscLecIfEntryTable maps the LEC to its underlying interface, and issues with address resolution would show up in the mscLecLeArp table, where missing or stale entries indicate LE-ARP failures preventing MAC-to-ATM address mapping. Persistent LE-ARP misses combined with an active row status typically point to a LANE server or BUS reachability problem rather than local misconfiguration.

What Can Be Monitored

  • LEC row status
  • customer identifier association
  • LEC-to-interface mapping
  • LE-ARP address resolution entries
