Description: Provides SNMP management objects for OAM functions on Ethernet interfaces of Nortel Magellan Passport 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 Nortel-Magellan-Passport-OamEthernetMIB?

Nortel-Magellan-Passport-OamEthernetMIB provides SNMP objects for Operations, Administration, and Maintenance (OAM) functions on Ethernet interfaces of Nortel Magellan Passport switches, managed through a link-processor OAM Ethernet (lpOamEnet) component. It exposes row status/provisioning data for the OAM component, a customer-identifier data table mapping circuits to customer IDs, an interface-entry table that links the component to the standard ifTable, and a test sub-component for loopback/diagnostic operations. This allows an operator to monitor the operational state of Ethernet OAM instances, confirm which customer a given Ethernet circuit belongs to, and check test/diagnostic results, which together serve as fault-detection and service-assurance monitoring for the Ethernet hardware ports. It builds on the standard IF-MIB interface model (via lpOamEnetIfEntryTable) in addition to the Passport RowStatus/StorageType conventions. It is used on Nortel Magellan Passport switches carrying Ethernet-based services in carrier and enterprise WAN edge deployments. Engineers can download the Nortel-Magellan-Passport-OamEthernetMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-OamEthernetMIB. 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 Magellan Passport switch (Ethernet-equipped)

Monitoring Examples

An operator polls lpOamEnetRowStatusTable to confirm an Ethernet OAM component is active, then checks lpOamEnetCidDataTable for the lpOamEnetCustomerIdentifier associated with a given circuit to verify correct customer-to-port mapping. Cross-referencing lpOamEnetIfEntryTable ties the OAM component to its underlying ifTable interface for correlation with standard interface counters. Running or reviewing results from the lpOamEnetTest sub-component reveals whether an Ethernet OAM loopback/diagnostic test on that port passed or failed.

What Can Be Monitored

  • Ethernet OAM component status
  • customer identifier per circuit
  • linked interface status
  • OAM test/diagnostic results
