Description: Supplies SNMP objects for configuring and reporting statistics on trunk 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-TrunksMIB?

Nortel-Magellan-Passport-TrunksMIB is a Nortel module for the Magellan Passport multiservice WAN switch, covering configuration and status of trunk interfaces used to interconnect Passport nodes over ATM/Frame Relay/leased-line facilities. It exposes trunk provisioning and row-status data, per-trunk administrative status, component naming/storage-type information, and trunk performance statistics. Its monitoring role is centered on hardware/software status of the trunk-level WAN links — whether a trunk is provisioned and active, administratively up or down, and how it is performing — which is essential for spotting a failed or misconfigured trunk between switch nodes. It follows the SNMPv2 conceptual row/RowStatus conventions for trunk provisioning, consistent with standard SMI table-management practice. Engineers working with legacy Passport equipment often open this module in a Nortel-Magellan-Passport-TrunksMIB MIB Browser to review the trunk tables before it is deployed in carrier and large-enterprise backbone networks running legacy Nortel Magellan Passport multiservice switching equipment.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-TrunksMIB. 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 multiservice ATM/Frame Relay WAN switch

Monitoring Examples

An admin would poll trkIfEntryTable, keyed by trkIfIndex, to check trkIfAdminStatus and confirm a trunk is administratively up, and check trkRowStatusTable/trkRowStatus to see whether a trunk row is active or still in provisioning. Persistently poor values in trkPorsStats for a given trkComponentName would reveal a congested or error-prone trunk between Passport nodes, pointing to a physical-layer or capacity problem.

What Can Be Monitored

  • trunk administrative status
  • trunk row/provisioning status
  • trunk component identification
  • trunk performance statistics
