What Is Nortel-Magellan-Passport-DpnTrunksMIB?

This Nortel Magellan Passport module manages DPN (Distributed Packet Network) trunk interfaces on Passport platforms, covering trunk ('gate') configuration, interface administrative status, and forwarding traffic statistics for legacy DPN packet-switched trunks. It exposes provisioning and row-status tables (dpnGateRowStatusTable, dpnGateProvTable), an interface status table (dpnGateIfEntryTable) tracking dpnGateIfAdminStatus per dpnGateIfIndex, and forwarding statistics (dpnGateFwdStats). Its monitoring purpose spans both configuration and operational/traffic status: confirming a DPN trunk's row is active and its administrative status is up, while forwarding statistics reveal actual traffic throughput or errors on the trunk, useful for detecting congestion or a failed/degraded trunk link. It shares the common Passport component/row-status conventions with sibling modules like DpnRoutingMIB, reflecting the same underlying Passport packet-network architecture. It was deployed on Nortel Magellan Passport switches carrying legacy DPN/X.25 trunk traffic in carrier packet-switched networks, where Nortel-Magellan-Passport-DpnTrunksMIB SNMP monitoring tracked trunk administrative status and forwarding statistics.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-DpnTrunksMIB. 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 DPN packet switch

Monitoring Examples

An operator would poll dpnGateIfEntryTable (dpnGateIfEntryEntry, keyed by dpnGateIfIndex) to check dpnGateIfAdminStatus and confirm a DPN trunk is administratively up, then examine dpnGateFwdStats to see forwarding traffic volumes or error counts on that trunk. A trunk showing adminStatus up but with dpnGateRowStatusTable reporting a non-active provisioning row, or with forwarding stats showing a sudden drop, would indicate a failed or misconfigured trunk needing investigation.

What Can Be Monitored

  • DPN trunk (gate) row/provisioning status
  • trunk interface admin status
  • trunk forwarding statistics
