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-FraDpnTrunksMIB?

The Nortel-Magellan-Passport-FraDpnTrunksMIB is a Nortel private module for the Magellan Passport family of multiservice WAN switches, covering Frame Relay access carried over DPN (Datapac Network) trunk connections. It exposes provisioning and row-status tables for Frame Relay access components — including component naming, storage type, error-interval thresholds, and receive-error sensitivity — along with a state table reflecting the current operational condition of each Frame Relay/DPN trunk access. Its monitoring value centers on software/configuration state and fault detection at the trunk level: administrators use the state and provisioning tables to confirm a Frame Relay access component is correctly provisioned and to detect when error thresholds have been exceeded, signaling trunk-line degradation. As a DPN/Frame Relay module within the broader Magellan Passport MIB suite, it depends on and complements other Passport MIB modules covering the underlying trunk/physical layer and general component/row-status conventions. It was deployed on legacy Nortel Magellan Passport WAN switches used by carriers and large enterprises for Frame Relay and X.25/DPN packet-switched services, and engineers today can download the Nortel-Magellan-Passport-FraDpnTrunksMIB file to reference its object definitions when maintaining legacy equipment.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-FraDpnTrunksMIB. 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 WAN switches

Monitoring Examples

An administrator would use dpnGateFrAccessRowStatusTable/dpnGateFrAccessRowStatusEntry (indexed by dpnGateFrAccessIndex) to confirm a Frame Relay access component's dpnGateFrAccessRowStatus is active, and check dpnGateFrAccessProvTable for dpnGateFrAccessMaximumErroredInterval and dpnGateFrAccessReceiveErrorSensitivity settings governing fault thresholds. Monitoring dpnGateFrAccessStateTable would reveal whether a given Frame Relay access has transitioned to a degraded or failed state, indicating a problem on the underlying DPN trunk. This lets carrier operations staff isolate whether a Frame Relay service disruption originates at the access/provisioning layer.

What Can Be Monitored

  • Frame Relay access row/provisioning status
  • error-interval thresholds
  • receive-error sensitivity
  • Frame Relay/DPN trunk access state
