What Is Nortel-MsCarrier-MscPassport-DpnTrunksMIB?

This module belongs to the Nortel MsCarrier MscPassport family and defines management objects for DPN (Datapac Network / Nortel's legacy X.25-based packet network) trunk interfaces on the Passport switching platform. It exposes row-status/provisioning tables for DPN gateway trunk components, interface-level admin status, and forwarding statistics for the trunk. As a monitoring tool it supports both configuration-state checks (row status, admin status) and basic performance/forwarding statistics tracking for DPN trunks, letting an operator confirm a trunk interface is administratively up and forwarding traffic as expected versus being disabled or faulted. It shares the same MsCarrier component-object conventions used across sibling MscPassport MIBs (e.g., PORS and Frame Relay UNI trunk MIBs), indicating a common architectural dependency. It is deployed on legacy Nortel Passport/MscPassport carrier switches used by telecom operators for X.25/DPN packet-trunk interconnection. Engineers can download the Nortel-MsCarrier-MscPassport-DpnTrunksMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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 MsCarrier MscPassport WAN switch

Monitoring Examples

An operator checks mscDpnGateRowStatusTable/mscDpnGateRowStatusEntry for mscDpnGateRowStatus and mscDpnGateComponentName to confirm a DPN trunk component is active, then reviews mscDpnGateIfEntryTable's mscDpnGateIfAdminStatus to verify the trunk interface is administratively enabled. The mscDpnGateFwdStats group would be consulted for forwarding statistics to confirm the trunk is actively passing traffic rather than sitting idle due to a misconfiguration.

What Can Be Monitored

  • DPN trunk component row status
  • trunk interface admin status
  • trunk forwarding statistics
  • trunk provisioning parameters
