What Is Nortel-MsCarrier-MscPassport-FraDpnTrunksMIB?

This Nortel MsCarrier MscPassport MIB manages Frame Relay Adaptation (FRA) DPN trunk interfaces, providing SNMP objects for the "gateway" access components that adapt legacy DPN (Datapac-style) network trunks into Frame Relay services on the Passport switch. It exposes provisioning tables including access error-sensitivity thresholds (maximum errored interval, receive error sensitivity), Frame Relay multiplexing setup parameters, and a state table for tracking access-component operational status. This makes the MIB useful for monitoring link-quality/fault thresholds -- specifically how many errors within an interval are tolerated before the access component is declared faulty -- functioning as a software-level health indicator for the trunk's link integrity. It relies on Nortel's proprietary DPN/Frame Relay gateway architecture layered on the shared Passport component-provisioning model. It is deployed where legacy DPN packet-switched trunks are being migrated to or interworked with Frame Relay over a Nortel Passport backbone. Engineers can download the Nortel-MsCarrier-MscPassport-FraDpnTrunksMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An engineer would check mscDpnGateFrAccessProvTable/mscDpnGateFrAccessProvEntry for the configured mscDpnGateFrAccessMaximumErroredInterval and mscDpnGateFrAccessReceiveErrorSensitivity, then poll mscDpnGateFrAccessStateTable to see whether the access component's operational state reflects a fault due to exceeding that error threshold. A repeatedly faulted state combined with a low error-sensitivity setting suggests the trunk's underlying physical link is degraded. mscDpnGateFrAccessFrMuxSetup entries would be reviewed to confirm the Frame Relay multiplexing configuration matches the far-end DPN gateway.

What Can Be Monitored

  • access component operational state
  • maximum errored interval threshold
  • receive error sensitivity
  • Frame Relay multiplex setup
