What Is Nortel-Magellan-Passport-AtmTrunksMIB?

Nortel-Magellan-Passport-AtmTrunksMIB is a Nortel Magellan Passport wide-area switch MIB for managing ATM trunk interfaces, covering trunk provisioning, bandwidth/error-rate configuration, and trunk group status on this carrier-grade multiservice switching platform. It exposes row-status-controlled tables for creating/deleting/modifying trunk components, along with provisioning attributes such as maximum errored interval and receive error sensitivity thresholds used for line-quality supervision. Its monitoring role centers on the fault and configuration status of ATM trunks: tracking trunkAtmRowStatus to see whether a trunk is active, testing, or out of service, and watching error-interval thresholds to detect a trunk experiencing excessive line errors that could indicate a physical link or framing problem. It follows the Passport platform's common component-model conventions (RowStatus, StorageType, ComponentName) shared across other Magellan Passport MIBs like the ATM UNI and call redirection modules. It is deployed on Nortel Magellan Passport switches used as ATM/frame relay/IP multiservice wide-area network nodes by carriers and large enterprises. Engineers can download the Nortel-Magellan-Passport-AtmTrunksMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An operator would walk trkAtmRowStatusTable/trkAtmRowStatusEntry, checking trkAtmRowStatus per trkAtmIndex to confirm each provisioned ATM trunk is in the active state rather than notInService or failed. Reviewing trkAtmProvTable/trkAtmProvEntry fields such as trkAtmMaximumErroredInterval and trkAtmReceiveErrorSensitivity against trkAtmAtmAccMaximumErroredInterval would reveal whether a trunk is approaching its configured error tolerance, an early indicator of a degrading physical link. trkAtmComponentName ties a given trunk's status back to its logical component name for correlation with other Passport component tables.

What Can Be Monitored

  • ATM trunk row/operational status
  • maximum errored interval
  • receive error sensitivity
  • trunk component name and storage type
