What Is Nortel-Magellan-Passport-AtmUniMIB?

Nortel-Magellan-Passport-AtmUniMIB is a Nortel Magellan Passport switch MIB governing ATM User-Network Interface (UNI) signaling, address registration, and connection admission on this multiservice WAN switching platform. It exposes tables for UNI interface provisioning and status, including UNI version, side (user/network), soft PVC retry behavior, and an ILMI (Interim Local Management Interface) sub-branch used for UNI address/parameter negotiation. Its monitoring focus is on the operational and configuration status of ATM UNI links: verifying atmIfUniRowStatus shows an interface is active, confirming atmIfUniVersion and atmIfUniSide match the expected signaling configuration, and watching soft-PVC retry activity as an indicator of connection setup problems on the interface. Like its sibling AtmTrunksMIB, it follows the Passport platform's common RowStatus/StorageType/ComponentName conventions for provisioned objects. It is deployed on Nortel Magellan Passport nodes providing ATM UNI access for carrier or enterprise ATM services. Engineers can download the Nortel-Magellan-Passport-AtmUniMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-AtmUniMIB. 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 check atmIfUniRowStatusTable/atmIfUniRowStatusEntry's atmIfUniRowStatus per atmIfUniIndex to confirm a UNI interface is provisioned and active rather than stuck in a notReady state. Reviewing atmIfUniProvTable/atmIfUniProvEntry fields such as atmIfUniVersion, atmIfUniSide, and atmIfUniSoftPvcRetryPeriod helps diagnose why a soft PVC on that interface repeatedly fails to establish, since a mismatched UNI version or side setting is a common misconfiguration. The atmIfUniIlmi branch would be consulted to check ILMI-based address registration status for the interface.

What Can Be Monitored

  • ATM UNI interface row/operational status
  • UNI version and side
  • soft PVC retry period
  • ILMI registration status
