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-MsCarrier-MscPassport-AtmUniMIB?

Nortel-MsCarrier-MscPassport-AtmUniMIB is a Nortel Networks enterprise MIB for the MSCarrier/Passport (formerly Magellan Passport) multiservice switching platform, providing management of ATM UNI (User-Network Interface) signaling. It exposes both provisioning/configuration objects — such as UNI version, side (user/network), and soft-PVC retry period — and row-status-controlled tables used to create and manage UNI interface instances, along with ILMI-related structures. Its monitoring value is primarily configuration and protocol status: administrators use it to confirm an ATM UNI interface is correctly provisioned, verify its signaling version and side role, and track soft-PVC retry behavior which indicates connection setup problems on the ATM interface. As an ATM UNI MIB it operates within the broader family of ATM Forum/ITU-T UNI signaling conventions, though it is a self-contained Nortel proprietary implementation. It is deployed on legacy Nortel MSCarrier Passport switches used in carrier ATM/broadband networks. Engineers can download the Nortel-MsCarrier-MscPassport-AtmUniMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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 MSCarrier Passport (Magellan Passport) ATM switch

Monitoring Examples

An operator would use mscAtmIfUniRowStatusTable/mscAtmIfUniRowStatusEntry to confirm a UNI interface's mscAtmIfUniRowStatus is active, then check mscAtmIfUniProvTable for mscAtmIfUniVersion and mscAtmIfUniSide to verify the interface is provisioned with the correct UNI signaling version and role. mscAtmIfUniSoftPvcRetryPeriod would be inspected when troubleshooting a soft PVC that repeatedly fails to establish, to confirm the retry timing matches expectations, while mscAtmIfUniIlmi indicates whether ILMI auto-configuration is active on that interface.

What Can Be Monitored

  • UNI interface row status
  • UNI signaling version
  • UNI side (user/network)
  • soft PVC retry period
  • ILMI configuration status
