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-ModAtmQosMIB?

Nortel-MsCarrier-MscPassport-ModAtmQosMIB is a Nortel (MsCarrier/Passport) vendor MIB for managing ATM Quality-of-Service parameters on module-level ATM network interfaces of Nortel Passport (Magellan Passport) multiservice switches. It exposes configuration objects for ATM/Frame-Relay-to-ATM network interworking components, including row-status-controlled provisioning tables for network components, retry timer settings, and traffic-parameter management (TPM) tables tied to specific ATM network interfaces. It supports monitoring of the software/configuration status of ATM QoS provisioning -- specifically whether network component and TPM row entries are active, provisioned, or in a failed row-status state -- which operators use to verify ATM QoS parameters have been correctly applied to a given module interface. As part of Nortel's large MsCarrier MscPassport enterprise MIB family, it depends heavily on companion Passport MIBs, such as base module, ATM interface, and Frame Relay MIBs, for full interface and component context. It was deployed on Nortel Passport carrier-class multiservice switches in service-provider networks offering ATM and Frame-Relay-to-ATM interworking services with defined QoS guarantees. Network engineers evaluating or troubleshooting this functionality can download the Nortel-MsCarrier-MscPassport-ModAtmQosMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An operator would check mscModFrsAtmNetRowStatusTable (mscModFrsAtmNetRowStatus, mscModFrsAtmNetComponentName) to confirm an ATM network interworking component is in the active row state on a given module, and review mscModFrsAtmNetProvTable (mscModFrsAtmNetRetryTimerPeriod) to verify provisioning retry timing is set correctly. A component stuck in a notReady or createAndWait row status in mscModFrsAtmNetTpmRowStatusTable would indicate an ATM QoS/TPM provisioning failure needing operator intervention.

What Can Be Monitored

ATM network component row/provisioning status
Frame-Relay-to-ATM interworking configuration
