What Is Nortel-Magellan-Passport-ModAtmQosMIB?

Nortel-Magellan-Passport-ModAtmQosMIB is a Nortel Magellan Passport (legacy multi-service WAN switch) MIB for module-level ATM quality-of-service configuration on Frame Relay-to-ATM network-interworking connections. It defines provisioning objects such as network-connection row status, retry timer periods, and traffic-parameter-mapping (TPM) tables for ATM QoS on individual switch modules/components. This is primarily a configuration/provisioning MIB for connection-oriented ATM QoS parameters rather than one exposing hardware sensors; monitorable aspects are largely limited to the administrative/row status of provisioned QoS entries and retry-timer settings, which if abnormal reveal provisioning failures or connection-setup problems. As a component of the broader Magellan Passport MIB family it depends on shared Passport module/component-naming conventions such as modFrsAtmNetComponentName and modFrsAtmNetIndex. It was deployed on Nortel Magellan Passport multi-service WAN switches used by carriers for Frame Relay/ATM interworking, a now-legacy technology, and engineers researching it today can download the Nortel-Magellan-Passport-ModAtmQosMIB file for reference in a MIB browser.

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

modFrsAtmNetProvTable/modFrsAtmNetProvEntry exposes modFrsAtmNetRetryTimerPeriod, the retry interval used when establishing an ATM network connection - an unusually high retry rate against a long timer period could indicate a failing ATM link. modFrsAtmNetRowStatusTable's modFrsAtmNetRowStatus and modFrsAtmNetStorageType let an admin confirm whether a given QoS provisioning entry is active, notInService, or otherwise not properly committed. modFrsAtmNetTpmRowStatusTable tracks traffic-parameter-mapping entries per component (modFrsAtmNetComponentName, modFrsAtmNetIndex), which an operator would check to verify QoS mappings are correctly applied to a specific module.

What Can Be Monitored

ATM network connection row status
retry timer period
traffic parameter mapping status
component/module index provisioning state
