What Is Nortel-Magellan-Passport-AtmBearerServiceMIB?

This is one of a family of Nortel Magellan Passport MIB modules, covering ATM bearer service configuration on Passport wide-area switching platforms, specifically Network Resource Partitioning (NRP) for ATM virtual path connections (VPCs) and virtual channel connections (VCCs) supporting CBR, VBR, and UBR service categories. It exposes provisioning tables (atmIfVpcNrpProvTable) and row-status/component management tables (atmIfVpcNrpRowStatusTable) that define how ATM bandwidth resources are partitioned and provisioned per interface. Its role in monitoring is configuration/provisioning verification rather than hardware fault detection: administrators confirm NRP connection point types, next-hop routing, and OAM segment boundary settings are correctly provisioned for a given ATM VPC, and check row status to ensure entries are active. Given its Magellan Passport lineage this module is part of a broader Nortel Passport MIB suite and shares common component-naming/row-status conventions (atmIfVpcNrpComponentName, atmIfVpcNrpStorageType) with sibling Passport MIBs. It was deployed on Nortel Magellan Passport ATM/frame-relay wide-area switches in carrier and enterprise WAN backbone networks, and engineers supporting these platforms can obtain a Nortel-Magellan-Passport-AtmBearerServiceMIB download to load the module into their provisioning tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-AtmBearerServiceMIB. 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 ATM/WAN switch

Monitoring Examples

An administrator would poll atmIfVpcNrpProvTable (rows in atmIfVpcNrpProvEntry) to verify the atmIfVpcNrpNextHop and atmIfVpcNrpConnectionPointType provisioned for a given VPC, and check atmIfVpcNrpOamSegmentBoundary to confirm OAM cell handling boundaries are set correctly for fault isolation. Checking atmIfVpcNrpRowStatusTable entries for a row stuck in a non-active state would reveal a failed or incomplete provisioning operation on that ATM interface.

What Can Be Monitored

  • ATM VPC/VCC NRP provisioning
  • connection point type
  • next-hop configuration
  • OAM segment boundary settings
  • row/provisioning status
