What Is Nortel-Magellan-Passport-Frf5EpMIB?

This Nortel Magellan Passport module manages FRF.5 (Frame Relay Forum Implementation Agreement 5) network interworking configuration on Passport platforms, which defines how Frame Relay traffic is carried over an ATM network via interworking endpoints. It exposes group-level row-status/provisioning tables (mcsMgrFrf5EpGRowStatusTable) and address-level row-status tables (mcsMgrFrf5EpGAddrRowStatusTable) that define FRF.5 endpoint groups and their associated addressing. Its monitoring value is configuration/provisioning verification for the interworking function: confirming FRF.5 endpoint groups and their address entries are correctly provisioned and in an active row status, necessary for Frame Relay-to-ATM interworking traffic to flow correctly between the two network types. This module explicitly implements the Frame Relay Forum's FRF.5 standard for network interworking, making that specification its key dependency, in addition to sharing the common Passport component/row-status conventions. It was deployed on Nortel Magellan Passport switches providing Frame Relay-to-ATM network interworking gateways in carrier multiservice networks. Engineers can download the Nortel-Magellan-Passport-Frf5EpMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-Frf5EpMIB. 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 Frame Relay/ATM interworking switch

Monitoring Examples

An operator would poll mcsMgrFrf5EpGRowStatusTable (mcsMgrFrf5EpGRowStatusEntry) to confirm a FRF.5 interworking endpoint group is provisioned and active, then check mcsMgrFrf5EpGAddrRowStatusTable/mcsMgrFrf5EpGAddrRowStatusEntry for the associated address entries to verify addressing is correctly mapped between the Frame Relay and ATM sides. A row stuck in a non-active state in either table would indicate a failed interworking configuration, likely causing traffic between the Frame Relay and ATM segments to fail.

What Can Be Monitored

  • FRF.5 endpoint group row/provisioning status
  • endpoint address entry status
  • interworking group configuration
