What Is Nortel-MsCarrier-MscPassport-Frf5EpMIB?

Nortel-MsCarrier-MscPassport-Frf5EpMIB provides SNMP objects for FRF.5 Frame Relay/ATM network interworking endpoints on Nortel MsCarrier MscPassport switches, the function that translates traffic between Frame Relay and ATM networks. It exposes RowStatus provisioning tables for interworking endpoint groups (mscMcsMgrFrf5EpG) as well as nested address tables (mscMcsMgrFrf5EpGAddr) associating network addresses with each endpoint. Its monitoring value lies in confirming that interworking endpoint components remain active and correctly addressed, since an inactive or misaddressed FRF.5 endpoint is a common software/configuration cause of traffic failing to cross between the Frame Relay and ATM sides of the network. It shares the RowStatus/component conventions of the MsCarrier MscPassport MIB suite and implements the Frame Relay Forum FRF.5 interworking specification. It is deployed on MscPassport switches that interconnect Frame Relay and ATM network segments. Engineers can download the Nortel-MsCarrier-MscPassport-Frf5EpMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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 MsCarrier Passport switch (Frame Relay/ATM interworking)

Monitoring Examples

An operator checks mscMcsMgrFrf5EpGRowStatusTable/mscMcsMgrFrf5EpGRowStatusEntry to confirm an FRF.5 interworking endpoint group is active, then examines mscMcsMgrFrf5EpGAddrRowStatusTable/mscMcsMgrFrf5EpGAddrRowStatusEntry to verify the associated network address entries are correctly provisioned. If traffic fails to interwork between the Frame Relay and ATM sides, a mismatched or inactive address entry in this table is a typical root cause to check first.

What Can Be Monitored

  • FRF.5 endpoint group row status
  • interworking address entries
  • provisioning parameters
  • storage type
