Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. 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-Magellan-Passport-IpiFrMIB?

This MIB module belongs to the Nortel Magellan Passport product family and manages the IP Interworking (IPI) function over Frame Relay interfaces on the Magellan Passport WAN switch. It exposes provisioning data such as IP address and subnet mask assignment, the maximum number of logical channel numbers (LCNs), and standard row-status/component-identity objects for each IPI-over-FR interface instance. Network engineers use it to monitor whether an IP-over-Frame-Relay interworking interface is correctly configured and operationally active, since an incorrect ipiFrIpAddress/ipiFrSubnetMask or a non-active ipiFrRowStatus directly affects the interface's ability to carry IP traffic, making this effectively a software configuration health check on the switch. It shares the common Passport component/row-status framework (ipiFrComponentName, ipiFrStorageType) used across sibling MIBs in the suite. It is deployed on carrier-grade Magellan Passport nodes providing IP-over-Frame-Relay interworking services in legacy WAN networks. Network engineers evaluating or troubleshooting this functionality can download the Nortel-Magellan-Passport-IpiFrMIB file directly to load it into their MIB browser.

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

Monitoring Examples

Polling ipiFrProvTable/ipiFrProvEntry lets an operator read ipiFrIpAddress, ipiFrSubnetMask, and ipiFrMaximumNumberOfLcn for each IPI-FR interface, verifying the addressing matches the intended subnet plan. Checking ipiFrRowStatus confirms whether the interface instance identified by ipiFrIndex is active; a stuck notInService state would indicate the interworking link failed to come up. This is fundamentally a configuration/status view rather than a live traffic-counter table.

What Can Be Monitored

  • IPI-FR interface row status
  • assigned IP address
  • subnet mask
  • maximum number of LCNs
  • component storage type
