What Is Nortel-Magellan-Passport-IpiVcMIB?

Nortel-Magellan-Passport-IpiVcMIB is a Nortel enterprise MIB for the Magellan Passport wide-area switching platform, covering IP Interworking over Virtual Circuit (IPIVC) configuration and status. It exposes provisioning tables for IPIVC components, including row status, IP addressing, and the maximum number of logical channels (LCNs) permitted per interworking instance, along with a DNA (Dynamic Network Address?) row status table. This MIB is largely configuration-oriented but does allow monitoring of the operational row status of IPIVC components, which reveals whether an interworking circuit is active, provisioned, or in a failed state. It follows Nortel's common Passport component/row-status MIB pattern shared across other MsCarrier Passport MIBs. It was deployed on Nortel Magellan Passport WAN switches providing IP-over-ATM/Frame Relay interworking services in carrier networks. Network engineers evaluating or troubleshooting this functionality can download the Nortel-Magellan-Passport-IpiVcMIB file directly to load it into their MIB browser.

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

An administrator would poll ipivcRowStatusTable entries via ipivcRowStatus to confirm an IPIVC component is active, and check ipivcProvTable for the configured ipivcIpAddress and ipivcMaximumNumberOfLcn to ensure the circuit isn't hitting its logical channel limit. A row status stuck in a notReady or failed state would indicate a provisioning or hardware problem preventing the interworking circuit from passing traffic.

What Can Be Monitored

  • IPIVC component row status
  • IP address provisioning
  • maximum logical channel count
  • DNA row status
