What Is Nortel-Magellan-Passport-AtmIispMIB?

This MIB manages Interim Inter-Switch Signaling Protocol (IISP) configuration for ATM inter-switch signaling and routing on Nortel's Magellan Passport carrier switching platform. It belongs to the Nortel legacy ATM WAN switching technology area. It exposes provisioning and row-status tables for IISP components on ATM interfaces, including protocol version, side (network/user), and soft PVC retry timing parameters, following the Passport platform's characteristic component/row-status provisioning model. Its role is chiefly in configuring and verifying signaling interconnection status between ATM switches, confirming an IISP link's provisioned side and version match its peer and that soft PVC retries are not repeatedly failing, rather than exposing environmental hardware sensors. It builds on the general ATM UNI/NNI signaling model that IISP itself extends, and is structured according to Nortel Passport's common component-naming/row-status conventions shared across sibling Passport MIBs. It is typically deployed on Nortel Magellan Passport ATM switches at carrier network interconnection points. Engineers can download the Nortel-Magellan-Passport-AtmIispMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An operator would query atmIfIispProvTable/atmIfIispProvEntry for a given interface to check atmIfIispVersion and atmIfIispSide, confirming both ends of an inter-switch link agree on IISP version and network/user role, and would check atmIfIispRowStatusTable/atmIfIispRowStatus to verify the IISP component is provisioned active. Monitoring atmIfIispSoftPvcRetryPeriod alongside repeated retry attempts would reveal a soft PVC failing to establish across the IISP link, indicating a signaling mismatch or downstream connectivity problem. This table-and-row-status structure is typical of Passport component MIBs where status is inferred from row state rather than dedicated counters.

What Can Be Monitored

  • IISP link provisioning status
  • IISP protocol version
  • IISP side (network/user) configuration
  • soft PVC retry period
  • IISP component row status
