What Is Nortel-Magellan-Passport-AtmPnniMIB?

This Nortel Magellan Passport module manages PNNI (Private Network-to-Network Interface) ATM routing protocol configuration on Passport switches, covering topology, peer group membership, and reachability information used for dynamic ATM call routing. It exposes provisioning tables (atmIfVptPnniProvTable) and row-status tables (atmIfVptPnniRowStatusTable) for PNNI-enabled interfaces, along with signaling-related retry and hold-off timer settings for soft PVC/PVP connections. In monitoring terms it verifies PNNI protocol configuration health: confirming PNNI interfaces are correctly provisioned and active, and that soft PVC/PVP retry periods and hold-off timers are set appropriately to control how quickly failed soft connections are retried, which matters for network resilience during link failures. As a PNNI-specific module it depends on the ATM Forum's PNNI routing standard and sits alongside the sibling AtmBearerServiceMIB in the Passport MIB family, sharing row-status/component conventions. It was deployed on Nortel Magellan Passport ATM switches forming carrier-grade ATM backbone networks using dynamic PNNI routing, where Nortel-Magellan-Passport-AtmPnniMIB SNMP monitoring helped confirm PNNI interfaces stayed correctly provisioned and active.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-AtmPnniMIB. 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 troubleshooting slow reconvergence after an ATM link failure would check atmIfVptPnniSoftPvcRetryPeriod and atmIfVptPnniSoftPvpAndPvcHoldOffTime to confirm the configured retry/hold-off intervals for soft PVC/PVP re-establishment, and poll atmIfVptPnniProvTable/atmIfVptPnniProvEntry to verify PNNI interface provisioning is correct. A row in atmIfVptPnniRowStatusTable stuck outside the active state would indicate the PNNI interface failed to come up, disrupting topology advertisement to peer nodes.

What Can Be Monitored

  • PNNI interface provisioning/status
  • soft PVC/PVP retry period
  • soft PVC/PVP hold-off time
  • row status of PNNI-enabled interfaces
