ATM-SOFT-PVC-TRAP-MIB is a vendor MIB defining SNMP trap notifications for ATM Soft PVC (Permanent Virtual Circuit) state changes, covering events such as circuit setup failure and teardown. As a traps-only module, it doesn't expose ongoing performance counters but instead reports discrete state-change events for ATM soft PVCs, dynamically signaled virtual circuits that emulate static PVCs. It is used to monitor the software/protocol status of ATM virtual circuit provisioning, alerting an admin the moment a soft PVC fails to establish or is torn down unexpectedly, which is critical since ATM soft PVCs often carry latency-sensitive traffic. It depends on the standard ATM-MIB (RFC 2515) for VCL/VPL indexing conventions that the traps reference. It is typically deployed on ATM switches and edge routers in legacy carrier or enterprise ATM networks requiring real-time fault notification for virtual circuit failures. Engineers can download the ATM-SOFT-PVC-TRAP-MIB file directly to load it into their MIB browser.

No specific object or trap names were provided for this module, so a precise polling example cannot be constructed with grounded identifiers. In general, an NMS receiving this MIB's traps would be alerted the moment a soft PVC setup-failure or teardown event occurs on a given VCL/VPL, prompting an admin to check the affected ATM interface and virtual circuit endpoint for a signaling or connectivity fault. Repeated setup-failure traps for the same circuit would point to a persistent signaling or provisioning mismatch between endpoints.

SNMP MIB module for managing and monitoring Soft Permanent Virtual Circuits (Soft-PVC) on ATM networks. Defines trap definitions and management objects for Soft-PVC call failures, rerouting, and interface status.
