VPIEVENT-MIB

Description: Defines SNMP event notifications for VPI virtual path interface alarms and state changes.

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.

VPIEVENT-MIB is a vendor-specific SNMP module defining event notifications (traps) for ATM Virtual Path Interface (VPI) alarms and state transitions, rather than a general management MIB with polled data tables. It falls squarely in the faults/traps category: it defines notification types and varbinds sent when a VPI interface changes state (e.g., up/down) or raises an alarm condition. Because it is a notification-defining module, its monitoring use is largely passive -- a management station subscribes to receive these traps rather than polling counters -- though the traps themselves are the primary mechanism for detecting hardware-level VPI/ATM interface faults such as link failure or alarm indication signals. It is dependent on the underlying ATM/VPI interface MIB (a companion module defining the VPI interface table) whose objects it references in trap varbinds. It would be deployed on ATM switching/access equipment where VPI-level fault notification is needed for real-time alarm monitoring, making this VPIEVENT-MIB reference useful for correlating trap-based ATM path faults.

Only the module's import clause was present in the extracted source, with no concrete object or table names available, so no specific object-polling scenario can be given; based on the short description, this module defines trap notifications sent when a VPI interface changes state or raises an alarm, which a management station would receive and correlate to detect ATM path-layer hardware faults rather than poll for directly.

Event management MIB used for monitoring and reporting events in network management systems, potentially related to Viavi Solutions monitoring tools. Provides trap definitions for event notification handling.
