Description: Enterprise MIB for NPI intelligent network devices covering device identification, monitoring, and actions, originally adapted for the XACT DS24+ managed Ethernet switch

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.

What Is NPI-DEV-MIB?

NPI-DEV-MIB is a generic enterprise MIB (registered under enterprises.1101, 'npi') originally created for NPI's own line of 'intelligent network devices' and, per the file's header, subsequently modified by XACT Inc. for the NuWave DS24+ 24-port 10/100 managed Ethernet switch — the description text for devDeviceName explicitly gives that product as its example value, indicating NPI here is a networking-equipment vendor rather than a printer manufacturer, contrary to the 'National Printers Inc.' label supplied alongside this MIB. It defines device identification objects (devDeviceName, devDeviceType — hub/bridge/switch/router, devDeviceModel, hardware/software/SNMP/MIB versions), a per-interface table (devDeviceIfTable: operational status, MAC/IP/subnet/gateway per interface), a vendor-specific-OID table advertising which enterprise MIB groups the device implements, a trap-manager table configuring where traps are sent, monitoring scalars for the most recent trap event (level, message, timestamp, port), and action objects (devActReset, devActFactoryReset, devActTest) for remote device control. This is useful for monitoring basic device identity, interface addressing, and the most recent trap/alarm condition on NPI-derived switches, and for triggering resets or self-tests remotely. It is deployed on XACT NuWave DS24+ managed Ethernet switches and other NPI common-MIB-based intelligent devices. Administrators managing this equipment can reference the NPI-DEV-MIB MIB when building device inventory and alerting.

IPNetwork Monitor allows you to monitor SNMP objects defined in NPI-DEV-MIB. 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

XACT NuWave DS24+ 24-port managed Ethernet switch (NPI common-MIB-based devices)

Monitoring Examples

An operator polls devMonTrapReportLevel and devMonTrapReportString after an alert fires, cross-referencing devMonTrapReportPortNumber to identify the affected interface, then checks devDeviceIfEntry for that port's operational status; an interface reporting devDeviceIfOperation as 'failure' alongside a matching high-severity trap message would confirm a hardware fault on that port rather than a transient link flap.

What Can Be Monitored

device type/model/hardware-software version identity
per-interface operational status and IP/MAC addressing
supported vendor-specific MIB groups
trap manager destination configuration
most recent trap event level/message/timestamp/port
remote reset/factory-reset/self-test action results
