Description: Network Peripherals Inc. (NPI) MIB for the DS24 NuSwitch, managing Ethernet switching chassis hardware including cards, ports, and MAC address tables

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-NuSwitch-COMMON-MIB?

This MIB module belongs to Network Peripherals Inc. (NPI), a legacy Ethernet networking vendor, and defines the enterprise SNMP tree used to manage the DS24 NuSwitch chassis-based Ethernet switching platform. It exposes categories of data related to chassis hardware inventory, card/module presence, port-level status, and Ethernet MAC address table entries used for switching decisions. Administrators rely on it to monitor hardware health of the switch chassis, including card insertion/removal status, port up/down state, and general device identity/uptime rather than deep software process detail. As a vendor enterprise MIB it sits under the standard SNMPv2-SMI enterprises subtree and depends on base SNMP framework conventions (mgmt, private, enterprises) rather than richer IETF interface or bridge MIBs. It is typically deployed in legacy enterprise wiring-closet or campus networks that still operate NPI DS24 NuSwitch hardware for basic Ethernet switching, and a Npi-NuSwitch-COMMON-MIB download is typically the starting point for loading the module into a MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Npi-NuSwitch-COMMON-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.

NPI DS24 NuSwitch Ethernet switch chassis

Monitoring Examples

An administrator would poll the NPI enterprise subtree under the npi node to confirm the DS24 NuSwitch chassis is reachable and to enumerate installed switching cards and their port counts. Because the available sample objects are limited to the standard tree roots (mgmt, directory, experimental, private, enterprises, npi), granular polling occurs against chassis- and port-level tables defined further down the npi branch, such as card and MAC-address-table entries specific to the NuSwitch. A sudden loss of response from the npi enterprise branch, or a card disappearing from the inventory table, would indicate a card failure or reseat is needed. This MIB is mostly used as the root registration point from which NuSwitch-specific hardware tables extend.
