Description: Manages network stack configuration and protocol layer statistics on devices using the NSTACK software framework.

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 NSTACK-MIB?

NSTACK-MIB is a vendor MIB (module description not provided) that manages network protocol stack configuration and per-layer statistics for devices built on an "NSTACK" software networking framework, based on its base object naming (nbase, nbSwitchG1). It appears to expose switch-group configuration and stack information objects, suggesting categories of data around switching group membership and protocol-layer counters rather than classic hardware sensors. Given the limited object list, its monitoring value likely centers on software-stack/protocol status such as switch-group operational state and stack information rather than temperature or power; this should be treated as tentative given the sparse detail available. No explicit dependency on other MIBs is stated in the available material. It would typically be deployed on switch or networking-appliance devices running this vendor's NSTACK-based network software. Engineers can download the NSTACK-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NSTACK-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

networking switch/appliance running NSTACK software

Monitoring Examples

An administrator would read nbSwitchG1 and its child nbSwitchG1Il alongside nbsStackInfo to check switch-group configuration and stacking status, watching for unexpected changes in stack membership or group state that could indicate a software-stack fault. Because only a handful of top-level object names are available, more specific table/counter-level detail cannot be honestly inferred.
