What Is NSCDX-MIB?

NSCDX-MIB is a vendor MIB from Network Systems Corporation (NSC) for managing the DX series of network devices (channel extension/data communications equipment), covering system configuration, board inventory, and performance counters. It exposes objects for firmware revision tracking per board, memory/buffer sizing, processor allocation masks, time-since-last-reset, control addressing, and a per-slot board information table identifying installed hardware. This MIB directly supports hardware and software status monitoring: it tracks firmware revision per board, buffer memory size, elapsed time since last microcode/config change, and processor load distribution, giving operators visibility into both the software configuration and physical hardware inventory of a modular DX chassis. It appears to be a standalone enterprise MIB predating dependence on later IETF entity/hardware standards, functioning instead with its own board/slot addressing scheme. It is typically deployed in legacy NSC DX-series data communications equipment installations where administrators need to verify firmware consistency and hardware inventory across multiple slots. Engineers can download the NSCDX-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NSCDX-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.

What Can Be Monitored

per-board firmware revision
buffer memory size
time since last reset/microcode change
processor allocation mask
board/slot inventory (part numbers)

Supported Devices

Network Systems Corporation (NSC) DX-series data communications/channel extension equipment

Monitoring Examples

An administrator would poll nscDxConfigBoardInfoTable (via nscDxConfigBoardInfoEntry, keyed by nscDxConfigBoardInfoEntSlotNum) to inventory installed boards and their part numbers (nscDxConfigBoardInfoEntBoardPart), cross-checking against nscDxConfigFirmwareRevTab to confirm all boards run consistent firmware revisions. The nscDxConfigSecondsToReset and nscDxConfigSecondsSinceMc counters reveal how long since the device was last reset or underwent a microcode change, useful for correlating a recent instability report with a configuration event. Polling nscDxConfigBufferMemorySize and nscDxConfigProcessorMask lets an operator confirm the device has adequate buffering and processor resources for its current traffic load.
