Description: Manages device configuration parameters, startup settings, and operational mode for network devices.

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 DEV-CFG-MIB?

DEV-CFG-MIB is a proprietary device-configuration MIB (Nbase/NbaseSwitch lineage, judging by its object prefixes) that manages general operating parameters of a network device, including its operation mode, error reporting, router configuration save, temperature-monitoring mode, and power-supply inventory. It exposes a mix of configuration objects (nbDevOperationMode, nbDevRouterSaveConfig) and hardware-status objects, most notably a power-supply table (nbsDevPSTable) reporting the type, description, and redundancy mode of each installed power supply. This gives it clear hardware/environmental monitoring value: an administrator can confirm whether power-supply redundancy is correctly configured and whether the device's temperature-monitoring feature (nbsDevTemperatureMode) is active, both important for detecting a device at risk from power or thermal failure. It has no strong dependency on external standard MIBs, functioning as a self-contained vendor configuration/status model. It is deployed on the vendor's Layer 2/3 switches or routers in enterprise network closets or data centers. Network engineers evaluating or troubleshooting this functionality can download the DEV-CFG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DEV-CFG-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

Nbase-family Layer 2/3 switch or router

Monitoring Examples

An administrator would poll nbsDevPSTable entries - nbsDevPSType, nbsDevPSDescription, and nbsDevPSRedundantMode - to confirm each installed power supply is recognized and that redundant mode is enabled where expected. nbDevOperationMode and nbsDevTemperatureMode would be checked to confirm the device is running in its intended mode with temperature monitoring active. If nbDevErrorText reports a non-empty error string, that would flag a configuration or operational problem requiring investigation, and nbDevRouterSaveConfig would confirm whether pending configuration changes have been committed to persistent storage.

What Can Be Monitored

device error text/status
configuration save state
