Description: Provides DMTF standard management objects for mobile computing hardware components and power management.

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 DMTF-MOBILE-MIB?

DMTF-MOBILE-MIB is likewise a translation of a DMTF MIF file, here the Mobile Computer MIF, into SNMP objects via a DMI-to-SNMP mapping agent, making it a vendor-neutral standards-based module for laptop/mobile-computing hardware rather than a specific vendor's product. It exposes hardware bay inventory (dmtfDeviceBayTable, listing bay type, location, supported device types, and the device currently attached) and dynamic power-related states such as aCLineStatus. For monitoring purposes it is explicitly aimed at hardware status: whether AC power is connected versus running on battery, and what device is physically inserted in a given expansion/device bay (e.g., a second battery, optical drive, or hard disk bay), giving visibility into the physical configuration and power state of a mobile system. It relies on an underlying DMI-to-SNMP mapping agent and the broader DMTF DMI instrumentation framework to supply the data these objects surface. It would be deployed in IT-managed fleets of DMI-instrumented laptops/notebooks where administrators need remote visibility into battery/AC state and bay hardware without physically inspecting each machine. Engineers implementing or auditing this functionality typically reference the DMTF-MOBILE-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in DMTF-MOBILE-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

mobile computer / laptop (DMI-instrumented)
vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

Polling dmtfDeviceBayTable/dmtfDeviceBayEntry (indexed by deviceBayIndex) lets an admin check deviceBayType, deviceBayLocation, devicesSupported, and deviceCurrentlyAttached to confirm whether an expected device is still installed in a given bay. Separately, polling aCLineStatus from dmtfDynamicStatesTable reveals whether the laptop is currently on AC power or running on battery, useful for detecting an unplugged unit in the field or a failed docking connection. A bay reporting no device attached when one is expected, or an unexpected AC-to-battery transition, flags a hardware or power issue.

What Can Be Monitored

AC line/power status
device bay type and location
device currently attached in each bay
supported device types per bay
