Description: Reports temperature sensor readings and threshold alarms on Aruba CX switch hardware.

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 ARUBAWIRED-TEMPSENSOR-MIB?

ARUBAWIRED-TEMPSENSOR-MIB is an Aruba Networks (HPE) MIB for Aruba CX series wired switch hardware, dedicated to temperature sensor reporting. It exposes a temperature sensor table keyed by group/slot-type/slot/sensor index, giving current temperature reading, sensor state, and configured minimum/maximum thresholds, with associated notifications. This is purely a hardware environmental-health MIB -- its entire purpose is exposing temperature readings and sensor state so operators can catch an overheating chassis, line card, or module before it triggers a thermal shutdown or hardware fault. It is a self-contained hardware MIB but ties into Aruba's broader chassis/slot indexing scheme shared across other ArubaWired hardware MIBs, and it defines its own notifications for threshold events. It is deployed on Aruba CX series switches in enterprise wired network infrastructure for real-time environmental/thermal monitoring. Engineers can download the ARUBAWIRED-TEMPSENSOR-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

An administrator would poll arubaWiredTempSensorTable/arubaWiredTempSensorEntry, indexed by arubaWiredTempSensorGroupIndex, arubaWiredTempSensorSlotTypeIndex, arubaWiredTempSensorSlotIndex, and arubaWiredTempSensorIndex, reading arubaWiredTempSensorTemperature against arubaWiredTempSensorMinTemp/arubaWiredTempSensorMaxTemp for each named sensor (arubaWiredTempSensorName). A sensor whose arubaWiredTempSensorState turns non-normal while its temperature approaches arubaWiredTempSensorMaxTemp indicates a specific slot or module is overheating, and arubaWiredTempSensorNotifications would alert on that threshold crossing.

What Can Be Monitored

per-sensor temperature reading
sensor operational state
minimum/maximum temperature thresholds
sensor location (group/slot/index)
temperature threshold notifications

How to Use in IPNetwork Monitor

Example using arubaWiredTempSensorTemperature OID:

Select an Aruba (HPE) ArubaOS-CX wired switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type arubaWiredTempSensorTemperature into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the current temperature value read from the temperature sensor. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the reported value exceeds the level expected for healthy operation, since sustained high temperature often precedes thermal shutdown or hardware degradation. Click Finish to create the monitor; you can adjust any parameter later.
