Description: Manages Power over Ethernet port configuration and status on Aruba wired CX switches.

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-POE-MIB?

This is an HPE Aruba proprietary MIB for ArubaOS-CX wired switches that manages Power Sourcing Equipment (PSE) — the Power over Ethernet capability that powers devices like IP phones, access points, and cameras over Ethernet ports. It exposes per-port PoE configuration (power allocation method, pre-standard detection, power reservation) and detailed electrical/power runtime data (current, voltage, power drawn, average and peak power) along with port PoE operational status. This is a strong hardware/power health MIB: an administrator monitors arubaWiredPoePethPsePortPowerDrawn, arubaWiredPoePethPsePortCurrent, and arubaWiredPoePethPsePortVoltage against arubaWiredPoePethPsePortReservedPower to catch a port nearing its power budget, and checks arubaWiredPoePethPsePortOperStatus to confirm a port is actually delivering power to its connected device (a common way to detect a failed PoE injector or an overloaded power supply). It aligns conceptually with the standard IETF POWER-ETHERNET-MIB (RFC 3621) PSE port model, though implemented here as an Aruba-specific extension. It is deployed on ArubaOS-CX PoE-capable switches in enterprise networks powering phones, wireless APs, and other PoE endpoints, where ARUBAWIRED-POE-MIB SNMP monitoring is the standard way to track per-port power draw and catch faults early.

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

Aruba ArubaOS-CX wired switch (PoE-capable)

Monitoring Examples

An administrator polls arubaWiredPoePethPsePortTable to check arubaWiredPoePethPsePortPowerDrawn and arubaWiredPoePethPsePortPeakPower against arubaWiredPoePethPsePortReservedPower for each port, and verifies arubaWiredPoePethPsePortOperStatus shows the port is delivering power. A port whose arubaWiredPoePethPsePortOperStatus flips to a fault state, or whose average power (arubaWiredPoePethPsePortAveragePower) suddenly drops to zero, indicates a connected PoE device has lost power or the port has tripped a fault condition.

What Can Be Monitored

per-port PoE operational status
power drawn/current/voltage per port
reserved and peak power per port
power allocation method configuration

How to Use in IPNetwork Monitor

Example using arubaWiredPoePethPsePortInvalidSignatureCounterPairA 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 arubaWiredPoePethPsePortInvalidSignatureCounterPairA 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. This counter is incremented when the PSE state diagram enters the state SIGNATURE_INVALID, if alt_pri='a'. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

arubaWiredPoeMIB	1.3.6.1.4.1.47196.4.1.1.3.8			This MIB module describes management objects that manage Power Source Equipment (PSE). This is the MIB module related to HPE Aruba PoE
arubaWiredPoePethPsePort	1.3.6.1.4.1.47196.4.1.1.3.8.1
arubaWiredPoePethPsePortTable	1.3.6.1.4.1.47196.4.1.1.3.8.1.1		not-accessible	A table of objects that display and control the power characteristics of power Ethernet ports on a Power Source Entity (PSE) device. This group will be implemented in managed power Ethernet switches and mid-span devices. Values of all read-write objects in this table are persistent at restart/reboot.
arubaWiredPoePethPsePortEntry	1.3.6.1.4.1.47196.4.1.1.3.8.1.1.1		not-accessible	The fields in these entries will be used to supplement fields in 'pethPsePortEntry in ieee802af.mib.

Two power allocation strategies are class(2) and usage(1). When allocating by usage(1) power is delivered as requested by a PD. When allocating by class(2) the PSE uses the power ramp-up signature of the PD to identify the PD's power class and use the power level for the specified class.
INT arubaWiredPoePethPsePortPreStdDetect	1.3.6.1.4.1.47196.4.1.1.3.8.1.1.1.2	INTEGER	read-only	This field specifies the pre standard detect configuration for this port. A value of on - indicates that pre-802.3af-standard devices to power on. A value of off - indicates that only pre-802.3at/bt compliant devices are allowed. The default value is off.
INT arubaWiredPoePethPsePortRpd	1.3.6.1.4.1.47196.4.1.1.3.8.1.1.1.3	INTEGER	read-only	Rapid Power Down is executed by the hardware in the event of a power-supply failure. It quickly cuts power to a PD to prevent an over-current scenario in the PSE. This field indicates whether the interface will go down in the event of any PSU failure or not. A value of on(2) indicates that a power supply failure will cause the power delivery to be cut on supply failure. A value of off(1) indicates that the port is unaffected by the failure of any single PSU.The default value is off(1).

INT arubaWiredPoePethPsePortOperStatus	1.3.6.1.4.1.47196.4.1.1.3.8.1.1.1.10	INTEGER	read-only	This field specifies the operational status of the port.
INT arubaWiredPoePethPsePortPdSignature	1.3.6.1.4.1.47196.4.1.1.3.8.1.1.1.11	INTEGER	read-only	This Signature value represents the PD signature. This variable is valid only while a PD is detected. In 802.3af and 802.3at standards the power controller on the PSE uses two of the four pairs of wires in the RJ45 connector to supply power to a power controller on the PD. With 802.3bt standard the controller on the PSE uses all four pairs. On the PD side there can either be single power controller, or two distinct power controllers connected to each of the two pairs and each of the two controllers would negotiate and draw power independently from the PSE. The Controller on the PSE is capable of detecting the PD signature, which will indicate whether the PD comprises a single controller or two independent controllers. Possible values: unknownSignature : 2-pair mode, singleSignature : 4-pair mode and one controller on the PD side, dualSignature : 4-pair mode and two controllers on the PD side.

Classification is a way to tag different terminals on the Power over LAN network according to their power consumption. Devices such as IP telephones, WLAN access points and others, will be classified according to their power requirements. The meaning of the classification labels is defined in the IEEE specification. This variable is valid only while a PD is being powered, that is, while the attribute pethPsePortDetectionStatus is reporting the enumeration deliveringPower.

Class demotion allows the PSE to allocate less than the PD requested power based on the PD requested power and PSE available power. This information is published to the PD via the LLDP protocol. This read-only value indicates the PSE assigned class on this port. This variable is valid only while a PD is being powered, that is, while the attribute pethPsePortDetectionStatus is reporting the enumeration deliveringPower.
