Table 1: show poe interface Output Fields

Field Name (All Interfaces Output)

Field Name (Single Interface Output)

Field Description

Interface

PoE Interface

Interface name.

Admin status

Administrative status

Administrative state of the PoE interface: Enabled or Disabled. If the PoE interface is disabled, it can provide network connectivity, but it cannot provide power to connected devices.

Oper status

Operational status

Operational state of the PoE interface:

  • ON—The interface is currently supplying power to a powered device.

  • OFF—PoE is enabled on the interface, but the interface is not currently supplying power to a powered device.

  • FAULT—PoE interface is in the OFF state due to a fault condition.

  • Disabled—PoE is disabled on the interface.

 

Operational status detail

Additional information for troubleshooting the operational state of the PoE interface:

  • Admin up but disabled on hardware—The interface is disabled due to power budget unavailability.

  • Overload—Interface is in the fault condition.

  • IEEE PD Detected—The interface is providing power to the powered device.

  • Detection In Progress—Detection of the powered device is ongoing.

 

FourPair status

Status of high-power mode of power delivery over all four pairs of the Ethernet cable:

  • Enabled—High power mode is enabled.

  • Disabled—High power mode is disabled.

Pair/Mode status

 

Shows the mode of power delivery configured on the interface.

  • 4P/AT—Interface is configured for high power mode.

  • 4P/POH—Interface is configured for ultra-high power mode.

  • DS/BT—Interface is configured for dual-signature powered devices.

  • SS/BT—Interface is configured for single-signature powered devices.

Max power

Power limit on the interface

Maximum power that can be provided by the interface.

An (L) next to the value indicates that the value on the port was negotiated by LLDP.

Priority

Priority

Interface power priority: either High or Low.

An (L) next to the value indicates that the value on the port was negotiated by LLDP.

Power consumption

Power consumed

Amount of power being used by the interface at the time the command is executed.

Class

Class of power device

IEEE PoE class of the powered device. Class 0 is the default class and is used when the class of the powered device is unknown. If no powered device is connected, this field contains not applicable.

PoE-bt supports power devices with dual signatures. For dual-signature devices, the output value contains both the class values, e.g. 5/5. For single-signature devices, the output value is formatted as 5/-.

PoE Mode

IEEE PoE standard supported by the interface—either 802.3af, or 802.3at, ultra-poe, or 802.3bt.
