Output Fields

Table 1 lists the output fields for the show poe interface command. Output fields are listed in the approximate order in which they appear.

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. `4P Port that deliver only 2 Pair non IEEE`—Signature failure on Alt-B, allowing power only on Alt-A (Non IEEE or Legacy PD). `4P Port delivering 2P non IEEE`—Non-IEEE PD was detected using 4P matrix in BT mode and power as 2Pair . `4P Port delivering 4P non IEEE`—Non-IEEE PD was detected using 4P matrix in BT mode and power as 4Pair. `4P Port delivering 2P IEEE SSPD`—802.3BT- SSPD was detected using 4P matrix and operate as 2P if requested class =< 4. `4P Port delivering 4P IEEE SSPD`—802.3BT- SSPD was detected using 4P matrix and operate as 4P if requested class > 4. `4P Port delivering 2P IEEE DSPD in 1st phase`—802.3BT- DSPD was detected using 4P matrix and operate as 2P due to 4pair candidate validation in two cycles. `4P Port delivering 2P IEEE DSPD`—802.3BT- DSPD was detected using 4P matrix and operate as 2P. `4P Port delivering 4P IEEE DSPD`—802.3BT- DSPD was detected using 4P matrix and operate as 4P. `Force Power BT 4P`—Port matrix 4P and delivers power on both pair sets due to force power command. `Force Power BT Error`—Force power command was set, one of the port pair sets stop delivering power, from at least one reason out of various reasons (System related, Device related, port related or Pair set related). `Connection Check error`—This error will be reported only in 4 pair port when invalid connection check signature was detected. In such case detection fail counter will be incremented. `Open`—Port is not connected (Equivalent to Detection in Progress).
	`FourPair status`	Status of four-pair PoE (PoE-4P), a Juniper Networks extension to the IEEE 802.3at standard, which can be enabled for high or ultra-high power delivery: `Enabled`—High or ultra-high power mode is enabled. `Disabled`—High or ultra-high power mode is disabled. See Enabling PoE on EX Series Switches (CLI Procedure) for information on how to enable four-pair PoE.
`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. This is determined by the class of the powered device. For dual-signature devices, each pair set has its own class. The maximum power will be the total of the maximum power for the two classes: `max power = class x + class y` for dual signature `x/y`. For example, a dual-signature device with a class value displayed as 5/5 has a maximum power of 90W, because class 5 has a maximum power of 45W. 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`.
