display poe power-state

Function

The display poe power-state command displays the PoE power supply status of all interfaces or a specific interface.

Format

display poe power-state [ interface interface-type interface-number ]

Parameters

Parameter	Description	Value
interface interface-type interface-number	Specifies an interface: interface-type: specifies an interface type. interface-number: specifies an interface number. If no interface is specified, information about the PoE power supply status of all interfaces on the device is displayed.	The interface type must be GE; the interface number can be GE0/0/0, GE0/0/1, GE0/0/2, or GE0/0/3.

**Table 1** Description of the **display poe power-state interface** command output
Item	Description
Port legacy detect	Whether compatibility detection is enabled on an interface. You can run the poe legacy enable command to enable compatibility detection.
Port power enabled	Whether PoE is enabled. You can run the poe enable command to enable PoE.
Port power ON/OFF	Whether the interface supplies power: On Off
Port power status	Power supply status of the interface: Test mode Detecting Disabled: PoE is disabled on the interface. The reference power is greater than the maximum output power of the interface. Classification overcurrent Unknown: unknown level Power overcurrent Power-on failed Power-ready: The interface is ready to supply power. Delivering-power: The interface is supplying power. Overloaded Power off time range: The interface is in the power-off period. Legacy disable: Non-standard PD compatibility detection is disabled on the interface.
Port PD class	Class of a PD connected to the interface.
Port reference power(mW)	Reference power of the interface. The system automatically identifies the maximum power of the PD, classifies the PD, and defines the reference power of each class. Mappings between PD classes and reference power values are as follows: 0: The reference power is 15400 mW. 1: The reference power is 4000 mW. 2: The reference power is 7000 mW. 3: The reference power is 15400 mW. 4: The reference power is 30000 mW.
Port power priority	Power supply priority of the interface: Critical High Low You can run the poe priority command to set a power supply priority for the interface.
Port max power(mW)	Maximum output power of the interface. If the maximum output power is 15400 mW, the device supports 802.3af. If the maximum output power is 30000 mW, the device supports 802.3at. You can run the poe max-port-power command to set the maximum output power for the interface.
Port current power(mW)	Current output power of the interface.
Port peak power(mW)	Peak output power of the interface.
Port average power(mW)	Average output power of the interface.
Port current(mA)	Output current of the interface.
Port voltage(V )	Output voltage of the interface.
