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

Any view

interface-type interface-number: Specifies an interface by its type and number.

Use the display poe interface power command to display the power 
information of a PoE interface(s).

If no interface is specified, the power information of all PoE interfaces is displayed.

Operating Status 

Operating state of a PoE interface

■

off: PoE is disabled.

■

on: Power is supplied for a PoE interface normally.

■

power lack: The guaranteed remaining power of the PSE is not high 
enough to supply power for a critical PoE interface.

■

power-deny: The PSE refuses to supply power. The power required by 
the powered device (PD) is higher than the configured power.

■

power-itself: The external equipment is supplying power for itself.

■

power-limit: The PSE is supplying a limited power. The power required 
by the PD is higher than the configured power and the PSE still supplies 
the configured power.

Different models of device support different operating states. 

IEEE class 

PD power class stipulated by IEEE 

Detection Status 

Power detection state of a PoE interface:

■

disabled: The PoE function is disabled.

■

searching: The PoE interface is searching for the PD.

■

delivering-power: The PoE interface is supplying power for the PD.

■

fault: There is a fault defined in 802.3af.

■

test: The PoE interface is under test.

■

There is a fault other than defined in 802.3af.

■

pd-disconnect: The PD is disconnected.

Different models of device support different power detection states.
