display poe power port

display poe power port


The display poe power port command displays current power information on ports.


display poe power port { port-num | all }





port-num Specifies the port number of a PoE midspan. The value is an integer that ranges from 0 to 7.
all Indicates all port numbers of a PoE midspan.

Usage Guidelines

The display poe power port command displays port information, including the actual output power and configured maximum output power of ports as well as class, reference power, and average power of PDs connected to ports.

Table 3-62  Description of the display poe power port command output



Port PD class

Class of a PD, which assesses the power required by the PD.

The system classifies PDs into five classes, class 0 to class 4, based on their maximum power.

Port PD power(mW)

Output power of the PD.

Port PD reference power(mW)

Reference power of the PD, in mW.

The system can identify the reference power of each PD. The value varies depending on PD types. The mapping between PD classes and the reference power is as follows:

  • 0: The reference power is 15.4 W.
  • 1: The reference power is 4 W.
  • 2: The reference power is 7 W.
  • 3: The reference power is 15.4 W.
  • 4: The reference power is 30 W.

Port user set max power(mW)

Maximum output power configured for the port, in mW.

To configure this parameter, run the poe power port command.

Port PD peak power(mW)

Peak power of the PDs connected to the port, in mW.

The value is a statistical value, which equals the current maximum power consumption of the PDs connected to the port.

Port PD average power(mW)

Average power of the PDs connected to the port, in mW.

The value is a statistical value, which equals the average power consumption from the power-on of the port till now.
