display poe power-state port

display poe power-state port

Function

The display poe power-state port command displays the PoE power supply status of the device.

Format

display poe power-state port port-num

Parameters

Parameter

Description

Value

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

Usage Guidelines

The display poe power-state port command displays PoE power supply information on a specified port, such as compatibility detection status on the port, class of the PD connected to the port, and power supply status, power supply priority, as well as maximum output power of the port.

Table 3-63  Description of the display poe power-state port command output

Item

Description

Port legacy detect

Whether a port is enabled to check compatibility of PDs.

To configure this parameter, run the poe legacy enable port command.

Port power enabled

Whether PoE power supply is enabled on the port.

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

Port power ON/OFF

Whether the port is providing power:
  • On: The port is providing power.
  • Off: The port is not providing power.

Port power status

Power supply status of the port:

  • Test mode: The port is in testing state.
  • Detecting: The port is in detecting state.
  • Disabled: The PoE function is disabled on the port.
  • Chip fault: The chip of the port fails.
  • Power-deny: The reference power is higher than the maximum output power of the port.
  • Classification overcurrent: The current of the PD connected to the port exceeds the threshold.
  • Unknown class: The class of the PD is unknown.
  • Power overcurrent: The current of the PD exceeds the maximum current of the port.
  • Power-on failed: The port fails to power on the PD.
  • Power-ready: The port is ready to provide power to the PD.
  • Delivering-power: The port is providing power to the PD.
  • Over loaded: The port is in power overload state.
  • Power off time range: The PD connected to the port is powered off.

Port PD class

Class of the PD connected to the port.

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

Port reference power(mW)

Reference power of the port, in mW.

The system can identify the maximum power of a PD, classify the PD into a certain class, and define the reference power of each class. The mappings between PD types and reference power values are:

  • 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 power priority

Power supply priority of the port:
  • critical: the highest priority
  • high: the second highest priority
  • low: the lowest priority

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

Port max power(mW)

Maximum output power of the port, in mW.

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

Port current power(mW)

Current output power of the port, in mW.

Port peak power(mW)

Peak output power of the port, in mW.

Port average power(mW)

Average output power of the port, in mW.

Port current(mA)

Output current of the port, in mA.

Port voltage(V )

Output voltage of the port, in V.
