show power-over-ethernet


show power-over-ethernet <PORT-LIST>


Displays the following PoE status and statistics (since the last reboot) for each port in <PORT-LIST>:

Power Enable

Shows Yes for ports enabled to support PoE (the default) and No for ports on which PoE is disabled. For ports on which power is disabled, this is the only field displayed by show power-over-ethernet <PORT-LIST> .


Lists the power priority (Low, High, and Critical) configured on ports enabled for PoE.

Allocate by

How PoE is allocated (usage, class, value.)

Detection Status


The port is available to support a PD.


The port is delivering power to a PD.


PoE power is enabled on the port but the PoE module does not have enough power available to supply the port's power needs.


The switch detects a problem with the connected PD.

Other Fault

The switch has detected an internal fault that prevents it from supplying power on that port.

Over Current Cnt

Shows the number of times a connected PD has attempted to draw more than 15.4 watts for PoE or 24.5 watts for PoE+. Each occurrence generates an Event Log message.

Power Denied Cnt

Shows the number of times PDs requesting power on the port have been denied because of insufficient power available. Each occurrence generates an Event Log message.


The total voltage, in volts, being delivered to PDs.


The total power, in watts, being delivered to PDs.

LLDP Detect

Port is enabled or disabled for allocating PoE power, based on the link-partner's capabilities via LLDP.

Configured Type

If configured, shows the user-specified identifier for the port. If not configured, the field is empty.


The maximum amount of PoE power allocated for that port (expressed in watts.) Default: 17 watts for PoE; 33 watts for PoE+

Power Class

Shows the power class of the PD detected on the indicated port. Classes include:

0.44 to 12.95 watts


0.44 to 3.84 watts


3.84 to 6.49 watts


6.49 to 12.95 watts


For PoE+; up to 25.5 watts can be drawn by the PD

MPS Absent Cnt

Shows the number of times a detected PD has no longer requested power from the port. Each occurrence generates an Event Log message. ("MPS" refers to the "maintenance power signature.")

Short Cnt

Shows the number of times the switch provided insufficient current to a connected PD.


The total current, in mA, being delivered to PDs.

PoE status of ports
