Viewing the PoE status on specific ports

Syntax:


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`.
Priority	Lists the power priority (Low, High, and Critical) configured on ports enabled for PoE. (For more on this topic, see Configuring PoE operation.)
Allocate by	How PoE is allocated (usage, class, value).
Detection Status	Searching: The port is trying to detect a PD connection. Delivering: The port is delivering power to a PD. Disabled: On the indicated port, either PoE support is disabled or PoE power is enabled but the PoE module does not have enough power available to supply the port's power needs. Fault: 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.
Voltage	The total voltage, in volts, being delivered to PDs.
Power	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.
Value	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: 0.44 to 12.95 watts 1: 0.44 to 3.84 watts 2: 3.84 to 6.49 watts 3: 6.49 to 12.95 watts 4: 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.
Current	The total current, in mA, being delivered to PDs.

If you want to view the PoE status of ports A6 and A7, you would use show power-over-ethernet A6-A7 to display the data:

Output for the show power-over-ethernet <port-list> command

switch(config)# show power-over-ethernet slot A6-A7
