You can also show the PoE information by slot:
Showing the PoE information by slot
switch(config)# show power-over-ethernet slot A
Status and Counters - System Power Status for slot A
Maximum Power : 408 W Operational Status : On
Power In Use : 9 W +/- 6 W Usage Threshold (%) : 80
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 on page 109.)
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+
