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 87.)
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.
