Power Over Ethernet (PoE) Operation
Viewing PoE Configuration and Status
Ports C1 through C4 are
delivering power. The
remaining ports are
available to supply power,
but currently do not detect
a connected PD.
Figure 11-3. Example of Show Power-Management Brief Output
Displaying the PoE Status on Specific Ports
Syntax: show power-management < 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. Note t ha t
for ports on which power is disabled, this is the only field
displayed by show power-management < port-list >.
• Priority: Lists the power priority (Low, High, and Critical)
configured on ports enabled for PoE. (For more on this topic,
refer to the power command description under “Configuring
PoE Operation” on page 11-14.)
• Detection Status:
– Searching: The port is available to support a PD.
– Delivering: The port is delivering power to a PD.
– Disabled: PoE power is enabled on the port 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. Each
occurrence generates an Event Log message.
