Displaying the PoE Status on Specific Ports
Syntax: show power-management [e] < 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.
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 7.)
Detection Status:
•
–� Searching: The port is available to support a PD
connection.
– Delivering: The port is delivering power to a PD.
– Disabled: PoE support is disabled on the port. To re-enable
PoE support, refer to "Configuring PoE Operation" on
page 7.
– Fault: The switch detects a problem with the connected PD.
• Over Current Cnt: Shows the number of times a connected PD
has attempted to draw more than 15.4 watts. Each occurance
generates an Event Log message.
Power Denied Cnt: Shows the number of times PDs requesting
•
power on the port have been denied due to insufficient power
available. Each occurance generates an Event Log message.
Voltage: The total voltage, in dV, being delivered to PDs.
•
Power: The total power, in mW, being delivered to PDs.
•
Configured Type:
•
• Power Class: Shows the power class of the PD detected on the
indicated port. Classes include:
0: 0.44w to 12.95w
1: 0.44w to 3.84w
2: 3.84w to 6.49w
3: 6.49w to 12.95w
4: reserved
• MPS Absent Cnt: This value shows the number of times a
detected PD has no longer requested power from the port.
Each occurance generates an Event Log message. ("MPS"
refers to the "Maintenance Power Signature". Refer to
"Terminology" on page 2.)
• 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.
