Viewing PoE Configuration and Status 

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: 

Shows the type of PD detected on the port. 

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.
