ports. These ports will be the first ports to receive power 
and the last to disconnect power. 
high – Specifying this parameter will nominate these ports 
as having the second highest priority for receiving power 
and shutting down power.

low – Specifying this parameter will nominate these ports 
as having the lowest priority for receiving and shutting 
down power. These ports will be the first ports to have 
their power disconnected if the 
power_disconnect_method chosen in the config poe 
system
 command is deny_low_priority_port
power_limit – Allows the user to configure the per-port power limit. 
If a port exceeds its power limit, the PoE system will shut down that 
port. The minimum user-Defined setting is 1000mW and maximum 
is 16800mW. The default setting is 15400mW. The user may also 
choose to define a power class by which to set the power limit, 
based on the PSE table at the beginning of this section. 
Restrictions 
User Account Command Level – Administrator and Operator 
class_0 – Choosing this class will set the maximum port 
limit at 15.4W.  
class_1 - Choosing this class will set the maximum port 
limit at 4.0W. 
class_2 - Choosing this class will set the maximum port 
limit at 7.0W. 
class_3 - Choosing this class will set the maximum port 
limit at 15.4.0W. 
user_define – Choosing this parameter will allow the user 
to set a power limit between 1000 and 16800mW with a 
default value of 15400mW. 
Example usage: 
 
To config the Switch’s ports for PoE: 
DES-3028P:4#config poe ports 1-3 state enable priority critical power_limit class_0 
Command: config poe ports 1-3 state enable priority critical power_limit class_0 
 
Power limit has been set to 15400mW(Class 0 PD upper power limit 12.95W + power loss 
on cable). 
Success. 
 
DES-3028P:4# 
 
show poe system 
Purpose 
Used to display the setting and actual values of the whole PoE 
system. 
Syntax 
show poe [system | ports {<portlist>}] 
Description 
Display the settings, actual values and port configuration of the 
whole PoE system. 
Parameters 
system – Choosing this parameter will display the system settings for 
PoE, such as switch power limit, consumption, remaining useable 
power and the power disconnection method. 
ports – Choosing this parameter will display the settings for PoE on 
a port-by-port basis. 
portlist – Enter a port or range of ports to be displayed for their 
PoE settings.
