config poe system
deny_low_priority_port}
Description Allows
the
user to configure the parameters for the whole PoE
system.
Parameters
power_limit
The power limit parameter allows the user to
configure the power budget of whole PoE system. The minimum
setting is 37 W and the maximum is 370W (depending on the power
supplier’s capability). Default setting is 370 W.
power_disconnect_method
This parameter is used to configure
the power management disconnection method. When the total
consumed power exceeds the power budget, the PoE controller
initiates a port disconnection to prevent overloading the power
supply. The controller uses one of the following two ways to
implement the disconnection:
deny_next_port
After the power budget has been exceeded,
the next port attempting to power up is denied, regardless
of its priority.
deny_low_priority_port
After the power budget has been
exceeded, the next port attempting to power up, causes the
port with the lowest priority to shut down (to allow high-
priority ports to power up).
The default setting is
deny_next_port
.
Restrictions
Only Administrator-level users can issue this command.
Example usage:
To config the PoE System on the Switch:
DES-3028P:4#config
poe system power_limit 185
power_disconnect_method deny_next_port
Command: config poe system power_limit 185
power_disconnect_method deny_next_port
Success.
DES-3028P:4#
config poe ports
Purpose
Used to configure the PoE port settings.
Syntax
config poe ports [all | <portlist>] {state [enable | disable] |
priority [critical | high | low] | power_limit [class_0 | class_1 |
class_2 | class_3 | user_define <value 1000-16800>]}
Description The
config poe ports
command is used to configure the PoE port
settings.
Parameters
<portlist>
Specifies a range of ports to be configured or all the
ports.
all
– Specifies that all ports on the Switch will be configured for
PoE.
state
Enables or disables the PoE function on the Switch.
priority
Setting the port priority affects power-up order and
shutdown order.
Power-up order
: When the Switch powers-up or
reboots, the ports are powered up according to their priority (
critical
first, then
high
and finally
low
).
Shutdown order
: When the power
limit has been exceeded, the ports will shut down according to their
