POE COMMANDS
The PoE commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in
the following table.
Command Parameter
config poe
box_id <value 1-6> system_power_limit [ps1 | ps2 | ps3] disconnect_method
[deny_next_port | deny_low_priority_port]
config poe ports
<portlist> { state [enable | disable] | priority [low | high | critical] | power_limit
<value 1-15400>}
show poe
Each command is listed in detail, as follows:
config poe
Purpose To configure the parameters for the whole PoE system.
Syntax
config poe box_id <value 1-6> system_power_limit [ps1 | ps2 |
ps3] disconnect_method [deny_next_port |
deny_low_priority_port]
Description The config poe command configures the parameters for the PoE
system on a unit member of the stack.
Parameters box_id <value 1-6> – The unit’s current stack membership number.
system_power_limit [ps1 | ps2 | ps3] – Specifies the power budget of
the whole PoE system, according to the type of power supply used
(ps1, ps2, ps3).
disconnect_method – Configures 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. This is the default
setting.
• 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).
Restrictions Only administrator-level users can issue this command.
Example usage:
To config the PoE System on the Switch:
DGS3100# config poe system_power_limit 300 disconnect_method deny_next_port
Success.
