xStack DGS-3400 Series Layer 2 Gigabit Managed Switch CLI Manual
config poe system
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:
The default setting is deny_next_port.
management_mode – Use this parameter to utilize the PoE management
mode function of this switch. The user has two choices:
Restrictions
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).
• power_limit - Choose this option to shut down the port if the power
limit on the port exceeds the limit stated by the user configured in
the power_limit field.
• auto - Choose this field to automatically disconnect the power from a
given port when it exceeds the maximum power used, as defined by
the PD’s (power device) power class, stated previously in this
section. When a PD is attached to a port on the Switch, the Power
Class is automatically determined. If the PD’s power class is
unspecified or there is an error in determining the power class, it is
given the power class zero (0).

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.
The port list is specified by listing the lowest switch number and the
beginning port number on that switch, separated by a colon. Then the
highest switch number, and the highest port number of the range (also
separated by a colon) are specified. The beginning and end of the port
list range are separated by a dash. For example, 1:3 specifies switch
