DGS-1100/ME Metro Ethernet Managed Switch CLI Reference Guide
config poe ports
Purpose To configure PoE system-wise function and port settings.
Syntax
config poe ports [all | portlist <portlist>] { state [enable |
disable] | time_range [ name <range_name 8> | clear] | priority
[critical | high | low] | power_limit [ auto | class_1| class_2 |
class_3| class_4| user_define <value m - n>]}(1)
Description To configure PoE port settings.
Parameters
[all | portlist <portlist>] – Specifies PoE ports to be used on the
switch.
state [enable | disable] - When the state is set to disable, power will
not be supplied to the powered device connected to this port.
time_range[name<range_name 8> | clear] - Specifies the time range
that applies to the port of the PoE.
priority [critical | high | low] - Port priority determines the priority level
for when the system attempts to supply the power to the port.
There are three levels of priority that can be selected, critical, high,
and low. When multiple ports happen to have the same level of
priority, the port ID will be used to determine the priority. The lower
port ID has higher priority. The setting of priority will affect the
ordering of supplying power. Whether the disconnect method is set
to deny low priority ports, priority of the port will be used by the
system to manage the power supply to the ports.
power_limit [auto | class_1 | class_2 | class_3 |
user_define <value m-n>] - Specifies the per-port power limit. If a
port exceeds its power limit, it will be shut down.
Based on the industry standard, 802.3af, there are 5 kinds of PD
classes, class 1, class 2, class 3, and class 4
3.84~6.49W, 6.49~12.95W, and 12.95~29.5W, respectively.
The five pre-defined settings are for the users’ convenience: The
following is the power limit applied to the port for these four classes.
For each class, the power limit is a little more than the power
consumption range for the class. This takes the factor of the power
loss on cable into account. Thus, the following are the typical values
defined by the chip vendor.
class_1 - 15400mW
class_2 - 4000mW
class_3 - 7000mW
clase_4 - 15400mW
user_define <value m-n> - Other than these four pre-defined
settings, the users can directly specify any value
