DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch CLI Manual
Used to configure the PoE port settings.
config poe ports [all | <portlist>] { state [enable | disable] | [time_range
<range_name32> | clear_time_range] | priority [critical | high | low] | power_limit
[class_0 | class_1 | class_2 | class_3 | user_define <value 1000-16800>]}
Configure the PoE port settings.
portlist - Specified the list of ports whose setting is under configuration.
all - Specifies that all ports will be used.
state - When the state is set to disable, power will not be supplied to the powered device
connected to this port.
time_range - Specifies the time range that applies to the port of the POE. If time range is
configured, the power can only be supplied during the period specified by time range.
clear_time_range - Remove the time range.
priority - Port priority determines the priority the system attempts to supply the power to 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_port, priority of
port will be used by the system to manage to supply power to ports.
power_limit - Configure the per-port power limit. If a port exceeds its power limit, it will be
shut down.
Based on 802.3af, there are 5 kinds of PD classes, class 0, class 1, class 2, and class 3. The
power consumption ranges for them are 0.44~12.95W, 0.44~3.84W, 3.84~6.49W,
6.49~12.95W, and 12.95~ 29.5W, respectively.
The five pre-defined settings are for 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_0 : 15400mW
class_1 : 4000mW
class_2 : 7000mW
clase_3 : 15400mW
Other than these four pre-defined settings, users can directly specify any value that the chip
supported, Normally, the minimum setting is 1000mW, and the maximum setting is 15400mW
for 802.3af and >=35000mW for 802.3at.
Only Administrator and Operator-level users can issue this command.
