config poe ports
Description
Used to configure the PoE port settings.
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
●
Class 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.

Parameters
●
ports - Specified the list of ports whose setting is under configuration.
●
all - Specifies that all the ports will be included in this configuration.
●
<portlist> - Enter the list of port used for this configuration here.
●
state - (Optional) When the state is set to disable, power will not be supplied to the powered device
connected to this port.
●
enable - Specifies that state will be enabled.
●
disable - Specifies that state will be disabled.
●
time_range - (Optional) 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.
●
<range_name 32> - Enter the time range name here. This name can be up to 32 characters long.
●
clear_time_range - (Optional) Remove the time range.
●
priority - (Optional) 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
