69-1 config poe ports
Description
This command is used to configure the PoE port settings.
Format
config poe ports [all | <portlist>] {state [enable | disable] | [time_range <range_name 32> |
clear_time_range] | priority [critical | high | low] | power_limit [class_0 | class_1 | class_2 |
class_3 | user_define <value 1000-35000>]}
Parameters
ports - Specifies the list of port used for this configuration.
all - Specifies that all the ports will be used for this configuration.
<portlist> - Enter the list of ports, used for this configuration, here.
state - (Optional) Specifies whether power will be supplied to the powered device connected to this
port or not.
enable - Specifies that PoE will be enabled of the specifies port(s).
disable - Specifies that PoE will be disabled of the specifies port(s).
time_range - (Optional) Specifies the time range that applies to the port of the PoE. If the time range
is configured, the power can only be supplied during the period specified by the time range.
<range_name 32> - Enter the time range name used here. This name can be up to 32 characters
long.
clear_time_range - Specifies that the time range will be removed.
priority - (Optional) Port priority determines the priority 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 port, priority of port
will be used by the system to manage the power supply to the ports.
