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>]} (1)
Description
This 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 number 1,
port 3. 2:4 specifies switch number 2, port 4. 1:3–2:4 specifies all of the ports between
switch 1, port 3 and switch 2, port 4 − in numerical order. Non–contiguous portlist entries
are separated by a comma. (ex: 1:1–1:3,1:7–1:9)
all – Specifies that all ports on the Switch will be configured for PoE.
state – Enables or disables the PoE function on the Switch.
priority – Setting the port priority affects power–up order and shutdown order. Power–up
order: When the Switch powers–up or reboots, the ports are powered up according to
their priority (critical first, then high and finally low). Shutdown order: When the power limit
has been exceeded, the ports will shut down according to their priority if the power
disconnect method is set to deny_ low_priority_port.
• critical – Specifying this parameter will nominate these ports has having the
highest priority for all configured PoE ports. These ports will be the first ports to
receive power and the last to disconnect power.
• high – Specifying this parameter will nominate these ports as having the second
highest priority for receiving power and shutting down power.
• low – Specifying this parameter will nominate these ports as having the lowest
priority for receiving and shutting down power. These ports will be the first ports
to have their power disconnected if the power_disconnect_method chosen in the
config poe system command is deny_low_priority_port.
power_limit – Allows the user to configure the per–port power limit. If a port exceeds its
power limit, the PoE system will shut down that port. The minimum user–defined setting is
1000mW and maximum is 16800mW. The default setting is 15400mW. The user may
also choose to define a power class by which to set the power limit, based on the PSE
table at the beginning of this section.
• class_0 – Choosing this class will set the maximum port limit at 15.4W.
• class_1 – Choosing this class will set the maximum port limit at 4.0W.
• class_2 – Choosing this class will set the maximum port limit at 7.0W.
• class_3 – Choosing this class will set the maximum port limit at 15.4.0W.
• user_define – Choosing this parameter will allow the user to set a power limit
between 1000 and 16800mW with a default value of 15400mW.
