13 Ethernet
Notes
When this command is set or deleted, the new setting is applied after the Switch is
restarted.
13.11.3 Setting port priority
The Switch uses PoE with three priority levels. If the amount of available power is
insufficient, a port with a lower priority level loses power earlier. If you do not want the
Switch to supply power to specific ports, you can stop the supply of power to those ports.
Points to note
If a device that you want to connect is a PoE-powered device and you do not want to
supply PoE power from the Switch, or if a remote device to which you want to
connect is also a PoE-power sourcing equipment, set the
port.
In the example below, port
it.
Notes
If PoE ports of the Switch are used to connect to a PSE, make sure that you set
never as the power supply priority level for these ports. If you do not stop the supply
of power to a PSE, an overload might be detected, resulting in the output of a
message. If the power supplied from the remote PSE can be stopped, we
recommend also stopping the power supplied from the remote PSE.
Command examples
1.
(config)# interface fastethernet 0/10
(config-if)# power inline never
Configures a specific port so that PoE does not supply power to it.
2.
(config-if)# exit
13.11.4 Setting so that priority is given to powered ports
When port priority is disabled and priority is given to the powered ports, power is first
supplied to the PDs connected earlier. When the total power consumption is over 370.0 W,
even if a power-receiving device is connected to a port with priority set as
will not be supplied.
Points to note
You can disable the port priority setting configured by the
configuration command and give priority to powered ports as follows.
Command examples
1.
(config)# power inline priority-control disable
Please execute the reload command after save,
because this command becomes effective after reboot.
Disables the port priority setting, and gives priority to powered ports. A message
appears that asks you to save the settings and restart the device.
2.
(config)# exit
# copy running-config startup-config
Do you wish to copy from running-config to startup-config? (y/n): y
