Quidway S6500 Series Ethernet Switches Chapter 1 PoE Configuration Commands
Huawei Technologies Proprietary
1-13
Description
Using the poe power-management command, you can configure the PoE
management mode of the switch.
Using the undo poe power-management command, you can restore the default
mode.
By default, the PoE management mode of the switch is auto.
This command and the port priority settings will work together to control the power
feeding of the switch when the switch is reaching its full power load in power supply.
z auto mode: When the switch is reaching its full load in supplying power, it will first
supply power to the PDs that are connected to the ports with critical priority, and
secondly supply power to the PDs that are connected to the ports with high priority.
For example: Port A has the priority of critical. When the switch is reaching full
load and a new PD is now added to the port A, the switch will power down a PD
that is connected to a port with the lowest priority and turn to feed this new PD.
z manual mode: When the switch is reaching its full load in supplying power
externally and a new PD is added, it will neither take the priority into account nor
make change to its original power supply status; only the infomation about the
newly added device is provided. For example: Port A has the priority of critical.
When the switch is reaching full load and a new PD is now connected to port A, the
switch does not supply power to this new device.
