Parameters
critical: Sets the power supply priority to critical. The PSE with critical power priority operates in
guaranteed mode, and power is supplied to it first.
high: Sets the power supply priority to high.
low: Sets the power supply priority to low.
pse pse-id: Specifies a PSE by its ID.
Usage guidelines
If PSE power management is disabled, the system does not supply power to new PSEs when PoE
power overload occurs.
If PSE power management is enabled, when PSE power overload occurs, the system supplies
power to a PSE with higher priority. For multiple PSEs with the same priority, the PSE with a smaller
ID gets power supplied first.
For example, if PoE is enabled for a PSE, and the PSE has higher priority, the system performs the
following operations:
Stops supplying power to a PSE with lower priority.
Supplies power to the PSE that has higher priority.
Examples
# Set the power supply priority of PSE 7 to critical.
<Sysname> system-view
[Sysname] poe priority critical pse 7
