poe power-policy port-index-priority disable
Function
The poe power-policy port-index-priority disable command disables the device from powering on or off PDs connected to interfaces based on the interface numbers.
The undo poe power-policy port-index-priority disable command enables the device to power on or off PDs connected to interfaces based on the interface numbers.
By default, a device powers on or off PDs connected to interfaces based on the interface numbers.
Only the S5720-EI and S5720-HI support this function.

Usage Guidelines
- Preferentially provides power to PDs connected to the interface with a higher power supply priority.
- Preferentially provides power to PDs connected to the interface with a smaller interface number if interfaces have the same power supply priority.
According to the rules, when the PoE power of a device is insufficient and interfaces connected to PDs have the same power supply priority, the device may power off PDs connected to the interface with a larger interface number to power on PDs connected to the interface with a smaller interface number even if these PDs are connected to the device last.
To prevent this problem, you can run the poe power-policy port-index-priority disable command to disable the device from powering on PDs connected to interfaces based on the interface numbers. Subsequently, when the PoE power is insufficient, the device does not power on the PDs that are connected later regardless of which interface they are connected to and does not power off the PDs that have been powered on.
