Manage Ports using Power Priority and the Power Budget
The allocation and return of power on ports depends on the total inline power available in the system and
the power priority calculation.
Determine the Power Priority for a Port
FTOS uses a sophisticated port prioritization algorithm for determining which ports receive power so that
PoE/PoE+ ports are powered up/down deterministically.
