Selected Answer: AD
Poe Supplies up to 18.6 W of power. Poe+ Supplies up to 30 W of power. Poe Priority Set the power priority for individual interfaces when there is insufficient power for all PoE interfaces. If the switch needs to shut down powered devices because PoE demand exceeds the PoE budget, low-priority devices are shut down before high-priority devices.
