any one of the following events occur:
- Available-Power or Management Power Level fields change value

different from the last-received set (or when the first value is received)
- The interface transitions to Down
• Available Power—Amount of power consumed by port.
• Management Power Level—Displays the supplier's request to the powered
device for its Power Consumption TLV. The device always displays “No
Preference” in this field.
