• CoS for Untrusted Ports—If Extended Trust is disabled on the port, this 
fields displays the Layer 2 CoS value, meaning, an 802.1D/802.1p priority 
value. This is the COS value with which all packets received on an untrusted 
port are remarked by the device.
• Request ID—Last power request ID received echoes the Request-ID field 
last received in a Power Requested TLV. It is 0 if no Power Requested TLV 
was received since the interface last transitioned to Up. 
• Power Management ID—Value incremented by 1 (or 2, to avoid 0) each time 
any one of the following events occur:
- Available-Power or Management Power Level fields change value
- A Power Requested TLV is received with a Request-ID field which is 
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.
