Re: [8023-POEP] 2 Event Classification state diagram
Does this mean that an afPD could become an atPD by means of a software upgrade?
Then, if the PSE is an atPSE, the upgraded afPD could benefit from reclassification.

ANSWER:
Yes, an .atPD that wants 3.84, 6.49, or 12.95W would
use 1-1, 2-2, or 3-3 respectively.
In this case, the .atPSE does not know the .atPD is in
fact an .atPD. It thinks it is an .afPD. (The .atPD
does know the PSE is an .atPSE.)
Subsequently, if the .atPSE desires to use layer 2
classificaiton, it would need to poll the PD to see if
it responds. (Alternately, the .atPD could announce
to the PSE that it is an .atPD.)
