Re: [8023-POEP] Claasification Ad hoc - Enhanced classification scheme



Folks

If you are considering multi-cycle classification schemes, then is there any 
merit in extending this so that the PD can return additional information that 
identifies it? Such as a Vendor ID and Device ID?

If the data was returned LSB first (that is, Device ID bits 0 and 1) then such a 
scheme could be compatible with Christian's proposed ping-pong scheme (device ID 
LS bits denote power rating) - with the subsequent bits of Device ID and Vendor 
ID being optional.

If the PD returns 2 bits per cycle then 16 cycles (or 17 to account for the 
initial af classification) would return a 16-bit Vendor ID and 16-bit Device ID.

Maybe that could help the PSE decide what type of PDs should get power and who 
should not, and allow for non-intelligent applications (such as LED lighting).
