Hi ,

Please correct if my interpretation of LOCAL MAC is wrong.
WTP terminates 802.11 control packets and nothing is sent to AC .
WTP terminates 802.11 mangement frames and corresponding events are sent to 
AC.
WTP terminates 802.11 data frames, does decryption/encryption based on
unique keys correspond to wireless stations, extracts 802.3 packet from the
frame and send the frame across to AC. If needed, it might also send
some control information along with each 802.3 packet.
In this case, AC does not have knowledge of 802.11 header. It only needs 
knowledge of
CAPWAP protocol, 802.1x termination, specific wireless related parameters.

What makes it split MAC? My understanding is that, if AC terminates 802.11 
frames and
does encyption/decryption and has knowledge of 802.11 frames, then it is 
Split MAC.
Is this understanding correct?

Thanks
Rama Krishna
