Re: 802.11 frame translation :- WLC or AP or Both ?
The 802.3 mac headers are stripped at the controller and the 802.11 header is added. Then the entire frame has a CAPWAP or LWAPP headder, new IP header, and new mac header added on top of the 802.11 header. The now encapsulated packet is sent out of the controller to the AP where the mac, outter IP, and CAPWAP/LWAPP header is removed and the 802.11 packet is transmitted out the AP. So the conversion from an 802.3 to 802.11 packet happens at the controller but there is a new 802.3 header applied so the packet can be sent over the wire between the AP and controller.
