APs that are converted to Lightweight AP Protocol (LWAPP) do not support
Wireless Domain Services (WDS). LWAPP−converted APs communicate only with
Cisco Wireless LAN (WLAN) Controllers (WLCs) and cannot communicate with
WDS devices. However, the WLC provides functionality that is equivalent to the
WDS when the AP associates to the WLC.
♦ 
Converted access points support 2006, 4400, and WiSM controllers only. When you
convert an autonomous access point to lightweight mode, the access point can
communicate with Cisco 2006 series controllers, 4400 series controllers, or the
controllers on a Cisco WiSM only.
♦ 
In controller software release 4.2 or later, all Cisco lightweight access points support
16 BSSIDs per radio and a total of 16 wireless LANs per access point. In previous
releases, they supported only 8 BSSIDs per radio and a total of 8 wireless LANs per
access point. When a converted access point associates to a controller, only wireless
LANs with IDs 1 through 16 are pushed to the access point.
♦ 
APs that are converted to LWAPP must get an IP address and discover the WLC with
use of DHCP, a Domain Name System (DNS), or an IP subnet broadcast.
♦ 
APs that are converted to LWAPP do not support Layer 2 LWAPP.
♦ 
APs that are converted to LWAPP provide a read−only console port.
♦ 
The upgrade conversion tool adds the self−signed certificate (SSC) key−hash to only
one of the controllers on the Cisco WiSM. After the conversion has been completed,
add the SSC key−hash to the second controller on the Cisco WiSM by copying the
SSC key−hash from the first controller to the second controller. In order to copy the
SSC key−hash, open the AP Policies page of the controller GUI (Security > AAA >
AP Policies
), and copy the SSC key−hash from the SHA1 Key Hash column under
AP Authorization List . Then, with the GUI of the second controller, open the same
page and paste the key−hash into the SHA1 Key Hash field under Add AP to
Authorization List. If you have more than one Cisco WiSM, use WCS to push the
SSC key−hash to all the other controllers.

Q. I have converted my access point to lightweight mode, but I need to
convert it back to autonomous mode. Is it possible?
A. Yes, you can convert autonomous APs that you have converted to lightweight mode back
to autonomous mode. Complete the steps in the Converting a Lightweight Access Point Back
to Autonomous Mode
 section of Upgrading Autonomous Cisco Aironet Access Points to
Lightweight Mode.
Q. How many access points can be converted via the upgrade tool at one
time?
A. With the latest 2.01 version of the tool, you can upgrade a maximum of six APs at a time.
