Our customer has about 200 Autonomous APs(Version=c1200-k9w7-tar.123-2.JA2),WLSM(Maintenance img(1.1(2)),Application img=12.2(15)XR2), Sup720 IOS=s72033-jk9o3sv-mz.122-18.SXD3.bin.The static WDS point to WLSM,somme of AP will fail with log"Connection lost to WLCCP server, changing to Stand-Alone Mode".

Any ideas about solutions on this?

You will receive this error message if the AP loses its connectivity with the WDS. This can happen if the radios are flapping, as well as if there are problems with authentication / registration with WDS. If the AP is powered using POE, please ensure that you configure the proper poe support on them. Also check if authentication is happening correctly. Debugs on the AP and the logs on the AAA server will help troubleshoot this issue.
