Hi All:

My WLC already firmware already update to latest version 6.0 and the management ip and ap manager ip in the same subnet, DNS record already have the CISCO-LWAPP-CONTROLLER and CISCO-CAPWAP-CONTROLLER A record.But Some lightweight AP cannot join the WLC and the error message in WLC as below :

---------------------------------------
