3502 AP not join 5500 series WLC

                   I have 5508 wireless lan controller and 3502 AP. I did all configuration on WLC using the configuration guide. But AP don't join the WLC. AP can assign an IP address and i can ping this IP from WLC. When i connect the AP from console i see the logs below;

*Mar  1 15:36:57.128: %CAPWAP-3-ERRORLOG: Could Not resolve CISCO-CAPWAP-CONTROLL ER
Not in Bound state.
*Mar  1 15:37:42.637: %CAPWAP-3-DHCP_RENEW: Could not discover WLC using DHCP IP.  Renewing DHCP IP.
*Mar  1 15:37:46.730: %CAPWAP-3-ERRORLOG: Invalid event 38 & state 2 combination.
*Mar  1 15:37:46.793: %DHCP-6-ADDRESS_ASSIGN: Interface BVI1 assigned DHCP addres s, mask, hostname AP4c00.82e9.a218

Translating "CISCO-CAPWAP-CONTROLLER"...domain server (
*Mar  1 15:37:53.638: %CAPWAP-3-ERRORLOG: Did not get log server settings from DH CP.

I research similar problems in forums and i implement all they said but i can't solve the problem. there are also DHCP options below;

ddns-update-style interim;

     allow bootp;

     option space Cisco_LWAPP_AP;

     option Cisco_LWAPP_AP.server-address code 43 = string;

     subnet netmask {


     option routers;

     option subnet-mask;

     range dynamic-bootp;

     default-lease-time 300;

class "Cisco-AP-c3500" {

       match if option vendor-class-identifier = "Cisco AP c3500";

       option vendor-class-identifier "Cisco AP c3500";

       vendor-option-space Cisco_LWAPP_AP;

       option Cisco_LWAPP_AP.server-address f1:04:0a:11:07:0a; (Management IP : )



  What could be the cause of problem ??

Try changing your option 43 address to look like this:
