Wireless problem with DHCP

[ahmad_zoua]

I have a Cisco 2504 with Image 7.4.121.0 and AP 2702I with image 15.3(3)JA, i did a small lab and i connect the ap directly to the POE port on the controller and I did all configuration correct and made the controller a DHCP. However the AP is getting IP but with following error:

*Mar  1 01:43:32.639: %CAPWAP-3-DHCP_RENEW: Could not discover WLC. Either IP address is not assigned or assigned IP is wrong. Renewing DHCP IP.

*Mar  1 01:43:35.711: %DHCP-6-ADDRESS_ASSIGN: Interface BVI1 assigned DHCP address 10.1.1.11, mask 255.255.255.0, hostname AP881d.fca9.5310

I read about it and everybody is talking about option 43, I tried to activate this option on the controller but i think it doesn't support.

please advice.

Seems like compatibility issue;

access violation
