Hai,

I have Cisco 9800 WLC, AP 1815i and 1562i.

1815i APs are joined and working fine.But 1562i Aps are not joining to the controller.

Kindly share your information to fix this issue.

Below is the logs from 1562i AP:

Dear Xayyam,

AP already got the controller IP from dhcp.

Is the AP meant to be in Bridge mode?

If not, the console into the AP and enter the following command:

capwap ap mode local

check your WLC - if 1562 ap is in bridge/mesh mode, then you will need to add the mac address of the 1562 AP into the WLC before it will join
