Disabling CDP for AP

[yasseryy]

I want to disable the CDP protocol for a port connecting AP. In this case, how can I manually configure the WLC to discover and manage the AP?

You don’t configure the WLC to discover the AP, the AP needs to discover the WLC. Here is a link to read: https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-lan-wlan/70333-lap-registration.html

Now if disabling CDP prevents your AP from negotiating PoE, then you might need to enable CDP. So make sure your AP boots and negotiates PoE properly by connecting via console and looking at the output. The output will tell you a lot of things including the WLC discovery.
