how to connect AP to WLC directly and how To configure the DHCP for this setup

[Scott Fella]

I’m assuming you have a 2504? That would be the only controller that you can connect an AP directly to. If you do have a 2594, then a dhcp would need to be created on the WLC for the same subnet as the WLC management. Then the AP can be connected to the WLC and the AP will get an IP address and join the WLC.

Yes we have 2504 , how AP will get the IP from WLC?How to configure the WLC for the same? Just for information AP is connected to PoE of WLC

You are better off using a switch and an external dhcp for reliability and stability. If you want to create a dhcp scope on the WLC. Just do a search on Google for “Cisco 2504 create dhcp scope”.

You will also find some scenarios here:

Please post more info like your config, console output from the AP, etc. we can’t help without more info.
