hi Friends,
I am trying to configure a WLC and access points which must be connected to it as a part of my company's requirement. I configured the WLC and now i can access it via GUI. I have the initial configuration done on the WLC. I am trying to connect an Access point to it and it would not happen.
I am doing this on a lab setup and so, i created the DHCP server and the DNS server inside the Cisco 3650 i am using to connect all these devices. So, please let me know where i would be going wrong.
I am sharing the logs i captured. Please let me know if anything is wrong with my config. Thank you very much for helping me out in advance.
