Hi Srikanth,
This is a complete different questions to what has been answered on this forum. I would suggest to open a new thread for proper follow up.
In order to help, more details are needed. Issue is too general as stated.
- what WLC?
- what APs?
- can AP reach WLC "show ap join stats summary all" & "show ap join stats detail <ap mac addr>"?
- How AP are able to discover WLC: DNS, Option 43, Broadcast ... ?
Regards,
Rafael
