@mansiathakur123 Did you maybe post this in Cisco wireless forums by mistake?
These forums are about Cisco Wireless LAN Controllers (WLC) and Access points (AP) and related issues generally.
If you have a post about these you need a complete detailed description of the nature of the problem and any relevant screenshots, error messages and logs, what model of WLC, what version of software, what model of AP, how the WLAN is configured, what client you are testing with (OS and version, NIC model and driver version) for people to be able to help you.
