Hi Shiv.
The link below might be something what you require:
http://www.cisco.com/warp/public/102/wlan/leapserver.html
But, Cisco does not recommend using the CLI for configuring the AP 1100/1200 series access points. Cisco has done a great job by making the GUI have almost all the necessary features required to configure the APs. Partially configuring from the CLI and partially using the GUI might lead to unexpected results.

Abdulla.
