Run the command show ap config general <AP name> and see this helps for your requirement. If you want to get the specific Info of the AP, use the command grep include "Key word" "show ap config general <AP name>" (Double quotes are required and Key word should exactly same on the output)
You can refer this CLI command details Cisco WLC for all the possible show commands on the AP.
Thank you so much for your reply. In comparison with logging on to AP to get configuration, the command you mentioned cannot get more info, am I right?
Yes, this command provide you the AP group , Native VLAN, Policy ACL's and etc details. Which you are performing through WLC.
