I had a look to this command, but I read the documentation for it and think that the informations are only generated with roaming informations out of the WDS.
Is that true?
IOS command reference:
"Use the show dot11 adjacent-ap privileged EXEC command to display the fast, secure roaming list of access points that are adjacent to this access point. The WDS access point builds the adjacent access point list based on data from client devices that support fast, secure roaming. This command works only when you configure your wireless LAN for fast, secure roaming and there are client devices on your wireless LAN that support fast, secure roaming."
