Chapter 6 Deploying Wireless Networks for FortiOS 5.0 : Wireless network monitoring : Monitoring rogue APs
  
Monitoring rogue APs
The access point radio equipment can scan for other available access points, either as a dedicated monitor or as a background scan performed while the access point is idle.
Discovered access points are listed in the Rogue AP Monitor list. You can then mark them as either Accepted or Rogue access points. This designation helps you to track access points. It does not affect anyone’s ability to use these access points.
Rogue AP Settings (WiFi Controller > WiFi Network > Rogue AP Settings) control rogue AP detection for APs that use the Automatic profile. For APs that use a custom AP profile, rogue AP detection settings are contained in the custom AP profile (WiFi Controller > WiFi Network > Custom AP Profile).
It is also possible to suppress rogue APs. See “Suppressing rogue APs”.
