When the Radio Role of the wireless security appliance is set to Access Point mode, all three types of WIDS services are available, but Rogue Access Point detection, by default, acts in a passive mode (passively listening to other Access Point Beacon frames only on the selected channel of operation). Selecting Scan Now momentarily changes the Radio Role to allow the wireless security appliance to perform an active scan, and may cause a brief loss of connectivity for associated wireless clients. While in Access Point mode, the Scan Now function should only be used if no clients are actively associated, or if the possibility of client interruption is acceptable.
