We operate 2 x Aruba7220 (master & local) controllers running AOS 6.4.3.2 and deployed AP105/135/205 APs in various spaces. Lately, an increasing number of clients are being constantly kicked off our reliable and secure Production-SSID to a slow and open Guest-SSID. A closer inspection of the logs show a <WARN> of Disconnect Station Attack: An AP detected a disconnect attack of client. Additional Info: Avg-Deauth-Disassoc-PktRate(pps):1.4; Interval(sec):10. We use IDS default profile with IDS DoS default setting including enabled Detect Disconnect Station Attack. How best can we correct this situation?
