AFM Online Help was not updated after 11.4.0 to reflect a change in behavior. Prior to 11.4.0 the DoS Detection Threshold Percentage function would drop packets if an attack was detected. This was regarded as unintuitive when there was a separate rate-limit configuration element that customers could use to drop traffic when an attack was detected.
Inaccurate description of feature behavior.
Anyone referring to OLH for a DoS vector Threshold Percentage Increase.
Disregard erroneous information in OLH.
AFM Online Help has been updated to reflect a change in behavior in the DoS Detection Threshold Percentage. After 11.4.0 the DoS Detection Threshold Percentage function no longer drops packets if an attack was detected. OLH now reflects this.
