Configuring Flood Attack Detection

Configuring Flood Attack Detection


If a large number of broadcast packets are sent to a device in a short time, the device becomes busy processing the packets and cannot process normal services. To prevent flood attacks, you can configure flood detection and a STA rate threshold. If the STA rate exceeds the threshold, the device considers that the STA is launching a flood attack by sending broadcast packets. The device will discard excess packets to ensure network security.


  1. Run:


    The system view is displayed.

  2. Run:


    The WLAN view is displayed.

  3. Run:

    vap-profile name profile-name

    The VAP profile view is displayed.

  4. Configure flood attack detection.

    • Configure broadcast flood attack detection.
      1. Run the undo anti-attack broadcast-flood disable command to enable flood attack detection.

        By default, the broadcast flood detection function is enabled.

      2. Run the anti-attack broadcast-flood sta-rate-threshold sta-rate-threshold command to set the rate threshold for broadcast flood attack detection.

        By default, the broadcast flood threshold is 10 pps.

      3. (Optional) Run the anti-attack broadcast-flood blacklist enable command to enable the broadcast flood blacklist function. The device then adds STAs that launch broadcast flood attacks to the blacklist.

        By default, the broadcast flood blacklist function is disabled.
