    • 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.
