Usage Guidelines

Usage Scenario

A flood attack occurs when an AP receives a large number of packets of the same type within a short period. As a result, the AP is flooded by too many attack packets to process service packets from authorized wireless terminals.

After the flood attack detection function is enabled, an AP counts the number of packets of the same type that it receives from a user at regular intervals. When the number exceeds a specified threshold, the AP considers that the user launches a flood attack. If the dynamic blacklist function is enabled, the user will be added to a dynamic blacklist.

Follow-up Procedure

Run the dynamic-blacklist enable command to enable the dynamic blacklist function.

Example

# Set the flood attack detection interval to 120s.
