Usage Guidelines

Usage Scenario

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

After the flood attack detection function is enabled, a device 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 device considers that the user launches a flood attack. If the dynamic blacklist function is enabled, the user will be added to a dynamic blacklist. If the threshold is set to a small value, the device may incorrectly add authorized users to the dynamic blacklist, causing the users unable to go online.

Follow-up Procedure

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

Example

# Set the flood attack detection threshold to 350.
