The anti-ddos auto-defend traffic-policy enable command enables dynamic traffic limiting for traffic attack defense.
The undo anti-ddos auto-defend traffic-policy enable command disables dynamic traffic limiting for traffic attack defense.
By default, dynamic traffic limiting for traffic attack defense is disabled.
Traffic attacks may cause a large volume of traffic to be sent to the MPU CPU for processing, which overloads the MPU CPU and affects services.
Attack traffic is checked on the hardware chip. If the session packet rate or traffic rate reaches the specified threshold, a traffic limiting rule is delivered to the hardware chip. Then traffic limiting is performed on the attack traffic on the hardware chip, reducing the MPU CPU usage.
