How Will Anti-DDoS Be Triggered to Scrub Traffic?

Anti-DDoS scrubs traffic when detecting that the incoming traffic of an IP address exceeds the traffic cleaning threshold.

• When the service traffic reaches this threshold, Anti-DDoS intercepts only attack traffic.
• If the service traffic does not reach the threshold, Anti-DDoS will not intercept the traffic, regardless of whether it is attack traffic.

You can adjust the traffic cleaning threshold based on the actual service bandwidth. For details, see Configuring an Anti-DDoS Protection Policy.
