If you purchase an on-demand Anti-DDoS Origin instance and DDoS attacks are detected on your server in a data center, you can manually enable traffic rerouting to the instance. After the attacks stop, you can disable traffic rerouting to the instance.
- Log on to the Anti-DDoS console.
- In the upper-left corner of the top navigation bar, select a region.
- On the Assets page, click the Others tab.The Others tab lists the IP addresses of the on-demand Anti-DDoS Origin instances that you have purchased in the current region. If you have purchased on-demand instances in other regions or have not purchased any on-demand instances, no data is displayed on the Others tab.
- Find the on-demand instance for which you want to enable traffic rerouting and click
Start Redirection in the Operation column. In the message that appears, click OK.After you enable traffic rerouting to the on-demand instance, the instance enters the Redirecting state. This indicates that the system is rerouting the traffic destined for protected assets to mitigate DDoS attacks.
If you want to stop traffic rerouting to the on-demand instance, click Pause Redirection in the Operation column.Note After you click Pause Redirection, the system no longer reroutes the traffic destined for protected assets to your on-demand instance and does not mitigate DDoS attacks for your assets.
You can also enable the Automatic (NetFlow) mode to automatically reroute traffic to an on-demand instance. You can enable or disable traffic rerouting to an on-demand instance based on the NetFlow information of your servers in data centers and rules that you specified. For more information about how to enable the Automatic (NetFlow) mode, see Enable the Automatic (NetFlow) mode.
