Disable and remove certain lines

Last Updated: Mar 20, 2018

This document describes how to disable or remove a resolution line for the origins that use CNAME to access Anti-DDoS Pro.

Disable a line

Note: This operation is only applicable to the origins that use CNAME to access Anti-DDoS Pro.

Follow these steps to disable a line:

  1. Log on to the Alibaba Cloud Security Anti-DDoS console.
  1. Go to Anti-DDoS Pro > Web Service.

  2. Locate the domain name to be configured, and click Origin Edit under the Domain Info of the target domain name.

  3. In the Anti-DDoS IP /Domain Resolution Switch column, you can enable/disable a target line by using the corresponding toggle button.

When a line is disabled, no inbound website traffic passes through this line.

Remove a line

Note: Before performing this operation, make sure that the website access traffic only passes through resolution lines that are enabled. If you are using a CNAME to access the Anti-DDoS Pro Web service, make sure that the line you want to delete is disabled first, which also means that the CNAME resolution is disabled.

Follow these steps to remove a line:

  1. Log on to the Alibaba Cloud Security Anti-DDoS console.

  2. Go to Anti-DDoS Pro > Web Service.

  3. Locate the domain name to be configured, and click Origin Edit under the Domain Info of the target domain name.

  4. Click Edit IP in the Operation column.

  5. On the Edit line page, click OFF under the target line to remove it, and then click OK.

    Note: Before removing a line, make sure that the website access traffic does not pass through this line.
