Modify a CNAME record for Traffic Scheduler

After you add a scheduling rule in Traffic Scheduler, you must update the CNAME record for your domain name to direct traffic to Traffic Scheduler and activate the rule. This example uses a domain name hosted on Alibaba Cloud DNS.

Prerequisites

You have added a scheduling rule in Traffic Scheduler. For more information, see Traffic Scheduler overview.

Background

When you add a scheduling rule, Traffic Scheduler generates a CNAME address for that rule. You must update the CNAME record for your domain name to point to this address so that traffic is directed to Traffic Scheduler.

The following procedure uses a domain name hosted on Alibaba Cloud DNS as an example. The steps may vary if you use a different DNS provider.
