Change the weight of a backend server

This topic describes how to change the weight of a backend server to adjust the proportion of requests sent to the backend server.

1. Log on to the Server Load Balancer console.
2. On the Server Load Balancers page, select the region of the target SLB instance.
3. Find the target SLB instance and click its instance ID.
4. Click the Default Server Group tab.
5. Move the pointer over the weight value of the target backend server and click the icon.
   
6. Change the weight and then click OK.
   A backend server (ECS instance or IDC server) with a higher weight receives more requests.

   Notice The weight value ranges from 0 to 100. If the weight of a backend server is set to 0, no requests are sent to the backend server.
