Changing a Backend Server Group

Scenario

This section describes how you can change the default backend server group configured for a listener.

TCP or UDP listeners forward requests to the default backend server groups.

HTTP or HTTPS listeners forward requests based on the priorities of the forwarding policies. If you do not add a forwarding policy, the listener will route the requests to the default backend server group.

Notes and Constraints

• The backend server group cannot be changed if redirection is enabled.
• The backend protocol of the backend server group must match the frontend protocol of the listener. For details, see Table 4.
• You can only associate a backend server group that is not used by any listener with a shared load balancer.

Procedure

1. Go to the load balancer list page.
2. On the displayed page, locate the target load balancer and click its name.
3. On the Listeners tab, locate the target listener and click its name.
4. On the Summary tab, click Change Backend Server Group on the right of Default Backend Server Group area.
5. In the displayed dialog box, click the server group name box.
   Select a backend server group from the drop-down list or create a group.

   1. Click the name of the backend server group or enter the name in the search box to search for the target group.
   2. Click Create Backend Server Group. After the backend server group is created, click the refresh icon.
      

      The backend protocol of the new backend server group must match the frontend protocol of the listener.

6. Click OK.
