Changing a Backend Server Group

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

TCP, TLS, and UDP listeners forward client requests to the default backend server group.

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

• 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.
• The backend server group of a dedicated load balancer can be associated with multiple listeners.
