Configuring UDP-based DNS Load Balancing
1. Configure and enable a virtual server IP address 1 on the switch.
2. Set up the DNS service for the virtual server, and add real server group 1.
3. Disable delayed binding.
Delayed binding is not required because UDP does not process session requests with a TCP
three-way handshake.
4. Enable UDP DNS queries.
5. Apply and save your configuration.
