Configuring the WSM using Device Manager

Domain name server load balancing

You can choose the service for domain name server (DNS) load balancing based on UDP and TCP DNS queries. This enables the WSM to send TCP DNS queries to one group of real servers and UDP DNS queries to another group of real servers. The requests are then load-balanced among the real servers in that group.

The following figure shows four real servers load balancing UDP and TCP queries between two groups.

Note: You can configure both UDP and TCP DNS queries for the same virtual server IP address.
