Configuring the WSM using Device Manager

Configuring DNS query load balancing

Before configuring load balancing based on DNS queries, configure the WSM for server load balancing. See Configuring virtual server load balancing.

To configure load balancing based on DNS queries:

1. Enable DNS query load balancing for the DNS service (service 53). See Configuring services for a virtual server. Set the following parameter.

­	DNS Query Load Balancing = Enabled

­	Delayed Binding = Enabled

2. Specify the host name strings to be load balanced. See Defining a string for URL load balancing. For example, set the following parameters.

­	string = www.[abcdefg]*.com

­	string = www.[hijklm]*.com

­	string = www.[nopqrst]*.com

­	string = www.[uvwxyz]*.com

3. Configure the real server(s) to handle the host name string(s). See Configuring a real server for URL-based load balancing.
   
   

   Note: If you do not add a defined string (or add the defined string any), the server will handle any request.
