Create a DNS service

A DNS service is a representation, on the Citrix ADC appliance, of a physical DNS server in the network. A DNS load balancing virtual server sends DNS requests to the DNS server in the network through such a service.

Create a DNS service by using the CLI

At the command line, type the following commands to create a DNS service and verify the configuration :

- add service     - show service [] 

Example:
