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 <name> <IP> <serviceType> <port>
-  show service [<name>]

Example:

add service Service-DNS-1 10.102.29.41 DNS 53
show service Service-DNS-1
        Service-DNS-1 (10.102.29.41:53) - DNS
