A DNS service is a representation, on the NetScaler 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.

To create a DNS service by using the command line interface

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>]
