The DNS Traffic Control works as an add-on feature for the DNS service in the NIOS appliance. In order to use it, install the DNS and DNS Traffic Control licenses on the appliance. You can add the DNS Traffic Control license only when you have installed the DNS license. After you add the license, the feature becomes available to you in Data Management
-> DNS -> Traffic Control.
The DNS Traffic Control feature starts, stops, or restarts with the DNS service. You may need to restart the DNS service after you make configuration changes. When you click Restart at the top of the screen, the DNS Traffic Control service takes some time to update the configuration and the status of LBDNs, pools and servers on the appliance. For more information about how to install licenses, see Managing Licenses.
The appliance creates a new role, DTC Admin, when you install the DNS Traffic Control license. For more information about how to define permissions, see About Admin Roles.
