Configuring the DNCA Interface

When the DNCA software is installed and started, it is not yet ready to capture bidirectional traffic. After installing the Unica Discover DNCA software, you need to configure the network interface to capture bidirectional traffic.

If there is a load balancer deployed between the DNCA and the web server or you have multiple web servers operating under a single virtual IP (VIP), configure your DNCA network interface for transparent load balancing. For more information, see Configuring the DNCA Interface with Transparent Load Balancing.

If your web server deployment does not use a load balancer and does not operate under a single virtual IP (VIP), you can configure your DNCA network interface without transparent load balancing. For more information, see Configuring the DNCA Interface without Transparent Load Balancing.
