The interactive setup_wizard tool walks you through the configuration and restarts ntservice when you save the configuration.


The setup wizard allows you to:
  • Map SmartNIC ports to libpcap interfaces and NTPL streams, merging and load-distributing traffic from the SmartNIC ports to the libpcap interfaces and NTPL streams.

  • Set up transmit capabilities for libpcap interfaces.

  • Select the algorithm used for load distribution. You can, for example, set up load distribution so that each data flow (traffic between a set of IP addresses) appears on one libpcap interface.

  • Change various settings such as synchronization.


You need privileges as root to run the setup_wizard tool.

Running the Setup Wizard tool

Start the setup_wizard tool from the command line:
sudo /opt/napatech3/bin/setup_wizard
setup_wizard attempts to start ntservice if it is not already started:
