Use the Configuration type page to choose which API to configure: libpcap or NTAPI.

The Configuration type page

The upper area displays the available SmartNICs and the port numbering. See SmartNICs and Port Speeds.

In the middle area, you select one of two configuration types:
  • LibPCAP setup - For apps using LIBPCAP

  • NTPL setup - For apps using NTAPI

Configuration type screen

The setup_wizard tool stores separate configurations for libpcap and NTAPI in an internal configuration file. To switch between the libpcap and the NTAPI configuration, select the configuration type and press S to save and exit.

LIBPCAP setup - For apps using libpcap

For use with applications that support libpcap. When you save this configuration, the driver configuration file /opt/napatech3/config/ntservice.ini is modified and the libpcap configuration file /opt/napatech3/config/ntpcap.ini is created.

NTPL setup - For apps using NTAPI

For use with applications that support the Napatech API (NTAPI). When you save this configuration, the driver configuration file /opt/napatech3/config/ntservice.ini is modified and an NTPL configuration file /opt/napatech3/config/default.ntpl is created.

A system key ntplFileName in ntservice.iniis set to the name of the NTPL configuration file, and the NTPL configuration file runs automatically when the driver is started.

Tip:

Delete the key ntplFileName if you do not want the NTPL configuration file to run.
