Use the Tx capable interfaces page to allocate transmit buffers for libpcap interfaces.

The Tx Capable Interfaces page

TX capable interfaces screen
For each libpcap interface defined on the Interface configuration method page, you can allocate buffers and select which SmartNIC port to transmit on:
  • For each application or application thread that transmits through a libpcap interface, allocate one Tx buffer.

  • Allocate 0 Tx buffers to disable transmit capability on a libpcap interface.

You can add additional transmit-only libpcap interfaces and map them to SmartNIC Tx ports.


Add a transmit-only libpcap interface.


Delete a transmit-only libpcap interfaces that you have added. You cannot delete the libpcap interfaces defined on the Interface Configuration page.
