The Napatech Link Capture 12.6.3 software release introduces these features:

  • NT100A01:
    • Support for 4x1/10G with Capture Test and Measurement feature set (new FPGA image: 200-9560-44-10)
    • Support for 4x10/25G with Capture Test and Measurement feature set (new FPGA image: 200-9554-44-10)
  • NT200A02:
    • Support for these features for all FPGA images with Capture Replay feature set
      • Header stripping
      • Packet masking
      • Load balancing with VLAN insertion

For full information on the Load Balancing feature as well as the new NTPL Action command, please visit the Napatech Documentation Portal or the DN-0449 archive in the release package, which are in slightly newer revision compared to the version embedded in the driver itself.

Please note that Windows support for FPGA image 200-9541-35-05 has not yet been validated.

Please refer to the documentation and release notes for details on the new features, bug-fixes and which SmartNIC products the new features apply to
