This Link™ Capture Software v12.5.4 is a maintenance release in the 12.5 release series, addressing an issue related to Hot Swap of pluggables during Tx in the 1/10G and 10/25G FPGA images on NT50B01, NT100A01 and NT200A02 as well as an issue related to Rx potentially getting stalled on 1/10G and 10/25G FPGA images on NT100A01 when disconnecting and reconnecting the fiber.

Additionally, an issue related to potential CRC errors in the NT100A01 Flow-Manager FPGA-images has been fixed.

Other minor Software fixes and extensions included as well.

Please see release notes for further information.

The Napatech Link Capture 12.5 software release introduces these features:

    NT100A01:
        Support for 4x1/10G with Capture Flow Management feature set (new FPGA image: 200-9559)
        Support for 4x10/25G with Capture Flow Management feature set (new FPGA image: 200-9553)
    NT50B01:
        Support for 2x10/25G with Capture Replay feature set (new FPGA image: 200-9541)
    NT200A02:
        Support for Packet Slicing combined with Local Retransmit (port to port forwarding) on 2x40G and 2x100G with Capture Replay feature set

Please refer to the documentation and release notes for details on the new features, bugfix’es and which SmartNIC products the new features apply to.
