Direct Capture Mode - ProfiTap PROFISHARK 1G User Manual

Direct Capture Mode

ProfiShark 1G provides with the option to capture traffic
without the need for third-party capture software. This mode
of capture is performed on a driver level, prior to all network
stacks and frame processing. With the support of direct
capture, small packet capture can be performed at wire speed.
The capture file is saved in PCAP Next Generation format
(.pcapng).
The packet timestamps are hardware generated with 8
nanosecond accuracy. The direct capture feature is compatible
with the different hardware features: "Packet Slicing",
"Transmit CRC errors", "Keep CRC32", "Disable Port" (see
"Features" chapter).
