avbcapture(1) General Commands Manual avbcapture(1)

avbcaptureAudio Video Bridging traffic capture tool.

avbcapture command <arguments>

The avbcapture executable is used for capture a PCAPNG file containing gPTP and AVTP stream packets.

The following options are available for the pcap command:

--interface bsd-name
The interface to capture traffic on. This option may be provided multiple times to capture simultaneously from multiple interfaces to the one file.
--output path
Specifies the path to the PCAPNG file to put all the captured traffic.
--ring
Use a ring of packets and only output to file when the capture is stopped.
--length num-packets
The number of packets to keep in the ring. Defaults to 2,561,000 if not specified.
--allow-tap
Allow the tool to tap the receive queue rather than adding a stream capture allowing capture on a live system. This could potentially cause performance issues resulting in packets being lost.
--force-tap
Force using the receive queue rather than adding a stream capture allowing capture on a live system. This could potentially cause performance issues resulting in packets being lost.
