Hi, I'm trying to do something similar but slightly different than Vadim on this thread https://sourceforge.net/p/linuxptp/mailman/message/35980617/
I too have PTP ethernet cameras that need the full bandwidth of the nic. The difference is that I also have a PTP timeserver (timemachine's TM2000A). The host PC uses linuxptp with hardware timestamping. When I put the cameras on the same gig-e switch, it all plays nice and I get satisfying offsets (sub us). To put the cameras on their own nic, I must also put them on their own subnets, so I would need to route ptp traffic back'n'forth. Is that possible? Should I rather synch the cameras with my (synched) PC clock with, e.g. ptp4l -i if_cam0 -i if_cam1 -m -S (I noticed you can't use hardware timestamping with multiple interface for reasons that are probably obvious to you guys) If so, I may have not tried hard enough, but I could not get satisfying results with that methods (I have a litle setup that trigs cameras, and the returned timestamps were 10-100 ms appart) Thank you very much Maxime
