[Linuxptp-users] ptp noob

[Cyril B. <cyr...@gm...>]

I develop a GigE Vision application (jiguiviou on gitorious)
GigE Vision 2.0 supports the dating of images PtP.
I have a master clock (MEINBERG lantime m600) and a switch PtP RUGGEDCOM
RSG2288.
Unfortunately, the switch does not support jumbo frame, required for very
high bitrates (near 850 Mb/s).
My PC has 5 NIC Intel I210.
My idea is to connect a NIC to the switch PtP, and GigE camera on a
different NIC.
enp1s0 -> PtP switch (Master Clock)
enp2s0 -> GigE camera (AVT Prosilica GT PtP client)

# ptp4l -A -m -i enp1s0 &
# phc2sys enp1s0-s-c-m-enp2s0 w &

a sample of what I get

# ptp4l: master s2 offset 60 freq 7000 path delay 7714
# phc2sys: offset phc 12 s2 path delay freq 11900 12960

Is this the right way?

Sorry for my english (google translate)

This looks okay.

This command line looks wrong.

Show us a longer sample of the output.

Thanks,
