On the PTP master you could try this: ptp4l -m -i $ETH --clockClass 6 phc2sys -a -r -r -P 1e-4 -I 1e-8 The system clock should be synchronized, e.g. by NTP. The slaves can be configured by timemaster using both NTP and PTP. > Because weak PI servo, or the constants I should use are not exactly self > evident for a PTP beginner – and likewise for which algorithms will give the > most accuracy.

With good switches with PTP support jitter of 50 nanosecond might be possible. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
