That doesn't look too bad. > Is there a way to improve the configuration?

It depends on the hardware. What NIC do you have? One thing you can try is to shorten the sync interval and decrease the PI constants, also on the client's port of the server to minimize the frequency noise transferred to the client. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
