IIRC gPTP has time-aware bridges which are equivalent to PTP boundary clocks. ptp4l as a boundary clock doesn't require any special configuration. For a gPTP example see configs/gPTP.cfg in the linuxptp tarball/repository. If your interfaces don't share a PTP clock, you will need to enable the boundary_clock_jbod option and run phc2sys to keep the two PHCs synchronized. However, that might not meet the gPTP requirements on accuracy. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
