If phc2sys was only responsible for synchronizing the system clock to the PHC, using BMCA to turn it or off would make sense to me. > master -> synchronize all PHC master ports to clock_realtime This case would need to be handled by ptp4l. If phc2sys is doing that, i.e. it needs a management message to get information about ports of the PHC, I don't see how announce messages help. -- Miroslav Lichvar _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
