Are you using the hybrid_e2e option? This is not an issue with the protocol. As I understand it, the kernel will normally not send or accept a unicast packet to itself over a real network interface. It has the loopback interface for that. One way to get around that is to use multiple network namespaces. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
