Hi, Just upgraded to v4.0, and trying the new feature of 'phc2sys' with multiple '-c'.
It seems not working very well on my test machine, with large offset jitters. Here's my configuration: 1) ptp0~ptp3 are 4 ports on a 4 port i350, ptp4~ptp9 are separated i210 ports. 2) run ts2phc on ptp3(enp1s0f3), to sync ptp3's phc with external 1pps 3) run phc2sys to sync other phcs with ptp3: phc2sys -s /dev/ptp3 -c /dev/ptp2 -c /dev/ptp1 -c /dev/ptp0 -O 0 -f /etc/linuxptp/phc2sys.conf -l 7 -N 10 phc2sys[496846.875]: /dev/ptp0 phc offset -5 s2 freq +117755 delay 10782

hundreds of nanoseconds, the last one in the command line which is polled first every time, eg ptp0 here, is stable. I have done a lot of tests, it's only related to the position the dest phc appended to the dest list. 4) running multiple phc2sys instance, each instance with only one sink, it works well as expected.

the 4 ports on the same nic, any combination of ptp0~ptp9 results the same. Have gone through the phc2sys codes, find nothing reasonable that explains this issue so far. I can see when the large jitter happens, the measured delay also varies a lot, perhapse it's related to the pcie tranfication process? _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
