Thank you for you answer!
When I run $ sudo tcpdump | grep ‘ptp’ it does return a lot of the following
two messages (repeatedly):
15:17:55.746473 IP 10.0.0.218.ptp-event > ptp-primary.mcast.net.ptp-event: UDP,
length 44
15:17:55.746504 IP 10.0.0.218.ptp-general > ptp-primary.mcast.net.ptp-general:
UDP, length 44
15:17:55.784460 IP 10.100.0.1.ptp-event > ptp-primary.mcast.net.ptp-event: UDP,
length 44
When running the command $ sudo ptp4l -H -i eno1 -s -m it returns the following:
ptp4l[9820.775]: selected /dev/ptp0 as PTP clock
ptp4l[9820.776]: port 1: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[9820.777]: port 0: INITIALIZING to LISTENING on INIT_COMPLETE
ptp4l[9828.219]: selected best master clock 3c5282.fffe.5abe30
ptp4l[9834.262]: selected best master clock 3c5282.fffe.5abe30
ptp4l[9842.064]: selected best master clock 3c5282.fffe.5abe30
ptp4l[9848.472]: selected best master clock 3c5282.fffe.5abe30
Kind regards,
