[Linuxptp-users] Not able to observer SYNC, FOLLOW UP and ANNOUNCE packets in wireshark

[Aditya V. <adi...@5g...>]

Hi,
I cloned the master branch from https://github.com/openil/linuxptp
I ran the ptp application using sudo ./ptp4l -f configs/default.cfg -i
enp33s0 -2 -S -m. When I open the wireshark I am not able to observe sync,
follow_up and announce packets going from the application.

The output of uname -arn is
Linux amdserver 5.4.170-rt68 #1 SMP PREEMPT_RT Tue Jan 18 13:29:21 IST 2022
x86_64 x86_64 x86_64 GNU/Linux

But,

The same ptp4l code, with kernel 3.10 and RT patch with the same network
driver and hardware works fine. i.e. I am able to observe sync, follow_up,
announce, delay_request and delay_response packets in wireshark.

Can you please let me know how to resolve this issue?
let me know if I have to provide any further information.

Thanks and regards,
Aditya.
