You can have multiple ptp4l instances talking to each other on a
single system, but you need to disable the loopback shortcut between
them. The easiest way to do that
Hi Miroslav,
I checked your patch and tried it, but in my setup, it's failing well
before the part of the code you have changed.
The function "*rtnl_iface_has_vclock*" determines whether the given clock
is VPHC which is failing and hence it exits during the Initialization phase
itself.

Hi, Miroslav:
Thank you for your reply!
but i didn't understand, on a single system, port 0 as master and port 1 as
slave, and there is cable connect port 0 and port 1 for pkt communication.
why ptp protocol doesn't work this way?
Thanks
Alex

Can you please run ptp4l in strace and post the output?

no, i am not using hybrid_e2e option.
just two port, port 0 as master and port 1 as slave (ordinary clock mode),
and they are connected with cable.
run ptp4l on port 0 and run another ptp4l on port 1, but port 0 didn't
send delay response message.
Thanks
Alex

Hi,
I have attached the strace log.
Thanks,
