Hallo Richard,

Thank you for your answer ... As a matter of fact,  when my colleague has
ask me that i also said that it does not make sens :-) and we would need
separate port and PHC :-) ..

I clear is our situation :

the purpose will be used on embedded software on train .

the train  has two railway engine, one on the front and the other on the
back. these two engines run a ptpd daemon as a master. both  engine
communicate independently with an I/O board controller which would run a
ptpd  daemon as a slave.


so my idea is to have two ptpd daemon as slave on the I/O board
controller . One of the slave daemon will communicate with the front master
and the other will communicate  with the other master at  back of the train.

I read about configuring domain. How could I use this idea.

Once again thank you for all,
Baya
