Hi Miroslav,

Please find the below inline:

Ok, so there is a gPTP bridge between ECU1 and ECU2. What do you see
in its announce messages? Is the grandmaster identity changing over
time?

*Ans: *No, The "grandmasterclockidentity"  is not changing, its always
contain the identity of the clock who is sending the announce packet.

The delay you had in the log was over 3 microseconds. Is the delay to
ECU1 the same and is it acceptable for the switch according to its
configured delay threshold?

*Ans : *We have kept pdelay threshold as 10000 in Netgear switch setting as
shown below .

->As shown in the ECU2 log we see the same delay (3+ microseconds) to ECU1

Thanks,
Raj
