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 . [image: image.png] ->As shown in the ECU2 log we see the same delay (3+ microseconds) to ECU1 Thanks, Raj On Mon, Sep 12, 2022 at 8:28 PM Miroslav Lichvar <mlich...@redhat.com> wrote: > On Mon, Sep 12, 2022 at 07:23:03PM +0530, Raj wrote: > > Yes, ECU1 sends Announce packet in every 2 sec , however the switch in > > between (NETGEAR GS724Tv4) sends Announce packet to ECU2 every 1 sec. > > > > I tried with "logAnnounceInterval 0" in both ECU1 & ECU2 and observed > the > > same issue as mentioned above. > > Ok, so there is a gPTP bridge between ECU1 and ECU2.
