[Linuxptp-users] Need to disable Follow Up message

[Hari K. <hku...@gm...>]

Hi All,

I need to disable followUp messages in initial ptp stack messages in
Boundary clock mode.
I have disabled OneStep flag but the interface is not coming up with the
master. So, enabled the OneStep flag and all are working fine but I
dont want followUp messages since it is a Unicast profile.
Please help me to disable followUp messages in linux stack.

Regards,
Hari

You can disable announce messages with the inhibit_announce option.

But I guess you actually need to keep the unicast message and only
disable multicast messages, in which case there is the
inhibit_multicast_service option.

I should read the mail more carefully. There is no option to disable
followUp message on two-step clocks. That would prevent
synchronization.
