Re: [Linuxptp-users] Raw socket close issue

[ramesh t <ram...@ya...>]

Hello Miroslav Lichvar,

Please find the value of ptp config as per 8275.1 standards.

logAnnounceInterval     -3
announceReceiptTimeout  3

We can't increase beyond the above values.

regards,
Ramesh

Maybe some optimization could be implemented in the kernel to shorten
that time. I don't know why it takes so long. What is your
logAnnounceInterval and announceReceiptTimeout? Could they be
increased?
