[Linuxptp-users] logAnnounceInterval Vs announceReceiptTimeout

[Chandra M. <sma...@al...>]

Hi Friends,

While running the ptp4l, I observe the errors due to Announce message timeouts. Could you clarify the following?


*         My understanding is that logAnnounceInterval (default 1 in every two seconds) is to be set up at the master and announceReceiptTimeout (default 3 messages before the last message reception) to be at the slave. Am I right?

*         I see more of these erros when I increase the packet frequency for Sync and DelayReq (say 512 packets per second). Are there any optimal values for the above for such high packet frequencies?

*         Message_interval option also seems to play a role in addition to the increased packet frequency. If I reduce the message_interval to a very less value such as -9 (i.,e., increase the message frequency), the errors due to announce message timeouts seem to increase. Is it expected? Are the optimal values for 'logAnnounceInterval & announceReceiptTimeout' helpful in this case?

Please share your experience with these options.

Thanking you in anticipation,
Regards,
Chandra
