sfptpd configuration file
option captures and displays all PTP packets sent/received by the
sfptpd process. This is different from
which captures packets sent/received at the adapter interface.
ptp_pkt_dump option is useful for:
- Checking that PTP packets are actually being sent/received by
sfptpd. (Counters for all messages types sent/received are accumulated in the /var/lib/sfptpd/stats-<clock id> files.)
- Debugging badly formatted PTP packets.
ptp_pkt_dump option enabled for extensive periods as
this produces a lot of additional data. This option should be
used for debug purposes only.
