In NTP/PPS mode, sfptpd will get time-of-day from NTP, then use
the 1PPS signal to closely synchronize the adapter clock. All other clocks, including
the system clock, are synchronized to the adapter clock.
Note: It is a requirement to setup NTP
symmetric authentication to allow
sfptpd to control the local NTP
client.Note: Only a single NTP sync_module is required. Do not create multiple NTP sync modules.
For this mode, use the default pps_slave.cfg file:
- from the tarball package:
cd <install_dir> ./sfptpd -i <interface> -f config/pps_slave.cfg - from the binary RPM package:
cd /usr/share/doc/packages/sfptpd/ sfptpd -i <interface> -f config/pps_slave.cfg
where <interface> is the identifier of the timestamping port on the adapter.
