As a PTP slave, sfptpd is receiving and sending PTP messages to
an upstream PTP master clock.
For this mode, use the default ptp_slave.cfg file:
- from tarball package:
cd <install_dir> ./sfptpd -i <interface> -f config/ptp_slave.cfg - from RPM package:
cd /usr/share/doc/packages/sfptpd/ sfptpd -i <interface> -f config/ptp_slave.cfg
where <interface> is the identifier of the timestamping port on the adapter.
