Create the sfptpd.service unit file as /etc/systemd/system/sfptpd.service:

[Unit]
Description=sfptpd
DefaultDependencies=true
Wants=network-online.target
After=network-online.target
[Service]
ExecStart=/usr/sbin/sfptpd -f/<path>/ptp_slave.cfg
[Install]
WantedBy=multi-user.target

The above example ensures that sfptpd is not started until the network-online.target is available to ensure that all network interfaces are configured and in an ‘up’ state before sfptpd is started. The sfptpd interface can be specified in the ptp_slave.cfg file.

Note: You should be aware of the following:

The full path is required to the sfptpd config file.
The sfptpd interface must be configured with an IP address and must be in an up state before sfptpd can be run.
Run systemctl daemon-reload after changes are made to the unit file.
