ptp_master_freerun.cfg - ptp_master_freerun.cfg - UG1602

This file shows how to configure sfptpd to act as a PTP master, using the NIC clock as the reference:

• A Freerun sync module is instantiated using the sync_module option.
• A PTP sync module is instantiated using the sync_module option.
• The PTP sync module is configured to act as a PTP master by using the ptp_mode option.
• The master also has ptp_tx_latency and ptp_rx_latency options that can be used to compensate for latency between the clock and interface (see PPS Measurements).
