ptp_master_ntp.cfg - UG1602

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

• An NTP sync module is instantiated using the sync_module option:
  • The key-id and key-value are set for authenticating with NTP using the ntp_key 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 NTP daemon and interface (see PPS Measurements).
• Any PTP traffic is transmitted using hybrid mode by using the ptp_network_mode option in the generic [ptp] section (see Hybrid Mode).
