This file shows how to configure sfptpd to act as a PTP boundary clock:
- Two PTP sync modules are instantiated using the
sync_moduleoption. - One instance is associated with a particular
interface, and is configured to act only as a PTP master by using theptp_modeoption. - The other instance is associated with a different
interface, and is configured to act as a PTP slave by using theptp_modeoption. - The slave also has
ptp_tx_latencyandptp_rx_latencyoptions that can be used to compensate for latency between the two interfaces (see PPS Measurements). - Any PTP traffic is transmitted using hybrid mode by using the
ptp_network_modeoption in the generic[ptp]section (see Hybrid Mode).
Note: Using the ptp_boundary.cfg,
sfptpd will operate as both master and slave simultaneously within the same or different PTP domains. This boundary clock mode is not intended to meet all the requirements of a boundary clock as specified in the IEEE-1588 specification.Note: When acting as a master clock,
sfptpd uses UTC time and not TAI time.
