WebJan 19, 2024 · Newer revisions of gPTP bring back the ability to use one-step timestamps. Lastly, gPTP requires peer-to-peer delay mechanisms and expects all devices to be syntonized, which means that they have a standard frequency base and that all clocks are running at the same rate. Figure 2. The differences between PTP and gPTP. WebThe file gPTP.cfg (available in configs folder of Linux PTP source) specified by the -f option contains the configuration options to required to run ptp4l in gPTP mode while the -i option specifies the network interface this instance of ptp4l is controlling. The --step_threshold is set so ptp4l converges faster when “time jumps” occur (more on this later).
