The s0, s1, s2 strings indicate the different clock servo states: s0 is unlocked, s1 is clock step and s2 is locked. Once the servo is in the locked state (s2), the clock will not be stepped (only slowly adjusted) unless the pi_offset_const option is set to a positive value in the configuration file (described in the ptp4l(8) man page). The ptp4l program can be started from the command line or it can be started as a service. When running as a service, options are specified in the /etc/sysconfig/ptp4l file. Options required for use both by the service and on the command line should be specified in the /etc/ptp4l.conf file.Jun 10, 2021 · 第20章 ptp4l を使用した PTP の設定 Red Hat Enterprise Linux 7 | Red Hat Customer Portal; vSphere 7 での PTP サポート. vSphere 7 では PTP に関連する新機能として以下の2つの機能が追加されています。 ESXi のシステム時刻の PTP による同期 See The Linux PTP Project for more details about linuxptp in general and ptp4l(8) - Linux man page about ptp4l configurations in particular.
