<1> Can be `PtpConfigMaster.yaml` or `PtpConfigSlave.yaml` depending on your requirements. For configurations based on `{policy-prefix}group-du-sno-ranGen.yaml` or `{policy-prefix}group-du-3node-ranGen.yaml`, use `PtpConfigSlave.yaml`.
|
|
<2> Device specific interface name.
|
|
<3> You must append the `--summary_interval -4` value to `ptp4lOpts` in `.spec.sourceFiles.spec.profile` to enable PTP fast events.
|
|
<4> Required `phc2sysOpts` values. `-m` prints messages to `stdout`. The `linuxptp-daemon` `DaemonSet` parses the logs and generates Prometheus metrics.
|
|
<5> Optional. If the `ptpClockThreshold` stanza is not present, default values are used for the `ptpClockThreshold` fields. The stanza shows default `ptpClockThreshold` values. The `ptpClockThreshold` values configure how long after the PTP master clock is disconnected before PTP events are triggered. `holdOverTimeout` is the time value in seconds before the PTP clock event state changes to `FREERUN` when the PTP master clock is disconnected. The `maxOffsetThreshold` and `minOffsetThreshold` settings configure offset values in nanoseconds that compare against the values for `CLOCK_REALTIME` (`phc2sys`) or master offset (`ptp4l`). When the `ptp4l` or `phc2sys` offset value is outside this range, the PTP clock state is set to `FREERUN`. When the offset value is within this range, the PTP clock state is set to `LOCKED`.
