ptp system-time { get | set } ptp tc-internal [ mode <mode> ] <0-3>: Clock instance [0-3] ext:
Update the 1PPS and External clock output configuration and vcxo frequency rate adjustment option
ho-spec: Set the Holdover specification for G8275 PTP clocks system-time: Enable synchronization between PTP time and system time tc-internal: Define the internal mode used in TC's. Example: Input: 0* (config)# ptp 0 ? Output: Clk Sync: Set PTP slave clock options.
<1-1000>: [1..1000] Threshold in ns for offsetFromMaster defines when the offset increment/decrement mode is entered.
Domain:
Clock domain for PTP. <0-127>: PTP domain: range = 0-127.
Filter:
Set filter parameters: delay:
Set delay filter parameter. <0-6>: Log2 of timeconstant in delay lowpass filter, valid range: 1-6, Setting the value to 0 means use the same filter function as for the offset measurement, in this case the delay filter uses the 'period' and 'dist' parameters. Set offset filter dist parameter. <0-10>: Distance between servo update n number of measurement periods, valid range: 0-10, 0 => 0,1 Hz lowpass filtering, 1 => averaging over period, >1 => 'min' offset filtering.
dist:
filter-type: Define offset filter type: basic: Basic offset filter. ms-pdv: MS-PDV.
