Pri2: Clock priority 2 [0..255] used by the BMC master select algorithm.
Local Prio: Priority [1..255] used in the 8275.1 BMCA.
Local Clock Current time: Show/update local clock data:
PTP Time: Shows the actual PTP time with nanosecond resolution.
Clock Adjustment Method: Shows the actual clock adjustment method. The method depends on the available
hardware.
Synchronize to System Clock: Activate this button to synchronize the System Clock to PTP Time.
Clock Current Data Set: The clock current data set is defined in the IEEE 1588 Standard. The current data set is
dynamic.
stpRm: Steps Removed; the number of PTP clocks traversed from the grandmaster to the local slave clock.
Offset From Master: Time difference between the master clock and the local slave clock, measured in ns.
Mean Path Delay: The mean propagation time for the link between the master and the local slave
Last GM Ph Change: The value is the phase change that occurred on the most recent change in either
grandmaster or gmTimeBaseIndicator.
Last GM FR Change: The value is the frequency change that occurred on the most recent change in either
grandmaster or gmTimeBaseIndicator.
GM time base: timeBaseIndicator of the current grandmaster.
GM change count: The number of times the grandmaster has changed in a gPTP domain.
Last GM Change Event: The system time when the most recent grandmaster change occurred.
Last GM Phase Change Event: The system time when the most recent change in grandmaster phase occurred
due to a change of either the grandmaster or grandmaster time base.
Last GM Freq Change Event: The system time when the most recent change in grandmaster frequency
occurred due to a change of either the grandmaster or grandmaster time base.
Clock Parent Data Set: The clock parent data set is defined in the IEEE 1588 standard. The parent data set is
dynamic.
Parent Port ID: Clock identity for the parent clock; if the local clock is not a slave, the value is the clocks own ID.
Port: Port Id for the parent master port.
PStat: Parents Stats (always false).
Var: It is observed parent offset scaled log variance
Rate: Observed Parent Clock Phase Change Rate (i.e. the slave clocks rate offset compared to the master
(unit = ns per s)).
Grand Master ID: Clock identity for the grand master clock, if the local clock is not a slave, the value is the clocks
own ID.
Grand Master Clock Quality: The clock quality announced by the grand master (See description of Clock Default
DataSet:Clock Quality).
Pri1: Clock priority 1 announced by the grand master.
Pri2: Clock priority 2 announced by the grand master.
