• PCP
Priority Code Point value used for PTP frames.
Clock Current Data Set
Object Description
• stpRm
Steps Removed: It is 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
Clock Parent Data Set
Object Description
• Parent Port Identity
Clock identity for the parent clock -- If the local clock is not a slave, the value will
be the clock’s own ID.
• Port
Port ID for the parent master port
• P Stat
Parents Stats (always false).
• Var
It is observed parent offset scaled log variance
• Change Rate
Observed Parent Clock Phase Change Rate. i.e. the slave clocks rate offset
compared to the master. (unit = ns per s).
• Grand Master Identity
Clock identity for the grand master clock -- If the local clock is not a slave, the
value will be the clock’s 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
Servo Parameters
Object Description
• Display
If true, then Offset From Master, MeanPathDelay and clockAdjustment are
logged on the debug terminal
• P-enable
If true, the P part of the algorithm is included
• I-enable
If true, the I part of the algorithm is included
• D-enable
If true, the D part of the algorithm is included
‘P’ constant [1..1000] see above
