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
The clock parent data set is defined in the IEEE 1588 standard. The parent data set is dynamic.
Object Description
• Parent Port Identity
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
• P Stat
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 Data Set: Clock Quality)
• Pri1
Clock priority 1 announced by the grand master
• Pri2
Clock priority 2 announced by the grand master
