One-Way If true, one way measurements are used. This parameter applies only to a slave.
In one-way mode no delay measurements are performed, i.e. this is applicable
only if frequency synchronization is needed. The master always responds to
delay requests.
VLAN Tag Enable Enables the VLAN tagging for the PTP frames.
VID VLAN Identifier used for tagging the VLAN packets.
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 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
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 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
