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
The clock current data set is defined in the IEEE 1588 Standard. The current
data set is dynamic.
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.
Parent Port
Identity
Clock identity for the parent clock, if the local clock is not a slave, the value is
the clock’s own ID.
Port
Port Id for the parent master port.
PStat
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 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.
Clock Time
Properties Data
Set
The clock time properties data set is defined in the IEEE 1588 Standard. The
data set is both configurable and dynamic, i.e. the parameters can be
configured for a grandmaster. In a slave clock the parameters are overwritten
by the grandmasters timing properties. The parameters are not used in the
current PTP implementation. The valid Time Source values are:
16
(0x10) ATOMIC_CLOCK
32
(0x20) GPS
