VID
VLAN Identifier used for tagging the VLAN packets.
PCP
Priority Code Point value used for PTP frames.
DSCP
DSCP value used when transmitting IPv4 encapsulated packets
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 values for the Time Source parameter are:
16 (0x10) ATOMIC_CLOCK
32 (0x20) GPS
48 (0x30) TERRESTRIAL_RADIO
64 (0x40) PTP
80 (0x50) NTP
96 (0x60) HAND_SET
144 (0x90) OTHER
160 (0xA0) INTERNAL_OSCILLATOR
Object Description
UtcOffset
In systems whose epoch is UTC, it is the offset between TAI and UTC
Valid
When true, the value of currentUtcOffset is valid
leap59
When true, this field indicates that last minute of the current UTC day has only 59
seconds.
leap61
When true, this field indicates that last minute of the current UTC day has 61
seconds.
Time Trac
True if the timescale and the value of currentUtcOffset are traceable to a primary
reference.
Freq Trac
True if the frequency determining the timescale is traceable to a primary reference.
ptp Time Scale
True if the clock timescale of the grandmaster clock and false otherwise.
Time Source
The source of time used by the grandmaster clock.
