PTP (IEEE1588)
HMG-838PT & HMG-838EPT Web Configuration 21-2
and the port is member of the VLAN.
VID: VLAN Identifier used for tagging the PTP frames.
PCP: Priority Code Point value used for PTP frames.
Click on the “Clock Instance number” to edit the Clock details.
Local Clock Current time: This shows and updates local clock data.
PTP Time: Shows the actual PTP time with nanosecond resolution.
Clock Adjustment Method: Shows the actual clock adjustment method. The method depends on the available
hardware.
Synchronize to System Clock: Click this button to synchronize the System Clock to PTP Time.
Ports Configuration: Click to edit the port data set for the ports assigned to this clock instance.
Clock Default Dataset: The clock default data set is defined in the IEEE 1588 Standard. It holds three groups of data:
the static members defined at clock creation time, the Dynamic members defined by the system, and the configurable
members which can be set here.
ClockId: This shows the instance id number (0~3).
Device Type: This shows the Type of the Clock Instance.
Step Flag: This shows True or False.
Ports: This shows the total number of physical ports in the node.
Clock Identity: This shows unique clock identifier.
Dom: Configure clock domain (0~127).
Clock Quality: The clock quality is determined by the system, and holds 3 parts: Clock Class, Clock Accuracy
and OffsetScaledLog Variance as defined in IEEE1588. The Clock Accuracy values are defined in IEEE1588 table
