Configure Time Synchronization via the Device Manager

From the Configure menu, choose PTP.
Once you choose a mode, you can edit the settings for each port. The parameters
depend on the selected mode. You can configure per-port PTP when the switch is
in Boundary mode or End-to-end Transparent mode.
Description
Choose one of the following:
• Boundary—Synchronizes all switch ports with the Grandmaster clock by using the IEEE 1588 V 2 Boundary clock mechanism.
• End-to-End Transparent—Calculates and adds the switch delay into the PTP packet by using the IEEE 1588 V2 End-to-End
Transparent clock mechanism. In this mode, all switch ports are PTP-enabled. In boundary mode, one or more switch ports can be
PTP-enabled. You can enable or disable PTP on a per-port basis.
• Forward (default)—Passes PTP packets through without interference.
The switch that is used to override the default criteria, such as clock quality or clock class, for the best master clock selection.
The switch that is used as a tie-breaker between two devices that are otherwise equally matched in the default criteria. For example, you
can give a specific switch priority over other identical switches. The range is from 0...255. A lower value takes precedence. The default is
128.
The clock source.
The accuracy in nanoseconds from the Grandmaster clock.
The number of the switch port, including port type (such as Fa for Fast Ethernet and Gi for Gigabit Ethernet), the base switch number (1),
and the specific port number. For example: Fa1/1 is Fast Ethernet port 1 on the base switch.
