1. Summary

This page is for checking the PTP clock information.

You can check the information only when the PTP function is enabled.

2. Top page

This is the top page for the PTP clock information.

2.1. Clock information of this unit

  • Displays the clock information of this unit.

  • Displays the following information when the PTP operation mode is transparent clock.

    • Clock Identity

      • The ID to identify the PTP clock.

    • Number Of Ports

    • Primary Domain

      • The PTP domain number to which this clock belongs.

  • Displays the following information when the PTP operation mode is boundary clock.

    • Two Step Flag

      • If the state is Yes, transmit time information of PTP message in two steps with Follow Up message.

    • Clock Identity

      • The ID to identify the PTP clock.

    • Number Of Ports

      • The number of PTP ports.

    • Clock Quality - Class

      • The value that indicates the clock quality class (Smaller value indicates a higher quality).

    • Clock Quality - Accuracy

      • The accuracy of the clock.

    • Clock Quality - Offset (log variance)

      • The indicator that indicates a variation of the clock time.

    • Priority1

      • The priority to be used when selecting as the grandmaster clock.

    • Priority2

      • The priority to be used when selecting as the grandmaster clock.

    • Domain Number

      • The PTP domain number.

    • TimeReceiver Only

      • If the state is Yes, operates only as the timeReceiver.

  • This information is not displayed when the PTP function is disabled.

2.2. Current clock state

  • Displays the current clock state of this unit.

  • Displays the following information when the PTP operation mode is boundary clock.

    • Steps Removed

      • The number of PTP clocks passed through to the grandmaster.

    • Offset From timeTransmitter

      • The difference with the higher clock.

    • Mean Path Delay

      • The average communication delay between the higher clock.

  • Pressing the image button will refresh the displayed content.

  • This information is not displayed when the PTP operation mode is transparent clock or the PTP function is disabled.

2.3. Master clock information synchronized with this unit
