Configuring PTP Globally

Configuring PTP Globally


In a PTP domain, a PTP device functioning as an OC can synchronize time with an upstream device or send time to a downstream device. To configure a PTP device as an OC, enable PTP globally on the device, configure the device type as OC, and perform OC configurations in the system view.


  1. Run system-view

    The system view is displayed.

  2. Run ptp enable

    PTP is enabled globally.

    By default, PTP is not enabled globally.

  3. Run ptp device-type oc slot slot-id

    The device type is configured as OC.

    By default, no device type is configured for a PTP device.

  4. (Optional) Run ptp slaveonly slot slot-id

    The OC is configured to work in slave-only mode.

    By default, an OC port can be a master or slave port. When a device functions as an OC to synchronize with other clocks, configure the device to work in slave-only mode. After the device is configured to work in slave-only mode, ports of the device are in slave state. This indicates that the device can only function as a slave clock to receive clock signals from other clocks but cannot function as a master clock to provide clock signals for other clocks.

  5. (Optional) Run ptp domain domain-value

    The PTP domain to which the device belongs is configured.

    By default, a PTP device belongs to domain 0.

    Devices that perform clock synchronization through PTP messages must belong to the same PTP domain.

  6. (Optional) Run ptp virtual-clock-id clock-id-value slot slot-id

    A virtual clock ID is configured for the device.

    Each device in a PTP domain has a virtual clock ID. By default, no virtual clock ID is configured for a PTP device, and the system generates a clock ID based on the MAC address of the device. You can configure a virtual clock ID to identify the device.


    When running the ptp virtual-clock-id command, ensure that the configured virtual clock ID is unique in the entire PTP domain.
