Configuring PTP Globally

Procedure

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.
