Configuring PTP Globally

Context

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.

Procedure

Run system-view
The system view is displayed.
Run ptp enable
PTP is enabled globally.

By default, PTP is not enabled globally.
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.
(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.
(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.
(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.
