Configuring PTP Globally
Context
In certain scenarios, a device may need to transmit multi-channel clock signals without needing to synchronize with multiple clock sources. You can configure the device as a transparent clock (TC), which then transmits clock signals and measures
the link delay without needing to synchronize with the clock signals.
Procedure
- Run system-view
The system view is displayed.
- Run ptp enable
PTP is enabled globally.
By default, PTP is not enabled globally on a device. - Run ptp device-type { e2etc | e2etcoc | p2ptc | p2ptcoc } slot slot-id
The PTP device type is configured as TC.
By default, no device type is configured for a PTP device.
End to end transparent clock and ordinary clock (E2ETCOC) is a transparent ordinary clock that supports only the end-to-end delay mechanism. Peer to peer transparent clock and ordinary clock (P2PTCOC) is a transparent ordinary clock that supports only the peer-to-peer delay mechanism. TCOC is a special TC that functions as an ordinary TC in terms of time synchronization but can recover the frequency based on PTP messages to synchronize with the upstream device. - (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 set for the device.
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 also 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.
