Configuring the 1588v2 Synchronization Function on the Device Where an Atom GPS Module Houses

Configuring 1588v2 globally involves operations such as enabling 1588v2 in the system view and setting the device type to BC. After enabling 1588v2 in the system view, enable it in the interface view. In addition, specify the link delay measurement mechanism, asymmetric correction value, and timestamping mode for the interfaces.

Context

Perform the following steps on the BC:

Procedure

Run system-view
The system view is displayed.
Run ptp enable
1588v2 is enabled.
Run ptp device-type bc
The device type is set to BC.
(Optional) Run ptp domain domain-value
A clock domain is configured.

Devices in the same clock domain can exchange 1588v2 packets to synchronize time signal.
(Optional) Run ptp virtual-clock-id clock-id-value
A virtual clock ID is configured for the BC.
(Optional) Run ptp asymmetry-measure enable
Automatic asymmetry measurement is enabled for the BC on a 1588v2 ring network.
(Optional) Run ptp set-port-state enable
Manually specifying the 1588v2 interface status is enabled.
Run interface interface-type interface-number
The interface view is displayed.
(Optional) Run ptp port-state slave
Configures a 1588v2 interface to work in the Slave state. This interface keeps tracking time information.
Run ptp delay-mechanism delay
The delay request-response mechanism is configured.
Run ptp enable
1588v2 is enabled for the interface.
(Optional) Run ptp announce-drop enable
The interface is configured to discard Announce messages.

Devices exchange Announce messages to establish the synchronization hierarchy. If an interface is configured to discard Announce messages, the device cannot receive clock synchronization information from other devices through this interface.
(Optional) Run ptp clock-step one-step
The timestamping mode for 1588v2 packets is set to one-step.
(Optional) Run ptp passive-measure enable
Performance measurement is enabled for the interface in the passive state.
(Optional) Run ptp passive-measure alarm-threshold alarm-threshold-value
An alarm threshold of the offset (time difference between slave and master clocks) is configured for the interface in the passive state.
