This section describes how to specify the limit for when a SmartNIC is in PTP synchronization.

PTP in-synchronization limit

The TimeSyncPTPInSyncLimit parameter specifies the range in ns in which a SmartNIC is considered to be in PTP synchronization. The NtTimeSyncGlobalStatus parameter in the information stream shows the status. An event is generated when the status changes.

Select a value for TimeSyncPTPInSyncLimit according to the expected and acceptable stability of the reference.
