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

OS in-synchronization limit

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

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

ntservice.ini code lines

The syntax for the ntservice.ini code lines specifying the limit for when a SmartNIC is in OS synchronization is:

'TimeSyncOSInSyncLimit' '=' ( '1000' | '2000' |  '3000' |  ... | '0xFFFFFFFF' )

Example:

TimeSyncOSInSyncLimit=7000
