Description
NT SmartNICs can be connected to an IEEE 1588 PTP network and synchronize the time stamp clock to a PTP grandmaster.
Illustration
The figure shows an NT SmartNIC configured in PTP slave mode. The Napatech SmartNIC time
stamp clock (TS Clk) is synchronized to the PTP grandmaster reference clock (Ref
Clk).
Note: On NT200A02 and NT100A01 SmartNICs the
RJ45 port on the external time synchronization connector is replaced by a separate RJ45
time synchronization connector.
ntservice.ini configuration
These ntservice.ini code lines configure the NT SmartNIC (Napatech SmartNIC PTP Slave) for the setup in Illustration and to permanently run in PTP slave-only mode (clock class 255).
