In this chapter

Napatech SmartNICs can automatically switch between time references according to a configurable prioritized list. When a time reference is lost, the SmartNIC fails over to the next available reference in the list. This chapter describes examples of typical time reference priority and failover configurations.

ntservice.ini code lines are included for reference. Time-Stamping and Time Synchronization Configuration describes configuration in general.
Note: PTP time synchronization does not apply to the following SmartNICs.
  • NT50B01
  • NT40A11
  • The Intel® Programmable Acceleration Card with Intel® Arria® 10 GX FPGA running Napatech Link-Capture™ Software
