Local retransmission and line loopback enables frames received on a network port to be retransmitted without involving the host CPU.

In this chapter

This chapter describes the local retransmission and the line loopback functionality:
  • Local retransmission enables frames received on one or more network ports to be retransmitted to one network port on the same SmartNIC without involving the host CPU.
  • Local retransmission with embedded time stamp appends a high-precision time stamp from the capture port to retransmitted frames, enabling load distribution to time stamp critical applications downlink.
  • Line loopback enables frames received on a network port to be retransmitted to the same network port without involving the host CPU.
