2.5.4.1 Packet generator:

This setup configures the unit to emit a best effort packet stream on port 1. The rate of packet generation and the

data contained in the packets is configurable by the user.

The setup sets the FPGA packet aggregation delay to zero.

For the packet generator, a packet can be specified in hex. The format of the hex is as follows:

This represents the entire frame. Wireshark can be used to export packets as hex and paste the output to the packet

generator. This involves right-clicking a packet in a Wireshark capture and selecting the option to copy the

frameasraw binary.

The packet generator will re-calculate the Ethernet frame's CRC before sending it out. The frequency of sending the

packets is set using the input field for "Time between packets".
