Why don't support 100% traffic performance with N3000 PAC Board?

I did a traffic​ performance test with N3000 PAC Board. but, the result of 100% performance were not confirmed. My test environment setup is as follows. 1. ​FPGA Source Version: Factory_Image in A...

Hi @SYeon​ Thank for the detail explanation of the issue.

The reason for packet loss is the you created a design that loops traffic directly from the Ethernet AVST interface AND is sending packets with minimum interframe gap. There is a rate difference between the Spirent Test Center Ethernet traffic generator and the N3000 internal clock. Because of this rate difference, there will be a small amount of packets dropped.

Setting the interframe gap to 13 bytes, will result in no packet drops.
