Packet loss (transmission errors) 10/25gb ethernet subsystem (2.5)

Hello!

I work in Vivado 2018.3.

I am implementing an opto-electro-optical Converter based on KCU105 (2xSFP_OEO.jpg):

Settings  IP-core 10/25gb ethernet subsystem (2.5) - 10G_0.jpg, 10G_1.jpg, 10G_2.jpg:

10G_0.jpg10G_1.jpg10G_2.jpg

 

When testing on the XENA network (Ethernet traffic generation and analysis solutions for performance), I observe loss of ethernet packets, BER = x*10^-6 - x*10^-7:2xSFP_OEO — XENA.jpg

 

When generating and receiving ethernt traffic (broadcast) from a computer:

2xSFP_OEO — PC.jpg


Outgoing traffic > incoming traffic by 0.5 -1 %. Loss of some packages.

-------------------------------------------

Files of the project - TOP.vhdl, xxv_ethernet_csv_exdes.v.

 

I tried everything I could think of.
Packages are lost.
How can I solve this problem?

Hi @rotor.h1kobra 

Are you seeing any under run during the packet transfer. 

This can be verified with the below scenarios:

I do not understand.

I implemented the project from the example, turned off the generator and checker. 

Does not work as expected.

 Collect the project from my file and see for yourself.
