Hi,
Can you capture in the Linux side in raw mode?
It does not seems that the Linux response get back to TRex probably due to a wrong 
destination MAC address, not sure why.

Another thing worth checking is doing the same in Stateless mode (from the Console using l3 command)
I assume we can reconstruct this.
BTW usually we are not using Linux as a DUT so we haven’t observed this however 
while doing The NGINX vs ASTF TRex we encountered some similar issues.

Thanks,
Hanoh

I will update additional info with regard to stateless mode with l3 (I need to figure out how to do it.)

Can you capture to pcap file? The L2 headers are missing. I’m interested to understand why TRex does not receive the response packets.

Hi Hanoh,
Please find pcap file (ARP Req/Reply) attached, and let me know if you have any problem with it.
Thanks and have a great day,
