Hi Wanderson, You can consider to use TSE IP internal loopback feature to help isolate your issue debug. Refer to below link for TSE user guide doc https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_ethernet.pdf Chapter 4.1.9 - shown MAC local loopback guideline Chapter 4.2.8 - explain on PHY loopback guideline If you also encountered failure with TSE IP internal loopback test then maybe you didn't configure TSE IP correctly or you are not sending correct MAC packet data format to TSE MAC IP. Thanks. Regards, dlim
