Hi all,
I have Cisco Nexus 9xxx switch and 100G SR4 QSFP AOC breakout module. I want to do BERT test at each of the 4 lanes so I want to tell the switch to set the QSFP in loopback mode (whatever comes in the RX goes out in TX) then I have 25G BERT with a SFP+ module that I launch into the RX legs of the QSFP and check the error rate coming out of the TX legs.
I wonder if any of you can show me what I need to do after config t to set the QSFP to loopback?
Thank you
