PRBS for QSFP ports
Connect ports with Loopback cables and run the PRBS MAC and EXT Loopback tests.
● PRBS MAC level test nputool –i –t 2 or nputool --init --test 2
● PRBS EXT level test nputool –i –t 3 or nputool --init --test 3

PRBS for uplink ports
Connect the SFP+ ports with an external Loopback cable.
● PRBS MAC level test ./nputool –i –t 6
● PRBS EXT level test “./nputool –i –t 7
