Has anyone done any progress on this error?
I thought i had faulty 40g ports, but it turns out the link work perfectly using dac cables. I've tried 4 different xbr-00232 modules so far on both ports of two different switches and i get the same error every time. It seems highly unlikely to me that all 4 modules are broken and since the link work perfectly with the dac cable (even connecting to a mellanox sx6036) i doubt the port are fried either. Btw config is vanilla as per @fohdeesha guide, just installed latest firmware and removed stacking.
