Hi Mike, That seemed to do the trick, thanks for info! At some point, can we make these steps part of the N32x getting started docs?
Also- the config utilty makes me choose 2x2x10 A, B, or LOM. Choosing A disables the second port on the QDA2, and B disables the first port. LOM disables both ports (expected because it's not a MB NIC). My ideal case is using 2x N321s over QSFP on the same XL710-QDA2 NIC. Have you had any luck in this configuration?
