I am trying to attach two identical baremetal linux servers with Mullanox 40Gig cards to ACI fabric. One to Leaf103 and another to Leaf104. Both Leaves are C9336C-FX2. I am getting no light on the switch interfaces or on the NICs. LED on the leaves change from amber to off, never go green. ACI throws a fault F0532: "Port is down, reason being notconnect, used by EPG on node 103." Same for node 104. I can take the same QSFP DAC cable and connect it across the two servers and Mullanox cards come up fine. Anything special I need to do for 40G Leaf Access port policy group? Tried it on ACI using 40G and with Auto.
