I want to bring up 40G interface between two nexus 3064 over the fiber but it's not coming up. Have configured the switch for 48*10G and 4*40G. I'm using QSFP on both the switches, OM3 straight fiber cable with MPO connector. The interfaces are not coming up. Notably, it comes up with Coax 3M cable. So it's fine with coax but not with fiber. Will appreciate any help. Thanks.

Since you are using OM3 fiber, are your 40Gig optics Multimode?
