FEXs arent switches. Think of them as cheap line cards for host connections. If you are staying in the cisco world buy multiple layer 2 n5500s or a 4510 with the appropriate line cards. You could get this to work by disabling spanning tree on the downstream switches, or just ensuring they dont send bpdus ( bpdu filter do this ?) - would i do it - no!
