Re: OT Nexus 7K - FEX topology

Hi Achal

Topology 11 is a non-vPC topology, since both NICs are actvie/active, it'll
cause Mac-flapping on 7K hence not a supported design. You must have a
virtual path such as VSS/vPC for active/active NIC configuration.

Topology 7 shows an equivalent topology between two separate 7K and vPC
enabled, hence that's a supported design. Although topology 12 is listed as
unsupported, it should technically work fine. Since its one single 7K box,
its not recommended from a support POV.
