Comparison of features supported by a VDS switch version earlier to 7.0 and VDS version 7.0 or later (NSX-T Data Center enabled).

IPFIX and Port Mirroring

An NSX-T Data Center transport node prepared with a VDS switch supports IPFIX, port mirroring.

See Port Mirroring on a vSphere Distributed Switch.

See IPFIX Monitoring on a vSphere Distributed Switch.

SR-IOV support

SR-IOV is supported on a vSphere Distributed Switch but not on a NSX Virtual Distributed Switch.
