Unable to monitor Cisco Nexus traffic

I am running SO on a VBox VM from a Windows host and I am spanning layer 2 traffic from a Cisco Nexus 9396 to a dedicated sniffer interface on the host.

SO does not detect anything coming in. tcpdump on the interface shows plenty of traffic but it is all seen as "Ethertype Unknown"
