Description (partial)

Symptom:
Nexus devices that are directly connected to a host via a port configured as a Private VLAN port and the Nexus is connected to another device via a 
Trunk Port.  In this configuration a 802.1q tagged packet that does not match the Private VLAN configuration may be passed to another device via the 
Trunk Port.  It is expected that this packet would be dropped.

Conditions:
Nexus devices running an affected version of NX-OS.
