<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">> Does SR-IOV support VLAN trunk? If yes, what kind of configuration shall I do for PF and VF (VM)?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">My experience has been YES, it does. At a minimum, the switchport should be configured as a trunk. The VF can be configured with VLAN ID 0, which will allow tagging within the VM.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">VLAN filtering is the default (and only) behavior supported by Neutron as far as I know. Without modifying the code, you’d be limited to a single VLAN per VF (untagged within the VM).<o:p></o:p></span></p>
