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. > Does OpenStack support SR-IOV VF vlan trunk? If yes, what kind of > configuration is needed? 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). -- James Denton Network Architect Rackspace Private Cloud james.den...@rackspace.com<mailto:james.den...@rackspace.com> From: "Xu, Rongjie (Nokia - CN/Hangzhou)" <rongjie...@nokia.com> Date: Thursday, April 27, 2017 at 12:31 AM To: "openstack@lists.openstack.org" <openstack@lists.openstack.org> Subject: [Openstack] [OpenStack]SRIOV VLAN Trunk Support Hi, Background: I am using 82599 SR-IOV function, and attach the VF (by OpenStack) to the VM. I want to send and receive VLAN tagged and untagged traffic inside VM, just like the VLAN trunk port on the switch. My question are: Does SR-IOV support VLAN trunk? If yes, what kind of configuration shall I do for PF and VF (VM)? Does OpenStack support SR-IOV VF vlan trunk? If yes, what kind of configuration is needed? I try to search in the Internet, does it need somehow configure `Packet Filtering and Replication` in PF and tag/untag VLAN inside VM? Currently I set up a SRIOV provider network, create a neutron network on top of that. And then create port on this network and attach this port to VM. For this, I see inside VM, there is a VLAN ID for this port (VF) by default, which is the provider VLAN ID. Best Regards Xu Rongjie (Max)
