Comment 8 for bug 1510475

Yes, that is correct, I was trying to show You how the structure looks like with these port-1:4 interfaces because they are physical.
Please let me know which commands will be good to see with link-up.

I connected to port-1 end point device (with VLAN_ID=0) and using tcpdump I didn't see anything that could be troubling, at this point.
Maybe you would like to see VLAN_ID=2 or 3? Please let me know because there are many things that can be examinate, but I don't know which of them will be helpful for you.

Again vif --list show similar output. (port-1 link-up vlan-id=0)
