The switch can also carry tagged vlan 2 and 3702. The openvswitch port is configured like this : add-port br0 eth4 trunk=[0,2,3702], to carry untagged traffic and to carry vlan tagged to the switch.

For my personnel information, what are the majors difference between now and 3.1 ? The way how vlan are handle ? Thank you. Regards, -- -- Benoit -- -- Benoit
