Hi Alvaro
The best way, if you are in OF1.3 is to split up things. Look at the
documentation regarding VLAN traffic. When I have VLAN traffic, I create a
specific table where I differentiate between non-tagged and tagged VLAN
traffic and if I need to get down to IP in VLAN traffic, I add an
additional table and pop the VLAN traffic before going to it.
Best, /PA
