The issue is with the order in your actions actions = [[openflow.OFPAT_OUTPUT, [0, output]], [openflow.OFPAT_SET_VLAN_VID, 2]]
Change it to this: actions = [ [openflow.OFPAT_SET_VLAN_VID, 2] ,[openflow.OFPAT_OUTPUT, [0, output]] ] and then it should work I think. Right now your flowmod first outputs the packet and then adds the tag. You need to switch the order.
