[ovs-discuss] Open vSwitch openflow example

Your question is somewhat vague.  But for what it is worth, to provide 
an idea of what can be done, this is an extract from a bash script which 
maps the flows in each direction from one vlan on one port to another 
vlan on another port.

VLANA=$(ovs-vsctl get Interface {{ mapping.a.port }} ofport)
VLANZ=$(ovs-vsctl get Interface {{ mapping.z.port }} ofport)
ovs-ofctl add-flow {{ bridge.name }} 
priority=100,in_port=${VLANA},dl_vlan={{ mapping.a.vlan 
}},actions=mod_vlan_vid:{{ mapping.z.vlan }},output:${VLANZ}
ovs-ofctl add-flow {{ bridge.name }} 
priority=100,in_port=${VLANZ},dl_vlan={{ mapping.z.vlan 
}},actions=mod_vlan_vid:{{ mapping.a.vlan }},output:${VLANA}

But you mention you have an open flow controller, which may inject flows 
directly via the control channel.

If you would like more assistance, please let me know directly.
