Create an internal port:

    $ ovs=vsctl add-port ovsbr0 vlan9 -- set \
      interface vlan9 type=internal
      

Display OVS databse contents:

    $ ovs-vsctl show
    3dc7f3e3-5872-47c0-ba6f-1cb12065f4d0
        Bridge "ovsbr0"
            Port "eth0"
                Interface "eth0"
            Port "vlan9"
                Interface "vlan9"
                    type: internal
            Port "ovsbr0"
                Interface "ovsbr0"
                    type: internal
            Port "vnet0"
                Interface "vnet0"
        ovs_version: "1.10.0"


Run dhclinet on the vlan9:

    $ dhclient vlan9 &

Check the IP:

    $ ifconfig eth0


****

To configure an already added port (above) as an access port:

    $ ovs-vsctl set port ovsbr0 tag=9

    $ ovs-vsctl show
    3dc7f3e3-5872-47c0-ba6f-1cb12065f4d0
        Bridge "ovsbr0"
            Port "eth0"
                Interface "eth0"
            Port "vlan9"
                Interface "vlan9"
                    type: internal
            Port "ovsbr0"
                tag: 9
                Interface "ovsbr0"
                    type: internal
        ovs_version: "1.10.0"


The above tagging is wrong ( we have to set it to vlan9), so first untag:

    $ ovs-vsctl clear port ovsbr0 tag


Add access port to vlan9:

    $ ovs-vsctl set port vlan9 tag=9

But..the above removes network connectivity. Clearing the port, brings the
networking back:

   $ ovs-vsctl clear port vlan9 tag
