Open vSwitch (OVS) Switch

Running an OVS Switch on Ubuntuu 16 outlined here:

  1. Request your topology via omni or GENI Portal. Current default image version is Ubuntu 16, which will change over time.
  1. On the node you plan to use as a switch run the following:
     sudo apt-get install openvswitch-switch -y 
    
  1. Once OVS is installed, a service script is created on your node:

/etc/systemd/system/multi-user.target.wants/openvswitch-switch.service. This allows you to stop and start the openvswitch server. Service is automatically started for you, to check it status:

sudo systemctl status openvswitch-switch
  1. A script geniovs.sh is available to the dataplane interface to the OVS bridge:
    wget https://raw.githubusercontent.com/GENI-NSF/geni-support/master/Utilities/geniovs.sh
    sh ./geniovs.sh
    

Your switch is now ready to use!


If you would like to skip the 4 steps above, and simple load a custom image that has the OVS service running with all dataplane interface on its bridge, then you can use the custom image below:

 <disk_image url="https://www.instageni.sox.net/image_metadata.php?uuid=06c6ff42-5aa4-11e7-9a2c-000000000000" name="urn:publicid:IDN+instageni.sox.net+image+ch-geni-net:OVSnonOF:0"/>

If you have the openvswitch service running and would like to add OpenFlow to the mix, simply execute the following:

  sudo ovs-vsctl set-fail-mode br0 secure
  sudo ovs-vsctl set-controller br0 tcp:<controller_ip>:6633
