So I decided to search for a better explanation and I hit to the “Free SDN and OpenFlow Introduction” course. Well, it’s quite difficult for me to understand what’s going on in this lecture. Davidi is demonstrating how it is possible to program a flow on a Open v Switch, by using two VM: one of them hosts OpenDayLight, while the other a Cisco SDN app, based on Mininet. The lecture block is called “GNS3, Docker, Open v Switch, SDN, OpenDayLight and OpenFlow”. Now I came to a point where a practical example of a SDN is given. Still a lot to do, even if the counter says I’ve completed 64% of the course. I keep on following David Bombal lectures, to finish GNS3 course. Questo articolo è stato pubblicato in GNS3, NetWorking, SDN e taggato come gns3, GNS3 academy, hpe van sdn, OpenDayLight, SDN il 13 Maggio 2021 da Adelmo GNS3 – Surprise! My goal is still to have a controller+app working, to show students what the potential of SDN is. In a forum I found an interesting post, stating that the FlowManager App has similar functions when used on RYU environment. Unfortunately there is no way to have a copy of “Northbound Networks” “Flow Maker Deluxe” app, which is extensively used by David Bombal in his videos. The OpenvSwitch in GNS3 – Data Path GNS3 OpenvSwitch port description. After loggin in the controller, you’ll be able to register your devices on the controller and see the topology. It will be ready to work in a few minutes, but you’ll have to use Firefox to access the 8443 port of the controller, due to Chrome security paranoid behaviour. The virtualbox appliance works like a charm.

Finding the product n HPE site can be boring, frustrating and time wasting, so please use this link! Download site for HPE VAN SDN Controller. Please notice it’s a pretty old piece of software, so do expect some troubles in the way it works.

By doing some Google search, it is still possibile to download the appliance for free testing.
Now, let’s go further! In the David Bombal videos, an HPE VNA SDN application is shown. Please notice how many information is it possible to acquire and a small section dealing with “tables” and “flows”. Using Yang-UI I managed to get some information from the OpenvSwitch in the topology. I feel little frustrated in having so many issues but I keep on trying! Reference Topology as per GNS3 course exercise. After some further efforts from my previous post, I finally manged to get some data from ODL controller.
