#25: How to Set Up Software Defined Networking

Learn how to set up software defined networking with Antsle. 

Video Transcription:

Hi, everybody. It’s Bernie here. What's up you guys? I’m talking to you today from another sunny December day here in San Diego. Today we're talking about something really exciting, which is software defined networking — our latest feature in the Antsle, the private cloud stack. 

So let's get right into it. I have my Antsle up and running here. It's called Aster. I'm in the network setting here. You probably already have seen the network settings as they've been there for some time now. We have a few physical NICs here. We can enable them or disable them. You see all the network settings here. That's all standard. That's the physical network settings. We have a new column called trunking. So when you enabled trunking, you can have the vLAN tagging enabled on this physical NIC here.

That would mean we're letting only that traffic through that has a specific tag for a virtual LAN. So with that, you can use your physical infrastructure, like your switch or something that you've installed there and can use the same physical equipment for several virtual software defined LANs. You will understand more what the trunking actually is when I've taken you through the SDN tab. That's the new tab — software defined networking.

 So let's look what's behind this. You see, we can define virtual LANs here. Virtual LANs are completely isolated. We can just create a new one. So, let's give it a name, like “mynew” and let's give it a tag. For example, let’s use “17” for the tag which happens to be my birthday. Alrighty. So now the virtual network has been created successfully and I can assign a few antlets to it.

Let's pick these three and then connect these new antlets to the newly created virtual LAN. So, it's being created and now it's right here. We see the “mynew” and we see the three antlets here. Anyone can set up and create LANS in a super simple way. You can now see the tag that we assigned. 

We can also do traffic mirroring. You would use that, for example, to install wire shark in one of your antlets, or to do sniffing on your traffic to get some analytics. You can create the mirroring and indicate the network of your choice in the “Source VLAN” field. In our example, we’ll use “first network” which is all of my traffic. I want that traffic to be mirrored to the “mynew” network. We can then enable it from the start and save that configuration. We have the mirroring available are are able to edit everything or delete it if we choose. It’s that easy to use. 

So now we see those two vLAN tags here. Again, if you go back to the physical network settings and enable the trunking here, then we will only receive traffic on that physical interface here if we have some tags for it. On the flip side, if we don't have it, we don't get or receive it. We'll leave it for other physical devices that are connected to your network. 

So that's basically it. It was a pretty short tour. Don't forget to smash the like button cause it really helps the YouTube algorithm and it advances our movement (that's really what we all want!). Please leave any comments, tell me what you're thinking about, whether you need any additional functionality, or what use case you have in mind for the software defined networking. Okay. I hope you enjoyed this little video. Talk to you soon and see you in the comments. Bye.
