big thanks to you for providing all these great knowledge for free. quick question: which cisco switches support openflow? can we install openflow on any cisco switch? I got a "Cisco Catalyst 2960-CX 8 Port Data Lan Base" and was wondering how to enable openflow on it. thank you in advance.

Thanks Sir.

Thank you a lot !

Many Thanks once again for another very informative presentation David. I was wondering if we could Ubuntu Gui, instead of the Ubuntu docker container as to make things more permanent and follow the rest of the upcoming presentations. Please advise. Cheers....

It would be great if you add some videos related using SDN for mitigating attacks like running defense4all or OpenSec platform. There are not much documents regarding them. I am appreciated if you share links regarding OpenSec or other security platform in SDN Networks

Hi David, can you please be so kind and tell me what IP you set on the Windows VM as the default gateway (if any)? Also, is it possible for two hosts to communicate from different networks (VLANs) via this setup? Thanks in advance.

for those who may experience error: /usr/bin/env: ‘node’: No such file or directory , while executing grunt, please execute this command to create sym link: ln -s /usr/bin/nodejs /usr/bin/node

hi sir, after enabling this command " sudo apt-get install oracle-java8-installer oracle-java8-set-default" i am getting downloaded fail and 404 error, could you look at it, please

In this video, you are using Ubuntu docker (ODL installed in), but I am using the virtual machine inside VMware(it is not taking the IP address from nat cloud inside GNS3, but it is taking the IP address from VMnet adapter). I am also running two raspberry pi virtual machines(openvswitch installed inside them) as switches inside GNS3 from VMware, but those adapters also connected to VMnet, that's why when I am adding ethernet ports to ovs bridge, it's not functioning, so it will not respond also with ODL controller. So is there any way to configure ethernet ports(after GNS3 overwrites on VMnet adapters, let's say the virtual machine has 4 VMnet adapters and one of them I want that get to IP address from nat cloud) of virtual machines that it will take IP addresses from nat cloud? The main reason I want to do this because sometimes nat cloud is very slow. so I want some adapters to use VMnet IP address and some adapters use nat cloud IP addresses. THANK YOU.

Hello David, Thanks to explain this video. I stuck in this command "sudo apt-get install oracle-java8-installer oracle-java8-set-default". I am getting below error. "Package oracle-java8-installer is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'oracle-java8-installer' has no installation candidate E: Unable to locate package oracle-java8-set-default root@Ubuntu-1:~# " Can you help me on this?

Hello David and everyone. I have installed Opendaylight release Oxygen, and it is running well. But I have some issues installing OpenFlow Manager (OFM). I followed all the steps but in the end, I got this error Controller error Cannot load topology data from controller, check connection settings in config Cannot load inventory data from controller, check connection settings in config What might that be??

Can you kindly tell what alternate freeware switch can we use instead of CiscoIOSvL2 switch.

what do ubuntu-2 work?

I have a nice information about internetworking for I've built me own core network at home and administrate it, It looks like I have what corresponds CCNP Cert. In fact, I decided to take the CCNA and go up with Cisco Certifications. And since I am very good in python so what branch of Cisco Certifications you advise me to continue up with? I will be appreciative.

Hello, thanks for this great contribution. I have been banging my head to the wall in order to have opendaylight working. Ideally it would be under a VM pre configured. I am stuck with my installation, I get this: marcelo@sdn-linux:~/distribution-karaf-0.3.0-Lithium$ ./bin/karaf -bash: ./bin/karaf: No such file or directory I the text file, it is not clear when we installed karaf
