HP VAN SDN with mininet using OF 1.3
Install and setup and run mininet with OF 1.3 switches on Ubuntu.
Use mininet 2.1.0 or newer, so Ubuntu 13.10, 14.04 or newer, see:
http://mininet.org/download/
Mininet 2.1.0 on Ubuntu 13.10: sudo apt-get install mininet
Mininet 2.0.0 on Ubuntu 13.04: sudo apt-get install mininet
Mininet 2.0.0 on Ubuntu 12.10: sudo apt-get install mininet/quantal-backports
Mininet 2.0.0 on Ubuntu 12.04: sudo apt-get install mininet/precise-backports
Using Ubuntu 14.04 Beta>
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.04 LTS
Release: 14.04
Codename: trusty
$ sudo apt-get install mininet
$ mn --version
2.1.0
The following links show starting mininet using the --switch ovsk,protocols=OpenFlow13 parameters:
https://wiki.opendaylight.org/view/Openflow_Protocol_Library:OpenVirtualSwitch
http://blog.disects.com/2014/01/ovs-ofctl-commands-on-openflow-13.html
$ sudo mn --controller=remote,ip=XXXXXXXX --topo linear,2 --switch ovsk,protocols=OpenFlow13
However, the HP VAN controller shows the mininet switches as OF 1.0.0.
Open a second terminal on mininet server and run ovs-vsctl commands for each switch, e.g.
$ sudo ovs-vsctl set bridge s1 protocols=OpenFlow10,OpenFlow13
$ sudo ovs-vsctl set bridge s2 protocols=OpenFlow10,OpenFlow13
I found this at the end of mininet + ryu git setup instructions at:
http://networkerjr.wordpress.com/2013/11/14/learning-switch-tutorial-on-ryu-ovs-2-0-of-1-3/
Do not need the to build mininet and ryu from git, just need the ovs-vsctl commands at the end of the instructions.
Took me a while to find this, hope this helps someone.
Dave.

Re: HP VAN SDN with mininet using OF 1.3
Dave,
I recently started working with SDN Controller. I was able to get SDN controller 2.2 installed on an Ubuntu 13.10 machine with mininet 2.1.
When I try to access SDN controller it gives me login prompt post which there is just a blank page. The URL of the blank page says http://<>:8443/sdu/ui/app/login
Would you be able to help me with some ideas on what might be wrong?
Appreciate your help.

Re: HP VAN SDN with mininet using OF 1.3
This is excellent. I was wondering why I was seeing OF 1.0 in the controller when using the latest mininet.
It was not letting program flows because the flows I was attempting were only supported by OF 1.3.
This definitely should be a KB document.

Re: HP VAN SDN with mininet using OF 1.3
Hello,
When I run the following command, I get error.
$ ovs-vsctl set bridge s1 protocols=OpenFlow10,OpenFlow13
ovs-vsctl: Bridge does not contain a column whose name matches "protocols"
I assume without enabling OF1.3 for the switches, although I create mininet by giving OF1.3 as parameter, it won't work.
I am using Mininet 2.1 with ovs-vswitchd (Open vSwitch) 1.4.6 on Ubuntu 12.04.4.
Any help is appreciated.

Re: HP VAN SDN with mininet using OF 1.3
Did you initially try this URL: ?
https://<ip>:8443/sdn/ui/app/index
That will get you to login for the SDN Controller
Also:
https://<ip>:8443/api
Will get you to the RSDOC interface (no initial login required)

Re: HP VAN SDN with mininet using OF 1.3
Scott,
Thank you for pointers. Yes the API link was working but none other. I always was rendered with a blank page.. no error anywhere..
I got my 12.04 system working now. It is for now working as charm with mininet. Now trying to look at development.
Thanks again
Pradeep

Re: HP VAN SDN with mininet using OF 1.3
Hello,
Scott provided a nice write up on this topic that I posed to the Community Knowledge Base:
Supported versions of MiniNet for OpenFlow 1.0 and 1.3

HP SDN Team
