HP VAN SDN with mininet using OF 1.3

Dave-B — Thu, 17 Apr 2014 10:49:32 GMT

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.

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.

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.

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.

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)

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

Hello,

Scott provided a nice write up on this topic that I posed to the Community Knowledge Base:

ovs 1.4.6 does not support Of1.3.
