OVSDB:dlux mininet

This was last updated for the Helium release and needs to be updated. Please bear that in mind when reading the content and feel free to help update it.

This page is a place to capture notes on running the Helium release with mininet.

1. Download and unzip the latest [Helium] release:

http://www.opendaylight.org/software/downloads

2. Start karaf:

cd into unzip dir
bin/karaf

3. Install the required features:

feature:install odl-base-all odl-aaa-authn odl-restconf odl-nsf-all odl-adsal-northbound odl-mdsal-apidocs odl-l2switch-switch odl-dlux-core

4. Build mininet to ensure we have OpenFlow13 support:

- To use the OpenFlow13 version I downloaded the latest code for mininet from 08/21/14. Anything later should be fine.
- There were previous comments that required patching mininet to gain OpenFlow13 but that was not necessary with the latest code.

git clone git://github.com/mininet/mininet
git checkout -b 2.1.0p1 2.1.0p1
sudo ./mininet/util/install.sh -n

These were the previous instructions for modifying mininet to support OpenFlow13:

Look in '/opt/mininet/mininet/node.py' for something like "set bridge %s protocols=%s' % ( self, self.protocols )"

After I edit that file I copy it: sudo cp /opt/mininet/mininet/node.py /opt/mininet/build/lib/mininet/node.py

Then build via ./install.sh -n.

Probably don't need the cp to the build lib since I think the install does that but it doesn't hurt.

More details on this step can be obtained here: https://lists.opendaylight.org/pipermail/ovsdb-dev/2014-June/000490.html and here https://github.com/dave-tucker/mininet/commit/21323c27347f98fbb416e6310296cea9339fc945

5. Start mininet: sudo mn --mac --switch=ovsk,protocols=OpenFlow13 --controller=remote,ip=${ODL_IP},port=6653 --test pingall - runs a ping sanity

sudo mn --mac --switch=ovsk,protocols=OpenFlow13 --controller=remote,ip=${ODL_IP},port=6653 --topo=tree,3

- creates a three layered topology of 7 switches and two attached hosts.

Note 1: Substitute ${ODL_IP} with the IP address or where ODL (from Karaf) is running.

Note 2: To in order for the above commands to work under Fedora 20, I had to first install and start openvswitch with the commands:

sudo yum install openvswitch

sudo systemctl start openvswtich.service

6. Verify topology in DLUX:

http://${ODL_IP}:8181/dlux/index.html

For Lithium use:

http://<controller-ip>:8181/index.html


If ODL is running on localhost, you can use this: http://localhost:8181/dlux/index.html

The default user/pass is admin/admin.

At this point you should see the topology in the gui.
