The L2Switch project provides Layer2 switch functionality.

Running the L2Switch project Check out the project using git

git clone https://git.opendaylight.org/gerrit/p/l2switch.git

The above command creates a directory called "l2switch" with the project.

Run the distribution To run the karaf distribution, you can use the following command:

./distribution/karaf/target/assembly/bin/karaf

NOTE: if karaf doesn't boot up to console,It is suggested to clear the contents of distribution/target/assembly/data/cache

To run the base distribution, you can use the following command

./distribution/base/target/distributions-l2switch-base-0.1.0-SNAPSHOT-osgipackage/opendaylight/run.sh

If you need additional resources, you can use these command line arguments:

-Xms1024m -Xmx2048m -XX:PermSize=512m -XX:MaxPermSize=1024m'

Creating a network using Mininet

sudo mn --controller=remote,ip=<Controller IP> --topo=linear,3 --switch ovsk,protocols=OpenFlow13

sudo mn --controller=remote,ip=127.0.0.1 --topo=linear,3 --switch ovsk,protocols=OpenFlow13

The above command will create a virtual network consisting of 3 switches. Each switch will connect to the controller located at the specified IP, that is to say, 127.0.0.1.

sudo mn --controller=remote,ip=127.0.0.1 --mac --topo=linear,3 --switch ovsk,protocols=OpenFlow13

The above command has the "mac" option, which makes it easier to distinguish between Host MAC addresses and Switch MAC addresses.

Generating network traffic using Mininet

h1 ping h2

The above command will cause host1 (h1) to ping host2 (h2)

pingall

'pingall' will cause every host to ping all other hosts.
