L2 MAC Learning Controller

This l2switch forwards ARP requests/replies to a controller that learns the MAC/port mappings and installs the appropriate table entries.

The class MacLearningSwitch in the python module maclearning.py can be used by mininet to create P4 runtime switches with initial table entries and controllers automatically.

Running

First, make sure you have p4app (which requires Docker):

cd ~/
git clone --branch rc-2.0.0 https://github.com/p4lang/p4app.git

Then run this p4app:

~/p4app/p4app run maclearning.p4app
