Developers Environment

To have a working simulator to use with the p4Runtime integration in ONOS you have two options:

• download a prebuilt image of the machine
• build your own machine

Download Pre-Built VM

Build Your own VM

The following steps will help you set up a development environment with Mininet, ONOS and BMv2 with P4Runtime support.

...

1. Clone ONOS repository. On your Mininet VM shell, type:

   Code Block
   language bash
   cd ~ git clone https://github.com/opennetworkinglab/onos.git

2. Source ONOS's bash_profile. On your Mininet VM shell, type:

   Code Block
   language bash
   echo "source ~/onos/tools/dev/bash_profile" > ~/.bashrc source ~/.bashrc

   Important: replace .bashrc with your shell configuration profile (.bash_aliases, .profile, etc.)

3. Build and install P4 tools. We have prepared a special command to install everything in one shot! On your Mininet VM shell, simply type:

   Code Block
   language bash
   onos-setup-p4-dev

   This command will download, build and install BMv2 (with the simple_switch_grpc target), P4Runtime libraries, the P4 compiler p4c, the old BMv2 compiler p4c-bmv2, and all required dependencies (including protobuf and gRPC). This command takes approx. 20 minutes to complete with the minimum system configuration described before.
   if you run out of space on you mininet machine you can go inside the p4tools folder in the home directory:

   Code Block
   language bash
   cd ~/p4tools

   then go in one of the local directories, e.g. p4rutnime

   Code Block
   language bash
   cd p4runtime

   and clean the make artifacts with

   Code Block
   language bash
   make clean

4. Build the example P4 programs. On your Mininet VM shell, type:

   Code Block
   language bash
   cd ~/onos/tools/test/p4src/p4-16/ make all

5. TBC

Run the Simulator 

Start Mininet, using BMv2 simple_switch_grpc target. 

Go in the home directory:

cd ~

On your Mininet VM shell, type:

sudo -E mn --custom $BMV2_MN_PY --switch onosbmv2 --controller remote,ip=192.168.56.1

Be sure to use the correct IP address of your ONOS instance.
