(1) Connect Tofino & Clone P4 Code

  ssh [username]@[IP]    # Replace your username & Tofino IP
  pass: xxxx             # Tofino password

  # Clone the Repository on your Tofino
  git clone https://github.com/dcomp-leris/ARCG-DP-Deployment.git
  cd ARCG-DP-Deployment/Tofino/V2

Output:

(2) Compile the P4 Code in Tofino

  # Check to be in the froject folder
  ~/../p4_build.sh -p RF.p4

Output:

(3) Run the P4 code

  # Run compiled P4 code (RF) on Tofino2
  ~/../run_switchd.sh  -p RF --arch tf2

Output:

(4) Run the Controllr code
