+**Warning**: Make sure that the configuration file you add after the `-O` option is adapted to your machine, especially to its isolated cores.

 **Note**: You may run OAI with O-RAN 7.2 Fronthaul without a RU attached (e.g. for benchmarking).
 In such case, you would generate artificial traffic by replacing the `--sa` option by the `--phy-test` option.
