Tests in this folder use UP4 ONOS APIs (P4Runtime) to simulate the attachment and detachment of UEs. Tests also verify upstream and downstream traffic by checking that GTP encapsulation and decapsulation is correctly performed by the UPF (implemented by the leaves switches). The testing topology a paired-leaves topology.
The UP4 test uses the P4RuntimeCliDriver. This driver requires the p4runtime-shell to be installed on the ONOS Bench machine To install it run python3 -m pip install p4runtime-sh==0.0.2 (requires Python>3.7).
The driver also requires an ipython config file. The file should contain the following lines:
c.InteractiveShell.color_info = False c.InteractiveShell.colors = 'NoColor' c.TerminalInteractiveShell.color_info = False c.TerminalInteractiveShell.colors = 'NoColor'
and can be placed in <IPYTHONDIR>/profile_default/ipython_config.py. A different location for the ipython config folder can be set via the IPYTHONDIR , in that case the ipython_config.py file can be placed in <IPYTHONDIR>/profile_default (more info at https://ipython.readthedocs.io/en/stable/development/config.html).
