Install
1.git clone bmv2、p4c-bm、p4ofagent、PTF and switch repositories.
bmv2:
> ./configure --with-pdfixed
> make
> make install
PTF:
> sudo python setup.py install
2.cd switch
> git submodule update --init --recursive
> ./autogen.sh
> ./configure --with-bmv2 --with-switchsai
> make
Run Tests
1.In terminal 1, start the software switch:
> sudo ./bmv2/run_bm.sh
2.In terminal 2, start the drivers:
> sudo ./bmv2/run_drivers.sh
3.In terminal 3, start tests.
> sudo ./bmv2/run_tests.sh
