Building p4runtime.proto
To include p4runtime.proto in the build, please run configure with
--with-proto.
PI CLI
For now the PI CLI supports an experimental version of table_add and
table_delete. Because these two functions have been implemented in the bmv2 PI
implementation, you can test the PI CLI with the bmv2 simple_switch. Assuming
bmv2 is installed on your system, build the PI and the CLI with ./configure --with-bmv2 && make. You can then experiment with the following commands:
simple_switch tests/testdata/simple_router.json // to start the switch
./CLI/pi_CLI_bmv2 tests/testdata/simple_router.json // to start the CLI
PI CLI> assign_device 0 0 -- port=9090 // 0 0 : device id + config id
PI CLI> table_add ipv4_lpm 10.0.0.1/24 => set_nhop 10.0.0.1 1
PI CLI> table_dump ipv4_lpm
PI CLI> table_delete ipv4_lpm <handle returned by table_add>
Contributing
All contributed code must pass the style checker, which can be run with
./tools/check_style.sh. If the style checker fails because of a C file, you
can format this C file with ./tools/clang_format_check.py -s Google -i <file>.
