Running the exercises can race:
$ make run
mkdir -p build pcaps logs
p4c-bm2-ss --p4v 16 --p4runtime-file build/basic.p4info --p4runtime-format text -o build/basic.json basic.p4
sudo python ../../utils/run_exercise.py -t topology.json -b simple_switch_grpc
Reading topology file.
Building mininet topology.
Switch port mapping:
s1: 1:h1 2:s2 3:s3
s2: 1:h2 2:s1 3:s3
s3: 1:h3 2:s1 3:s2
Configuring switch s3 using P4Runtime with file s3-runtime.json
- Using P4Info file build/basic.p4info...
- Connecting to P4Runtime server on 127.0.0.1:50053 (bmv2)...
- Setting pipeline config (build/basic.json)...
