Simple_switch with physical interface

Getting Started with P4

Hi, I would like to ask about associating a physical interface to simple_switch. I am using the command sudo simple_switch -i 0@ens3 -i 1@ens4 basic.json. and have added a table via simple_switch_CLI.

When I ping the server, it doesn’t work and when I tcpdump the server, it shows ICMP request but the client doesn’t show ICMP reply. is there a problem with simple_switch or it only supports virtual ethernet?
Thank you.

*btw, I am using pnetlab.

This Github issue, and in particular the comment by Antonin Bas that I am linking directly to, may have useful tips: Performance issue of simple_switch_grpc · Issue #1172 · p4lang/behavioral-model · GitHub
