Problem with the “sudo p4run --config p4app.json” command regarding ping between hosts about p4-utils HOT 3 OPEN

Hi @Ga-Correia,

I am not sure if I understand your problem. But you should be able to ping between two hosts. For example by:

h1 ping h2

If the ping does not work, then the problem resides in the application you are running. You should debug the issue a bit more.

from p4-utils.

Yes, I did it as you showed, but between 2 hosts, ping only sent packets, but all were lost. Between 1 host and 1 switch, ping worked without problems. During the execution of the application, 5000 packets are being sent on the sender side, however on the receiving side there is a queue where the header decapsulation of these packets was supposed to be done, but it is always empty, indicating that nothing was received.

I don't know the details of that mininet-PINT project. But it looks like the problem is in the switch code. You should first debug why packets are dropped at the switch, otherwise, we have no idea if this is a logical issue in the p4 program or something external.
