No I did not run "controller ptcp:" but from the tutorial, it did not mention
to start "controller ptcp:". I thought we are going to run it as a hub.
When I run "controller ptcp:6653", there is no more 100%. When I run
"controller ptcp:", nothing happens. Is "controller ptcp:" supposed to work
without port number behind?

Did you run the command "controller ptcp:"? Delete the flow entry without
running this command and then try to ping. You should be unable to ping the
hosts in that case.

Hi,
But during the tutorial "Ping Test", before we add-flow to s1, the new flow was
not added to the flow table when I do "h1 ping -c3 h2". Are we able to delete
the flow table after it is added and make the switch work like the flow table
is empty from the beginning during the "Ping Test"?

Hi,
The flow table entry is deleted permanently, but when you do subsequent pings,
the controller that you are running adds the new flow table entries to the
switches. Try generating iperf traffic and you will see flow entries
corresponding to that traffic added as well.

Hi,
I'm following the tutorial on https://github.com/mininet/
openflow-tutorial/wiki/Learn- Development-Tools and while trying out the "View
OpenFlow Messages for Ping", I realized that "sudo ovs-ofctl del-flows s1" only
deletes the flow table temporarily? Subsequent ping from h1 to h2 will see the
flow table entry again when I execute "sudo ovs-ofctl dump- flows s1". How do I
actually permanently delete the flow entry which I added with add-flows command?
