I run the mininet with:

sudo mn --topo single,3 --controller remote,ip=... port=6653 --switch ovsk, protocols=OpenFlow13 Then I run the controller OpenDaylight(Helium,Karaf). I installed features: odl-openflowplugin-all , odl-dlux-core, odl-restconf, odl-mdsal-apidocs, odl-openflowplugin-flow-services-ui, odl-openflowplugin-flow-services-rest

Then I add the flow from the computer which mininet runs, manually by 

sudo ovs-ofctl -O OpenFlow13 add-flow "s1" in_port=1,actions=output:2
sudo ovs-ofctl -O OpenFlow13 add-flow "s1" in_port=2, actions=output:1

Then I use "pingall" command at mininet promt. As it is expected h1 and h2 can ping each other while they couldn't ping h3.

Finally, I tried to check the flow from Dlux GUI, however what I saw was the only switch. Then I tried to look at flows, and again couldn't see anything.

What is the problem? If anyone can helps I would be gratefull

Thanks in advance

run the ping-all command in mininet. It shows whether pings are successful or not. If pings are successful then you will be able to see hosts also.

Stop the running controller and check for the port 6633 by running the command,

ps -eaf | grep ":6633"

If any of the service is running on this port, kill them by the command

sudo kill -9 pid #pid: Process ID of the running service

then, try to install these features:

opendaylight-user@root>feature:install odl-l2switch-switch odl-restconf odl-mdsal-apidocs

Now, start the mininet and check for connectivity between controller and mininet.
