Which mininet/OVS version are you using for this test? I will try this later today. Also cc-ing l2switch people.

Hello Daniel Farrell, Good day to you. I am using mininet(version 2.2.0b1) and ODL beryllium controller(distribution-karaf-0.4.0-Beryllium.tar.gz) Currently I am doing benchmarking draft test for "Reactive path provisioning time & rate" of ODL beryllium controller using mininet. I executed the following commands in controller PC, export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64 export JAVA_MAX_MEM=2072M tar -xvzf distribution-karaf-0.4.0-Beryllium.tar.gz ./distribution-karaf-0.4.0-Beryllium/bin/karaf feature:install odl-restconf-all odl-l2switch-switch odl-openflowplugin-all odl-dlux-all odl-openflowplugin-flow-services-ui odl-l2switch-hosttracker Then I did the following changes to make the ODL controller in reactive mode, Location: [ODL-folder]/etc/opendaylight/karaf I changed <is-proactive-flood-mode> to false from true in file 54-arphandler.xml. Also changed <is-install-dropall-flow> to false from true in file 58-l2switchmain.xml. After that I did ./karaf clean following by installed the following feature's, "feature:install odl-restconf-all odl-l2switch-switch odl-openflowplugin-all odl-dlux-all odl-openflowplugin-flow-services-ui odl-l2switch-hosttracker" Then I executed the following commands in mininet PC, mn --controller=remote,ip=33.33.33.1 --topo=linear,16 --switch=ovsk,protocols=OpenFlow13 --mac pingall h1 ping h10 h1 ping h2 h1 ping 11 h1 ping h16 exit The h1 ping upto h8 is working fine. The pingall, h1 ping h10 & h1 ping h16 is not working in above commands. Could you please help me to rectify this problem? Could you please clarify whether any other controller configuration need for reactive mode? Note: Sporadically sometime h1 ping h2 also not working.
