Start ODL, enable l2switch, openflow, restconf, dlux. Stop ODL <br/> 2. Start mininet using command: sudo mn --controller=remote,ip=127.0.0.1 --topo linear,2 --switch ovsk,protocols=OpenFlow13<br/> 3. Start ODL<br/> 4.

Go to mininet and run: sh ovs-ofctl dump-flows s1</p> <p>There will not be any flows installed. If you start ODL before mininet then the default flows are installed.</p> <p>Not sure if this is a L2switch bug or if L2switch is trying to install default flow and failing. There are no error messages in the log.</p> <p>Operating System: All<br/> Platform: All</p> L2SWITCH-28 If mininet is started before the OpenDaylight instance, default flows are not installed Bug Resolved Cannot Reproduce Unassigned Ramkumar Gowrishankar Wed, 10 Dec 2014 19:11:04 +0000 Thu, 19 Oct 2017 21:28:25 +0000 Wed, 27 Apr 2016 17:26:31 +0000 unspecified General 0 2 <p>For some weird reason, it only happens if the following features are part of the org.apache.karaf.features.cfg file: odl-adsal-northbound,odl-restconf,odl-openflowplugin-all,odl-mdsal-apidocs,odl-dlux-core<br/> And then the odl-l2switch-all is installed. </p> <p>If I try to install the features manually, then I cannot reproduce it consistently.</p> <p>Please let us know if it still doesn't work you.</p> <p>I could see default flows installed using out of box of l2switch module.</p> Development External issue ID 2502 External issue URL Rank 0|i01z3j:
