It comes back if packets move through a node. This should not behave this way.</p> <p>The operational data should remain until the node goes away.</p> <p>See list conversation below for more details...</p> <p><a href="https://lists.opendaylight.org/pipermail/controller-dev/2014-August/006334.html" class="external-link" target="_blank" rel="nofollow noopener">https://lists.opendaylight.org/pipermail/controller-dev/2014-August/006334.html</a></p> <p>Operating System: Windows<br/> Platform: PC</p> CONTROLLER-735 operational data for OpenFlow disappears after a time delay if packets do not move through a switch Bug Resolved Cannot Reproduce Anil Vishnoi Coby B Soss Tue, 26 Aug 2014 22:16:18 +0000 Tue, 25 Jul 2023 08:24:07 +0000 Thu, 4 Sep 2014 13:54:02 +0000 restconf 0 3 <p>The switch is a virtual switch (OVS/QEMU)</p> <p>Hi Coby,</p> <p>I will try to recreate it locally, meanwhile can you please provide the steps you use to recreate it.</p> <p>Thanks<br/> Anil</p> <p>Hi Coby,</p> <p>I tested this with the latest code from controller and openflowpluging and things look fine to me. I did following tests</p> <p>I started controller from openflowplugin project, connected mininet and did pingall. It installs all the permanent flow to enable routing between hosts. I can see statistics of all flow in operational data store. I checked after 15 minutes and stats were still there. </p> <p>Then I installed one flow with idle_timeout== 60 seconds and after installation i can see statistics in operational data store. After 60 seconds flow gets expired and switch removes the flow. Once flow gets removed i can see that flow stats are also removed from operational data store and this is expected behavior.</p> <p>If you still see reported behavior please reopen the bug with instruction to recreate the bug.</p> <p>Thanks<br/> Anil</p> Development External issue ID 1625 External issue URL Rank 0|i02m8f:
