Sometimes the controller does not discover all nodes (I saw 2 nodes out of 15 reported), sometimes (almost always) the right number of flows is not programmed into the network (i.e. flows are missing).</p> <p>To reproduce:</p> <ul class="alternate" type="square"> <li>Start the controller</li> <li>Program 5k flows into the config data store</li> <li>Start mininet which will connect to the controller</li> <li>Lookup the number of flows in programmed mininet,</li> <li>Check the number of flows reported in the controller</li> <li>Check inventory and topology</li> </ul> <p>Operating System: All<br/> Platform: All</p> OPNFLWPLUG-417

Starting mininet with flows programmed into the config data store

Bug Resolved Done Jozef Gloncak Jan Medved Sat, 25 Apr 2015 05:51:48 +0000 Mon, 27 Sep 2021 09:01:29 +0000 Wed, 3 Jun 2015 09:13:47 +0000 General 0 1 <p>Regarding problem with right number of flows. This problem is when deleting.</p> <p>I tested on mininet, ovsk with 3000 flows. For deletion and also for addition it sometimes (unpredictably) happen that 3000 OFPT_FLOM_MOD (OFPFC_ADD or OFPFC_DELETE_STRICT) is generated but not everything is successful sent to device (switch)</p> <p>There is also other problem when controller is running and mininet is connecting to it. Sometimes it happen that not all flows are sent to device and consquentely saved to operation datatore. Problem is somewhere between FlowForwarder - method add() from forwardingrules-manager and SalFlowServiceImpl - method addFlow() from openflowplugin-impl</p> <p>I've done 10 attempts.</p> <ul class="alternate" type="square"> <li>I've started karaf.</li> <li>I've started mininet with 15 switches.<br/> Result:</li> <li>After few moments 15 nodes has appeared in operational datastore.</li> </ul> <p>So I haven't been able to replicate your problem with only 2 discovered switches.</p> <p>This problem is no more observed</p> Development External issue ID 3061 External issue URL Rank 0|i0310v:
