We do not have time to do this correctly.</p> <p>A workable solution is:</p> <p>1) On switch disconnect, in plugin, remove all of the flow, group, and meter for the node from the configuration tree.<br/> a) This can be done either by removing the FlowCabableNode Augmentation from the node or by removing all the Tables,Groups, and Meters. It should not be done by removing the Node.<br/> b) In the FlowTransaction, we will need to wrapper the call to the removeFlow RPC to catch the exception if the node is not services by a working switch.<br/> 2) On switch connect, in the plugin, send a message to the switch deleting all Flows, Groups, and Meters prior to the initial poll for stats (I'd recommend a barrier on this).</p> <p>Operating System: Mac OS<br/> Platform: PC</p> OPNFLWPLUG-57

Not handling switch reconnect and disconnect correctly

But at the end - tables are gone, node remains.</p> <p>Need to examine that closely.</p> <ul class="alternate" type="square"> <li>added meters ang groups</li> <li>tested on:</li> <li>cpqd (ok)</li> <li>and ovs (ovs OF-1.3 has currently issues regarding adding meter, but removing flows works, groups are not supported, OF-1.0 supports flows only and it works)</li> </ul> Development External issue ID 378 External issue URL Rank 0|i02ysv:
