This is a very potential scale issue, as there will be a lot of applications listening on port delete and add events to handle their flow programming logic.</p> <p>The fix in openflowplugin makes sure that a PortReason flag comes along with port removal event, which helps in distinguishing between a port removal and a node removal. The corresponding fix in genius makes use of this flag to handle genuine port deletes</p> <p>Please merge the patch to master and cherry pick to the oxygen branch.</p> <p><a href="https://jira.opendaylight.org/secure/ViewProfile.jspa?name=klou" class="user-hover" rel="klou">klou</a> <a href="https://git.opendaylight.org/gerrit/#/c/68794/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/68794/</a> is cherry-picked and +2 ready for merge to Oxygen...</p> Blocks OPNFLWPLUG-963 Development Rank 0|i03atz:
