I forced the opendaylight to use openflow 1.0.<br/> After the handshake, ODL is giving the following error and terminating the connection:</p> <p>Failed to prepare transaction member-1-datastore-operational-fe-0-chn-3-txn-0-0 on backend<br/> java.lang.IllegalArgumentException: Metadata not available for modification NodeModification</p> <p> </p> <p>I uploaded an example packet trace with two trials to <a href="https://www.cloudshark.org/captures/ce369e404d8d" class="external-link" target="_blank" rel="nofollow noopener">https://www.cloudshark.org/captures/ce369e404d8d</a></p> <p>The transaction in the karaf.log file is at <a href="https://pastebin.com/tC6CqE2x" class="external-link" target="_blank" rel="nofollow noopener">https://pastebin.com/tC6CqE2x</a></p> <p> </p> <p>Using kubuntu 18.04 and a Mikrotik router (model is hAP ac)</p> OPNFLWPLUG-1031

Bug High Resolved Cannot Reproduce Anil Vishnoi Onur Alp Thu, 23 Aug 2018 09:16:55 +0000 Mon, 18 Mar 2019 17:50:27 +0000 Mon, 18 Mar 2019 17:50:27 +0000 Fluorine-SR2 Neon 0 4 <p>It seems like the problem affects MikroTik brand routers causing them to be unmanageable by ODL.</p> <p>I tried ONOS controller with the same router and ONOS worked without problems.</p> <p>From the capture, it looks like the router does not respond to the port stats request message (packet 25) from controller.</p> <p>In that trial, there were no openflow ports assigned in the switch, so probably that was the reason for no reply. Also the error message is complaining about tables, not ports.  Now I assigned two ports to openflow and captured the traffic. It is available at <a href="https://www.cloudshark.org/captures/ce8f44e2de0d" class="external-link" target="_blank" rel="nofollow noopener">https://www.cloudshark.org/captures/ce8f44e2de0d</a> . You can see that the router is responding to the port stats message now. However opendaylight crashed again with the same error message.</p> <p>BTW, I saw that a similar error message was also reported last year but it was not solved.</p> <p><a href="https://ask.opendaylight.org/question/27367/openflow-plugin-error-failed-to-prepare-transaction-member-1-datastore-operational-fe-28-chn-29-txn-0-0-on-backend/" class="external-link" target="_blank" rel="nofollow noopener">https://ask.opendaylight.org/question/27367/openflow-plugin-error-failed-to-prepare-transaction-member-1-datastore-operational-fe-28-chn-29-txn-0-0-on-backend/</a></p> <p>can you grant permission to see the capture?</p> <p>Yes, it is open access now.</p> <p><a href="https://jira.opendaylight.org/secure/ViewProfile.jspa?name=ecelgp" class="user-hover" rel="ecelgp">ecelgp</a> Did you get the chance to look at the wireshark capture provided above?</p> <p>The trace is not fully dissected but it seems the switch reponds empty when asked for port stats. See packet 13 and 26.</p> <p>We have not heard from this, I think we can close it.</p> Development Rank 0|i03hzb:
