Hi Bertrand, Thanks for the info - we will give it a try & update on results.
Thanks!

This has been merged in the master branch and for Boron SR3. >From the logs it looks like you are using Boron SR2, so perhaps give the >most-recent 0.5.3 SNAPSHOT a look.

He did so while capturing the openflow port, and also openflowplugin in TRACE. Both the log & the wireshark trace are attached to the ticket.

Anyway maybe some dev can figure out something but just looking at the karaf log you posted.

Unfortunately I’ve restarted the environment already, so I can’t get a wireshark capture (I believe it shouldn’t be too hard to reproduce if it’s really needed) Thanks Koby From: Luis Gomez [mailto:[email protected]] Sent: Thursday, February 23, 2017 8:14 PM To: Aizer, Koby <[email protected]<mailto:[email protected]>> Cc: openflowplugin-dev <[email protected]<mailto:[email protected]>> Subject: Re: [openflowplugin-dev] OVS connection fails to restore after ODL restart Hi Koby, I think this is not enough information to understand your issue, can you please open a bug and attach a karaf log and a wireshark trace of the controller restart + switch fail to connect?

I searched openflowplugin’s Bugzilla, and I saw there is already a similar bug on this issue [1]– though the described scenario is a bit different (OVS restart instead of ODL restart). I couldn’t find a way to recover from this situation (I tried restarting OVS several times and I even tried an ODL restart) – it seems that ODL got to a state where it can’t reconnect to that switch. Is there some known workaround for this? Any plans to fix this issue?
