 Description   

I am using Openflowplugin alternate design (openflowplugin*-li features) with ovsdb and when ovsdb tries to install flows to the switch, it sees following exception. I think this will happen irrespective to whatever openflowplugin design you use. Because of this flow installation is failing.

This can be related to https://bugs.opendaylight.org/show_bug.cgi?id=4473, right?

Comment by Anil Vishnoi [ 04/Jan/16 ]

yes luis, it looks like we need this patch.

Comment by Robert Varga [ 27/Jan/16 ]

TunIpv4SrcCodec needs to implement HeaderDeserializer interface. Unfortunately the registry implementation is not really helpful with diagnosing this mismatch.

https://git.opendaylight.org/gerrit/33633 adds the appropriate catch, with a warning and recovery code.

The real fix must be delivered to openflowplugin, though.

Comment by Shuva Jyoti Kar [ 19/May/16 ]

cherry picked Robert's changes to master to catch the ClassCastException

Hello Shuva,

What is the status here? Are there still some issues or it can be closed?

Thanks,
Miro

Comment by Shuva Jyoti Kar [ 27/Aug/16 ]

we don't see the ClassCast exception but as mentioned by Robert, the correct fix is to implement HeaderDeserializer interface and that should be done in the ofplugin

Created patch that implements HeaderSerializer and HeaderDeserializer for match nicira extensions here: https://git.opendaylight.org/gerrit/#/c/58117/

Comment by Tomas Slusny [ 22/Jun/17 ]

Fix for this bug was merged, so I am closing this one for now. Please reopen if you are still facing this issue.
