No connections detected using OF1.3

I am building a SDN testlab with 4 HP 2920 connected with each other and hosts on every switch. I am trying both ODL 0.3.2 Lithium and 0.4.0 Snapshot 2565. As features I have installed odl-dlux-all and odl-l2switch-switch-all.

When using OpenFlow 1.0 on the switches everything works quite good (with high latencies).

But when I change the OpenFlow version to 1.3 on the switches, I do only see the 4 switches in the DLUX webinterface, no more connections beetween them and no hosts connected to them. Also ping between the hosts fails.

Thank you for your help in advance!

OF 1.3 will drop the LLDP flows by default. To solve that, you can install odl-l2switch-switch or add LLDP flows manually on your switches to forward LLDP packets to the ODL controller.

Installing odl-l2switsh-switch didn't help. What helped is that I changed the flow table from 0 to 100 in the files 52-loopremover.xml, 54-arphandler.xml and 58-l2switchmain. U can read the details at: https://lists.opendaylight.org/pipermail/l2switch-dev/2015-February/000525.html
