<p class="MsoNormal">Hi all, <u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">I've installed Openstack SFC with devstack and all module are corretly running except the neutron L2-agent<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"><u></u> <u></u></p>
</div>
<div>
<p class="MsoNormal">After a "screen -rd", it seems that there is a conflict between l2-agent and SFC (see trace bellow).<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">I solved the issue with "sudo ovs-vsctl set bridge br protocols=OpenFlow10,OpenFlow11,OpenFlow12,OpenFlow13" on all openvswitch bridge (br-int, br-ex, br-tun and br-mgmt0).<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">I would like to know:<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"> - If someone knows why this error arrises ?<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal"> - is there another way to solve it ?<u></u><u></u></p>
