Hi Alioune and Cathy,
For devstack on ubuntu14.04, the default ovs version is 2.0.2, so there
was the error as Alioune said.
Do we need to install speical ovs version in networking-sfc devstack
plugin.sh?

Hi Alioune,
Which OVS version are you using?
Try openvswitch version 2.4.0 and restart the openvswitch-server before
installing the devstack.

Probleme with OpenStack SFC
Hi all,
I've installed Openstack SFC with devstack and all module are corretly running
except the neutron L2-agent
After a "screen -rd", it seems that there is a conflict between l2-agent and
SFC (see trace bellow).
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).
I would like to know:
- If someone knows why this error arrises ?
- is there another way to solve it ?
Regards,
