Hi venkatamahesh,

I am not able to reproduce this locally. Can you please provide the following information:
1. local.conf for the devstack that is throwing the above error.
2. Version of neutron that you are using.
3. Full log of the error.

Hi Anindita,

I am installing networking-sfc to existing devstack setup. According to networking-sfc documentation I have done steps and after that while restarting the services I got this error.

And Did you install networking-sfc ?

Thanks
mahesh
