[sfc-dev] Not getting dumps on OVS bridge(SFF)

Thanks for your reply.
Are you using specific openflow switch for testing sfcofl2 feature (if not to use mininet.)

Is there any approach to configure SF with SFF once SFF (ovs bridge) is configured using SFC-OVS feature.
Which SFC feature I should follow?

I need to check dumps on ovs bridge and packet to be forwarded to a SF interface.

Thanks & Regards
Rajani Srivastava

 =======================
   Currently the SFCOFL2 only supports OFS and does not support OVS.

These traces are for OpenFlow Switches. Seems like there is an error in 
the SFCOFL2 code, as it should not try to write flows to a 
"non-openFlow" switch.

Could you write a Bug report please: https://bugs.opendaylight.org/

Regards,

Brady
