Hi Dave,
Thanks for your reply.
I have attached the configuration detail in the email, Please let me know
if you need more information on the same.
Joe, I just want to check sctp traffic communication between two ovs
bridge, i was expecting that i should see sctp traffic, able to see tcp and
udp traffic between two bridge but sctp traffic is not seen.
Please check the attached configuration detail .
Regard,
Soumya
