Hi,
while Ryu supports OpenFlow 1.0, 1.2 and 1.3, the simple_switch.py example
works with OpenFlow 1.0 only (search for v1_0 in the source code for
details).
As LINC switch uses OpenFlow 1.3 by default, and does not support OpenFlow
1.0, you get that "closed because of bad_initial_message" output.
A patch for OF 1.2 compatibility for simple_switch.py was posted on this
list
some time ago. Using that and setting the backend to linc_us3 in the
LINC switches sys.config should make it work.
Cheers
Jeremias
