Hello,
I'm using OpenFlow reference implementation v1.3 switch (CPqD/Ericsson) and
Ryu controller.
My Ryu controller app is based on the L2 forwarding switch example.
Whenever I start my controller, it receives the 'hello' message from the
switch and goes to config mode. It just freezes in the config mode; it's
not sending the switch features request message.
But, it works perfectly when used in Mininet environment. I'm seeing this
issue in a physical setup.
See below for Ryu logs (physical/mininet environment) and commands used to
execute the switch and controller.
Any help would be appreciated.
Thanks,
/Aravind
