Hi Carlos,
Ryu will detect the switch disconnection with sending OPFEchoRequest messages
periodically,
because eventlet's socket does not seem to raise the disconnection immediately
(due to the
non-blocking mode?).
If you need to detect switch disconnection more faster, please configure the
following options
in your "etc/ryu/ryu.conf".
These parameter does not seem to be configurable with the CLI options.

Thanks,
Iwase

Btw, when I ask for the Controller timout being configurable, I meant
for the socket timeout configuration.

Hello to all again.
I'm having an issue regarding the way ryu detects a switch disconnect.
When I remove the control ethernet cable, which my Zodiac FX switch
uses to connect to the Ryu controller, Ryu only generates the
disconnect event after some time (over a minute).
Shouldn't Ryu be generating the event right after a failure to receive
the periodic Hello Packets? Is the Controller timeout configurable?
