Hi Carlos,
I guess you also need to specify "maximum_unreplied_echo_requests" to enable
this feature.
I'm sorry I misunderstood. This feature seems to be disabled by the default.
On my environment, I could send Echo message periodically with;
$ cat etc/ryu/ryu.conf
# Sample configuration file
[DEFAULT]
#wsapi_host=<hostip>
#wsapi_port=<port:8080>
#ofp_listen_host=<hostip>
#ofp_tcp_listen_port=<port:6633>
echo_request_interval=1
maximum_unreplied_echo_requests=1
and run with;
$ ryu-manager --config-file etc/ryu/ryu.conf
I used the Python virtualenv and had no config file at the default location
(/usr/local/etc/ryu/ryu.conf), so I needed to specify "--config-file" option.
Thanks,
Iwase

Hello again Iwase,
Modifying the echo-request-interval and socket-timeout at the ryu.conf
file, doesn't seem to do anything.
Ryu still takes more than 2 minutes to detect a Switch Timeout.
This is what I have at ryu.conf
[DEFAULT]
echo_request_interval=1
socket_timeout=3

I also found those parameters in the code you just highlighted to me,
but as you said, they are not configurable via CLI options.
I will try to use ryu.cfg.

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,

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?
