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
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

Thank you Iwase
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

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 generatin
Hi,
Someone else on this list can probably give you a more complete answer. It
should be possible by using ryu to write to ovsdb to change the switches

Is it possible to dump information to find out which of the ports of the

Thanks Fujita,
I solved the switch feature problem but!!!
As I explained before in my project I should add some extra functionality
to the ryu controller in order to handle this feature in my openflow
switch.
So in this direction in ofproto_v1_3.py and ofproto_v1_3_parser.py I added
2 extra struct

Hi all,
I am a newbie in developing an application using Ryu.
Since I have added extra functionality to my openflow 1.3, I need the
controller app send the feature request to the switch to inquiry about the
new added feature.
But by running

Hi Fujita,
Thank you so much for the response. That helped alot. One other small issue
is that Im trying to match on TCP source port for IPv6. The match
parameters I give is TCP source port = 2000+protocol=6(for

Hi Fujita,
Thank you so much for the response.
What I am trying to achieve is incrementally pass flow with the combination
of matches. For Example, I first pass a flow with match on ethertype, next
with match on ethertype and source MAC, then with match on ethertype,
source MAC and destination MA

You can specify table number as table_id argument here like.

Hi Fujita,
Few more details are: The flow programs fine in L2 mode of the switch
because there is only 1 table. However we are suspecting that always table
0 goes out because of which the L3 mode of the switch is rejecting the flow.

Hi Fujita,
Thanks for the response.
I wanted to know if we can specify the table number on the switch side when
we are trying to install the flow? The switch architecture is different
compared to traditional Openflow switches. We have a L2 mode where we can
install only L2 flows and L3 mode where

Hi Fujita,
Thank you so much for your response! It worked perfectly with that change!
I have another small query. When I pass the flow onto my switch I see the

Hi Satoshi,
Thank you so much for the response.
My end goal is to pass a flow to the switch as soon as its up using OFv1.3.
I have written the following snippet of code but Im not sure where I am
going wrong. I would be obliged if you could help me out in this regard.

Hi Vinay,
You can use EventSwitchEnter and EventSwitchLeave.
(Note that this API is supported only by OpenFlow 1.0 and 1.3)
