Hello,
I hope this list is still the proper avenue for submitting a patch. I
believe I've fixed a bug in the ovsdb api
(ryu/services/protocols/ovsdb/api.py) in which a lambda function had an
extra parameter causing an error when using the del_port_by_name function.
I've attached the patch.
Thank
OFPFlowMod is used to create and modify OpenFlow rules on the switch.
PacketOut is used to send a packet that has reached the openflow controller
(ryu) back to the switch.
You can find them both documented here
http://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html.
There is also an example of
Hi,
By default when a Ryu application is started, it is listening for a
connection request that comes from the switch. (For instance, using ovs,
you would run ovs-vsctl set-controller to tell it where to talk to the Ryu
application). However, OpenvSwitch can also behave like a server and wait
for
not the other way around?

Hello,
I found a misleading error message in a try except block. This message
should only be printed in the case of a poorly formed openflow message,
however it was being printed for almost every exception. Patch is attached.
Thanks,
Matt

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
controller (probably by using the set_controller method in
ryu/services/protocols/ovsdb/api.py). There is also some code being worked
on that will

Fortunately I have an update on the issue from above. The class
OFPFeaturesRequest(MsgBase): appears to be missing the @_register_parser
decorator. I can push a patch for this but I will continue testing the code
today.

What version of OpenFlow are you using? Some appear not to support
table_id. For instance:

Hi Jose,
Can you be more specific about what kind of information you are looking
for? There are a lot of utilities for viewing stats about existing openflow
rules/ groups, etc.

Sami,
I think you are asking 'How can I interact with Ryu from another
application?' I'd recommend using ofctl_rest api (1st link) or adding your
own (2nd link).
