Re: [Ryu-devel] Question about getting msg with detail "ovs_bridge is not exists" (Chia Yen Yeh)

Hi, You must register the ovsdb_addr. Please start a rest_conf_switch and rest_qos as follows. # ryu-manager ryu.app.rest_qos And register the ovsdb_addr. Specify the value that you set in the set-manager command address and port number that you specify. curl -X PUT -d '"tcp:127.0.0.1:6632"'

Hi Satoshi, Thank you very much for replying back to me. I was out of town for a few days and got behind my emails. Ok I will try to setup openflow based on the switch config and try to go from there. I was trying to find examples somewhere online to see if someone did setup Ryu with an actual

Re: [Ryu-devel] Question about Ryu and Physical switch

Hi Ali, Ryu supports both switches physically and virtually. It is important that the switch is supporting OpenFlow protocol. You can find out the document of the switch for how to use. Thanks, Satoshi 2014-07-08 10:53 GMT+09:00 Ali Bagh : > Hi All, > > I want to connect Ryu to a physical switc

Hi All, I want to connect Ryu to a physical switch such as Quanta for example or Interface Masters or even Arista box. However, I can’t find any information how to do so. Could somebody please tell me how to do so? All the examples and talks are about virtual switches. I hope that does not mean

[Ryu-devel] Question about JSON for OF1.4 OFPMatch

Hi Fujita-san, I have a question about the desired JSON representation of OF1.4 OFPMatch. Currently the code serialises an OFPMatch as: "OFPMatch": { "oxm_fields": { "arp_op": 1, ... } } But the parser fails, complaining that "oxm_fields" is an unknown field
