Thank you, I have tested again, and found the ryu controller reply an packet like openflow 1.5, but my wireshark tool can not analyses because My wireshark version is 1.12.6, only support openflow 1.0, 1.1, 1.2, 1.3, 1.4. The problem is now: 1. openflow switch send an OFPT_HELLO with version 1.3, openflow packet content is 04 00 00 08 9d 69 b9 e2 ----- > 04 tells this is a openflow version is (0x04) 1.3, and 00 means this is a ofpt_hello 2. ryu controller received the hello packet, and send a reply, but the content is 06 00 00 08 2f 9d 48 7a -----> 06 means this is a openflow version is (0x04) 1.5?
My ryu version is 3.19 and I start my ryu just using the default setting [root@localhost bin]# ./ryu-manager loading app ryu.controller.ofp_handler instantiating app ryu.controller.ofp_handler of OFPHandler does ryu-3.19 need some special setting to reply OFPT_HELLO with version 1.3? Anybody knows please help, thank you very much~~ -----邮件原件----- 发件人: Yusuke Iwase [mailto:[email protected]] 发送时间: 2015年7月29日 8:30 收件人: shenwei (G) 抄送: [email protected]; [email protected]; yuanfeng (A) 主题: Re: [Ryu-devel] A question about OFP Hello process of RYU 3.19 ofp_handler.py，anyone knows please help， thank you Hi, Because Ryu supports OpenFlow1.4 and OpenFlow1.5, Ryu sends a Hello message with version 0x06. So you can not filter it by "openflow_v4". Wireshark shows a Hello message with "Unsuported version not dissected". Please use "openflow" as the filter keyword instead.
