Hi, Excuse me for jumping in.
As knet solutions said, the OpenFlow Spec 1.3 does not provide "tcp_flags" match field, so ofctl_rest does not support it. https://github.com/osrg/ryu/blob/6456711a343bd9999491bee2eb059c218170cc50/ryu/lib/ofctl_v1_3.py#L194 On the other hand, ovs-ofctl implements "tcp_flags" match field by using OVS's own extension match field(Nicira Extended Match), so you can install "tcp_flaga" via ovs-ofctl. In Ryu, you can refer the OVS version "tcp_flags" math as "tcp_flags_nxm". https://ryu.readthedocs.io/en/latest/nicira_ext_ref.html#module-ryu.ofproto.nicira_ext But written in the above, ofctl_rest does not support the Nicira Extended Match yet. 2019年6月23日(日) 20:50 Alon Dotan <alon.do...@bullguard.com>: > ovs-ofctl add-flow br-dp0 > priority=20478,tcp,in_port=1,tcp_flags=2,table=0,actions=mod_dl_dst:00:00:00:00:00:01,output:3 > Im using ubuntu ovs 2.9.2 and didnt set manually the openflow version so I > guess the default is 1.3 > > this is the table0 dump: > cookie=0x5adc15c0, duration=3874.646s, table=0, n_packets=279, > n_bytes=22481, priority=20480,udp,in_port=ens4,tp_dst=53 > actions=mod_dl_dst:00:00:00:00:00:01,output:vethb73cf48a > cookie=0x5adc15c0, duration=3874.645s, table=0, n_packets=0, n_bytes=0, > priority=20479,udp6,in_port=ens4,tp_dst=53 > actions=mod_dl_dst:00:00:00:00:00:01,output:vethb73cf48a > cookie=0x5adc15c0, duration=3874.644s, table=0, n_packets=530, > n_bytes=43639, priority=20478,tcp,in_port=ens4,tp_dst=80 > actions=mod_dl_dst:00:00:00:00:00:01,output:vethb73cf48a > cookie=0x5adc15c0, duration=3874.644s, table=0, n_packets=0, n_bytes=0, > priority=20477,tcp6,in_port=ens4,tp_dst=80 > actions=mod_dl_dst:00:00:00:00:00:01,output:vethb73cf48a > cookie=0x5adc15c0, duration=3874.646s, table=0, n_packets=277, > n_bytes=43823, priority=20480,udp,in_port=ens5,tp_src=53 > actions=mod_dl_dst:00:00:00:00:00:02,output:veth91fe926b > cookie=0x5adc15c0, duration=3874.645s, table=0, n_packets=0, n_bytes=0, > priority=20479,udp6,in_port=ens5,tp_src=53 > actions=mod_dl_dst:00:00:00:00:00:02,output:veth91fe926b > cookie=0x5adc15c0, duration=3874.644s, table=0, n_packets=507, > n_bytes=747670, priority=20478,tcp,in_port=ens5,tp_src=80 > actions=mod_dl_dst:00:00:00:00:00:02,output:veth91fe926b > cookie=0x5adc15c0, duration=3874.644s, table=0, n_packets=0, n_bytes=0, > priority=20477,tcp6,in_port=ens5,tp_src=80 > actions=mod_dl_dst:00:00:00:00:00:02,output:veth91fe926b > cookie=0x5adc15c0, duration=3874.640s, table=0, n_packets=0, n_bytes=0, > priority=20474,icmp6,in_port=ens4,icmp_type=134 actions=drop > cookie=0x5adc15c0, duration=3874.645s, table=0, n_packets=891, > n_bytes=798051, priority=20480,in_port=vethb73cf48a actions=resubmit(,1) > cookie=0x5adc15c0, duration=3874.645s, table=0, n_packets=1009, > n_bytes=80696, priority=20480,in_port=veth91fe926b actions=resubmit(,1) > cookie=0x5adc15c0, duration=3874.640s, table=0, n_packets=6438, > n_bytes=7853031, priority=20476,in_port=ens5 actions=resubmit(,1) > cookie=0x5adc15c0, duration=3874.640s, table=0, n_packets=6215, > n_bytes=855625, priority=20473,in_port=ens4 actions=resubmit(,1) > cookie=0x0, duration=3864.277s, table=0, n_packets=410, n_bytes=31472, > priority=20478,tcp,in_port=ens4,tcp_flags=syn > actions=mod_dl_dst:00:00:00:00:00:01,output:vethb73cf48a > cookie=0x0, duration=3864.271s, table=0, n_packets=0, n_bytes=0, > priority=20478,tcp,in_port=ens5,tcp_flags=syn > actions=mod_dl_dst:00:00:00:00:00:02,output:veth91fe926b > cookie=0x5adc15c0, duration=3874.641s, table=0, n_packets=0, n_bytes=0, > priority=20476,udp,in_port=ens4,tp_src=67,tp_dst=68 actions=drop > cookie=0x5adc15c0, duration=3874.640s, table=0, n_packets=0, n_bytes=0, > priority=20475,udp6,in_port=ens4,tp_src=547,tp_dst=546 actions=drop > cookie=0x5adc15c0, duration=3874.622s, table=0, n_packets=0, n_bytes=0, > priority=0 actions=drop > > Thanks, > ------------------------------ > *From:* knet solutions <knetsolutio...@gmail.com> > *Sent:* Sunday, June 23, 2019 2:28 PM > *To:* Alon Dotan > *Cc:* Ryu-devel > *Subject:* Re: [Ryu-devel] ofctl_rest app tcp flags > > 1. could you share the ovs-ofct command which you use? > 2.
