OpenFlow 1.1 and later support is experimental. Thanks for trying it out and reporting a problem. > Have a look at two wireshark sessions at: > > http://picpaste.com/pics/of-1.2-CqqrPKPw.1378906446.png That picture is almost unreadably fuzzy because it is an 1852 x 1113 image scaled down to 640 x 384. If you post screenshots, please make sure them readable. > The left window is me talking 1.2 and the right window is the result > of this command: > > ovs-ofctl --protocol=OpenFlow12 add-flow 'tcp:192.168.1.120:6633 > lsw' 'in_port=1,dl_src=86:d7:3c:a1:bb:d5,dl_type=0x8000 > actions=mod_nw_src:192.168.111.111' "lsw"? > Look at the Action Type! I'm looking at it. It looks like a bunch of fuzz. It *might* say 00 10 on the left and 00 05 on the right. Oh, I guess that "set-field" is 25 so that must be 00 19 on the left. > Is it a bug? Is it intentional? or what? OpenFlow 1.1 uses action 5 to mean OFPAT_SET_NW_SRC. OpenFlow 1.2 action numbering is backward-compatible with OpenFlow 1.1, so presumably it means that same thing in OpenFlow 1.2. I guess the point you're trying to make is that OVS should translate mod_nw_src into set_field for OF1.2? That's reasonable; I'll make a note. > Btw: when I send the proper 1.2 message, I get the following in the > daemon.log: > > ovs-vswitchd: ovs|11535|meta_flow|WARN|destination field ip_src > lacks correct prerequisites Based on the command you provided above, this is probably because you think that 0x8000 is the ethernet type for IPv4.
