The "ovs-ofctl dump-flows" command is going to dump out more data than "ovs-ofctl add-flows" needs. The error you're seeing is complaining about the first line of dump-flows output, which is "NXST_FLOW reply". Try removing that.
I just noticed that 1.6 and later releases don't properly read in regular flows either, since "ovs-ofctl add-flows" doesn't know to ignore the "idle_age" field. I just sent out a fix for review: http://openvswitch.org/pipermail/dev/2013-February/025036.html If you're using an affected release, until that gets checked in and a new release is out, you'll need to do some additional preprocessing on your flows. --Justin On Jan 31, 2013, at 11:56 PM, yue wang <heuye.w...@gmail.com> wrote: > Hi guys, > > I use the command: > ovs-ofctl dump-flows br0 > /root/flow_backup > > To save all flow entries into a file, but when i run: > ovs-ofctl add-flows br0 /root/flow_backup > > It says: ovs-ofctl: must specify an action. > I think the add flow syntax is not correct, so ho can i to dump flows to a > file, and restore them into ovs? > > > Thanks, > Heuye > > > _______________________________________________ > discuss mailing list > discuss@openvswitch.org > http://openvswitch.org/mailman/listinfo/discuss _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
