[ovs-discuss] How to dump the flow from ovs and restore the flow to ovs?

[yue wang]

Hi Justin,

Thanks for your help, and i use ovs 1.7.1, after removing the first line,
and delete the idle_age column, i found the command "ovs-ofctl add-flows
br0 file1" works fine, so i will focus on this bug, and waiting for the new
release, thanks again.

Best regards,
Heuye
