Dears
Thanks Shinpei for your help.
I have fixed my issue but when I use this command 'ovs-ofctl dump-flows
mybridge' to get the flows deails it shows me this kind of error after
displaying few flows. Please note that when I disable writing metadata the
content is well displayed.
ovs-ofctl dump-flows mybridge

apply_actions must appear before write_metadata, for OpenFlow 1.1+
