Dear Iwase,
could you please me help me out, how to "set-field action" to set vlan_vid
for OpenFlow 1.3 version (HP openFlow Switch). It throws an error when
I followed the example "http://ryu.readthedocs.io/en/
latest/app/ofctl_rest.html?highlight=ofctl#example-of-vlan-id-match-field".
I am trying to install through ofctl_rest.py
for example, I would like to set vlan_vid:2? how can I set it please let
me know.
