Hi Marko,
How about the following?
http://ryu.readthedocs.io/en/latest/ofproto_v1_3_ref.html#port-status-message
You can use;
@set_ev_cls(ofp_event.EventOFPPortStatus, MAIN_DISPATCHER)
to detect link state changes.
Thanks,
Iwase

Hello,
I am trying to write a Ryu app that will be able to get link status. I would
like to find a way to notify the controller about the reason why link is down
(e.g. by using OFPPS_LINK_DOWN message), and trigger actions if that is the
case. If I understand correctly, I cannot use the Port class from
ofproto_v1_3_parser.py to get the link status, like this e.g.:
@set_ev_cls(ofp_event.EventOFPPSLinkDown, [MAIN_DISPATCHER])
If someone would just tell me where to find this information, that would be
much appreciated.
Best regards,
Marko
