Hi all,
I am a newbie in developing an application using Ryu.
Since I have added extra functionality to my openflow 1.3, I need the
controller app send the feature request to the switch to inquiry about the
new added feature.
But by running
@set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER)
def switch_features_handler(self, ev)
def send_features_request(self, datapath):
ofp_parser = datapath.ofproto_parser
req = ofp_parser.OFPFeaturesRequest(datapath)
datapath.send_msg(req)
event and event hander, It seems by default ev.msg return:
switch features ev version: 0x4 msg_type 0x6 xid 0x2e11eb2e
OFPSwitchFeatures(auxiliary_id=0,capabilities=79,datapath_id=1,n_buffers=256,n_tables=64)
As I debuged my switch, msg feature request is not sent by controller to
switch for new capabilities.
I have to imply that new capabilities has been added enum ofp_capabilities
in
ofproto_v1_3.py<https://github.com/osrg/ryu/blob/master/ryu/ofproto/ofproto_v1_3.py>
Is there any default event generator in ryu that generate this event
without asking from the switch.
any help is appreciated in advance
Hanieh.
