Hi,
I found that OVS and HP use different flow tables for setting flow rules.
It's possible to determinate switch vendor? I was using mininet OVS. And
what waitress do? I tried this code:
@set_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER)
def miss_flow (self, ev):
datapath = ev.msg.datapath
desc = ofctl_v1_3.get_desc_stats(datapath)
print('desc=%s', desc.hw_desc)
In console get this error:
CONSUMES EventOFPEchoRequest
CONSUMES EventOFPPortDescStatsReply
CONSUMES EventOFPSwitchFeatures
