Hi list,
1. On your wiki, you mention that you plan to replace dpset with topology.
What's the status now? Is topology usable already? And if yes, how to
replace a line like:
@handler.set_ev_cls(dpset.EventDP, dpset.DPSET_EV_DISPATCHER)
with topology?
2. in the OpenFlow example on the wiki, you use the following handler
line:
@set_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
Also, several scripts in the ryu source code use
ofp_event.EventOFPPacketIn.
However, I cannot find it defined anywhere in ofp_event. Why?
3. If I use my script, which works perfectly fine with OF 1.2 and want to
test it with 1.3, the
@handler.set_ev_cls(dpset.EventDP, dpset.DPSET_EV_DISPATCHER)
actually causes an exception:
hub: uncaught exception: Traceback (most recent call last):
File

"/usr/local/lib/python2.7/dist-packages/ryu-1.9-py2.7.egg/ryu/controller/dpset.py",
line 164, in switch_features_handler
datapath.ports = msg.ports
AttributeError: 'OFPSwitchFeatures' object has no attribute 'ports'
How to fix this?
Cheers and Thanks!
