I can try the patch.
And I also provide you with the details but I am not sure whether it causes
this.
I want to use ryu.topology to find switches entering in the network. I am using
Open vSwitch 2.4.0.
So I use the following code
from ryu.topology import api as topo_api
from ryu.topology import event as topo_event
@set_ev_cls(topo_event.EventSwitchEnter)
def _switch_enter_handler(self, ev):
# self.datapath_ip = {}
for sw in topo_api.get_all_switch(self):
if sw.dp.id == ev.switch.dp.id:
console.info("enter a switch with attributes datapath -
"+str(sw.dp.id)+" and ip - "+sw.dp.socket.getpeername()[0])
Every time I start the app, it shows me that warning.
Thank you!

Datapath#ports
Hi,
The warning mean that Datapath#ports is not recommended to use directory.But
the warning should not be appear in this case.Because perhaps you just use
ryu.topology.
I found out the code of the cause. This should be
suppressed.https://github.com/osrg/ryu/blob/v3.29/ryu/topology/switches.py#L545
I can make a patch to resolve the issue but I don't know how to hit the above
line.My environment don't show the warning. (Mininet w/ Open vSwitch)Can you
confirm the patch instead of me?Or please give me more details. (e.g. product
name of your openflow switch and your procedure)
Regards,Satoshi

Hi,
I got warning with
"/usr/local/lib/python2.7/dist-packages/ryu/topology/switches.py:545:
UserWarning: Datapath#ports is kept for compatibility with the previous
openflow versions (< 1.3). This not be updated by EventOFPPortStatus message.
If you want to be updated, you can use 'ryu.controller.dpset' or
'ryu.topology.switches'.
for port in dp.ports.values():"
I found this message coming from /ryu/controller/controller.py
The constraint causing this is "ofproto.OFP_VERSION >= 0x04"
Does it mean that if I am using openflow 1.3, the warning message will trigger
all the time?
How can I get rid of this?
Thanks.
