Hello,
After some more investigation, I find out the problem in in this line
match1 = parser.OFPMatch(ipv4_dst="10.0.0.5”)
Can anyone tell me what is the correct format to set the ipv4 address? In the
documentation it only mention its format is a IPV4 address. I also failed to
find work code to set IPV4 open flow rules in rye online.
Thank you!
