I don't understand that sentence. > When we are mentioning openflow13 in the command as in "ovs-ofctl -O > openflow13 diff-flows br0 <Filename>", then the output received contain > only the flows written in the file with a plus or minus sign i.e. it is > dumping only the flows of the file and not compairing with the flows on > the switch which it should ideally do. I don't fully understand that sentence, either, but it sounds like you are reporting a bug. I appreciate bug fixes. > Query 1: What is the significance by mentioning openflow13 in the > ovs-ofctl -O openflow13 diff-flows br0 <Filename>. This instructs ovs-ofctl to use OpenFlow 1.3 to talk to the switch. > Query 2: When we are adding a flow using default standard (that is not > including importance in the flow) and adding the flow in the file having > importance, then using "ovs-ofclt diff-flows br0 <filename>" we are > getting difference in each flow as the file contains importance and the > flow in switch does not.

If the flows in one place have importance (other than the default importance) and those in another place do not, then I would expect every flow to differ. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
