You need do have some component(s) that will install flow entries on the switch for the ping to go through have a look here: http://noxrepo.org/noxwiki/index.php/FAQ#What_does_the_traversal_of_a_packet_through_a_NOX_controlled_network_look_like.3F 2011/4/26 linbo <li...@csnet1.cs.tsinghua.edu.cn> Hi ，all I want to verify the openflow and controller work well or not，but I get something wrong. here is my problem: 1、the openflow switch has connetected to nox ，and the topology is as follow： openflow-controller:eth0 -> 192.168.1.1/24 openflow-switch:eth0 -> 192.168.1.2/24 openflow-switch:eth1 -> no IP (would act as a switch port) openflow-switch:eth2 -> no IP (would act as a switch port) openflow-host1:eth0 -> 192.168.2.1/24 openflow-host2:eth0 -> 192.168.2.2/24 2、when i ping host1 from host2 ，I can‘t see any ping replies coming. i check out the flow table of the switch ，and the flow table of the swtich is empty。 so how can I add a flow entry through nox to the openflow switch to let the ping work welll Thank you！ 2011-04-26 linbo _______________________________________________ nox-dev mailing list nox-...@noxrepo.org http://noxrepo.org/mailman/listinfo/nox-dev
