Check the mac address of switche s1, only switch can send packet_in message to controller 2. If your switch's mac address is something else, do a clean up of your mininet network by cmd: sudo mn -c and try again. 3.Also note that, start your controller first, start mn next. ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
