Hi all, I'm using OVSwitch with Mininet 2.1.0+ and Pox controller (Dart branch). I have a topology with 100 hosts in which 98 are attackers and perform SYN Flood attack. I'm trying to block traffic related to attackers mac addresses, to do this my controller send a flow mod with in which there is no action specified but the flow is not blocked. I've checked on wireshark if controller has sent the flow mod (it did it) and than I've also checked if the rule is installed on the flow table with a flow stat but I can't find the rule installed on the switch (that's why the traffic is not blocked). Do you have any idea of the reason why if the flowmod is sent, the rule is not installed? I supposed it could be because I have a large amount of traffic and some packets could be dropped, but I have also checked the port stats and the is no dropped packet.
Thanks -- Silvia Fichera
