Hi. I am making OpenFlow testbed with 2 NetFPGA switches and 3 standard PCs with Stanford Reference design installed on it. I successfully installed OpenFlow v1.0 switches on NetFPGA, and network works just fine without flowvisor (I used l2_learning and spanning_tree scripts). But, when I connect switches to flowvisor and run l2_flowvisor and openflow.discovery scripts disaster begins. I get errors like this for every switch:
type: OFPET_BAD_REQUEST (1) code: OFPBRC_BUFFER_UNKNOWN(8) That's not all. When I turn off flowvisor and connect switches on POX controller again, NetFPGA switches (software switches do) don't work!!! They manage to connect to controer, receives packet but when instruction form controller arrives they do nothing, and flow table remains empty. When I first time had this problem, I installed OpenFlow on Netfpga again, switches recovered but flowvisor again distroys everything. I realy have no idea how to explain this, so please help! I will be greatfull for every suggestion. Also,maybe I should mention that I used flowvisor before but on topology with two swtiches only (one software and one NetFPGA) and that was working well. But I didn't have loops in topology then, so I only used l2_learning script. Thanks in advance!
