Hi all: I am using Flowvisor v1.4 to connect a Ryu controller and a NEC PF5240 physical openflow switch. Ryu controller can INSERT/DELETE the flowentry of the switch but cannot GET the flowentry from the switch (It cannot MODIFY flowentry, either. Because it seems that it's an unimplemented flowMod.modify) When Ryu tried to GET the flowentry, it received an empty value in the response body which means Ryu got nothing. When I looked into the log of Flowvisor, it showed "*flowvisor: WARN classifier-dpid=00:00:00:00:00:00:00:06 : Dropping empty stats reply: ofmsg:v=1;t=STATS_REPLY;l=12;x=273;st=PORT*" However, the flowentry did exist when using the command "*fvctl list-datapath-flowrewritedb conA 6*" to check in Flowvisor. And I changed the switch to a physical Pica-8 openflow switch and the mininet as well, it worked fine and can GET/INSERT/DELETE the flowentry.
Is there anyone who had the same experience as I did? Thanks~~~ ----------------- Best Regards, Sylar Shen
