Hi All, This is regarding the add-flow command using dpctl for userspace switches. The setup is based on Openflowvms, Openflow1.0 based switch and nox controller. A virtual network topology of three hosts connected to a switch is generated. Ping between hosts is successful. The OF protocol messages between the switch and the controller is verified using wireshark.
However when we attempt to look into the flow table of the switch using dump-flows command, no entries are found. The following message is displayed, * qemu:/cdrom# ./dpctl dump-flows unix:/var/run/dp0 stats_reply (xid=0x757be3e2): flags=none type=1(flow)* *It is made sure that the flows are not expired when the command is given.* Also the flows added by dpctl command has no effect on the switch functionality. Do let us know if addition/modification/deletion of flows via dpctl commands has any dependency on the activity of the controller for userspace switches. Kindly help us to resolve this issue. Thanks, Raghu
