Hi All, I am working on openVSwitch with Open flow controllers. I got struck in understanding the flow of how the ovs-ofctl utility works. I am not quiet clear about how it uses the connection details(tcp:<ip>:port). What details we need to mention here. The man page says, it connects to OpenFlow switch. What component of OpenVswitch listens for ovs-ofctl commands.
I tried the following things, but it did not work. -> Configured the OVS to open flow controller where ovs-ofctl will run through ovs-vsctl. In this case I am running ovs-ofctl on the same machine. #ovs-vsctl set-controller br0 tcp:127.0.0.1:6633 -> Running the ovs-ofctl from the remote machine. Giving the connections details the machine, where the OVS is running. #ovs-ofctl show tcp:127.0.0.1:6633 -> I am getting an error saying "ovs-ofctl:connecting to tcp:127.0.0.1:6633(Connection refused)" Any help in this regard is greatly appreciated. -- Thanks & Regards, Girish
