Re: [nox-dev] Help with NOX to OpenFlow messages
OpenFlow version 2.02 doesn't mean anything to me. What kind of switches are you using? What IP address are you using with dpctl? The switch? In general, switches make active connections (they initiate a connection to the controller/NOX), so it's not listening on port 6633. Sometimes switches can also be configured to listen too, but it depends on the switch and on the configuration. More to the point, you say that you're trying to get NOX to send messages to the switch, but dpctl doesn't have anything to do with that. Have you configured the switches to connect to the IP that you're running NOX on? If you run NOX and set it to listen for connections, do the switches connect? What commandline are you running NOX with? -- Murphy On Feb 28, 2012, at 3:11 PM, Elias Marti Paz-Rudolph wrote: Hello, I am in the beginning stages of implementing an OpenFlow network.

Re: [nox-dev] Help with NOX to OpenFlow messages
This sounds like a switch configuration issue; you might try whatever support channels HP provides. Is NOX configured to listen for connections on whatever port you set the switches to connect to? -- Murphy On Feb 28, 2012, at 3:36 PM, Elias Marti Paz-Rudolph wrote: I am using HP ProCurve 3500 yl switches. i have configured the switch to listen on port 6633.

Re: [nox-dev] Help with NOX to OpenFlow messages
In order to configure the listener port on the HP you should do something like: openflow vlan listener ptcp:port Then you should be able to dpctl the switch. Though a word of warning, now everyone else can too :P .

Re: [nox-dev] Help with NOX to OpenFlow messages
Why would you think you could ssh to the controller on that port? Do you mean you can't dpctl that? You should be dpctl'ing the switch not the controller.
