LAVI:Miscellaneous

From OpenFlow Wiki

Changing the TCP/SSL Port

The default TCP/SSL port can be changed in jsonmessenger. We can also change it as the command line when we invoke NOX. For example,

./nox_core -i ptcp:6633 jsonmessenger=tcpport=11222,sslport=0 lavi_switches lavi_swlinks

will run TCP server on port 11222 and SSL server will be disabled.

nox-console.py

nox-console.py is written as the console for NOX. This tool polls LAVI for information about the network, esp. for situation where a graphical display is lacking or when bandwidth is very limiting. The options and command line arguments that can be listed using

nox-console.py --help

This is a good starting point.

Extending LAVI

Extending LAVI is the same as using jsonmessenger or messenger in NOX to handle messages. This can be done by registering for the JSONMsg_event, for which sending function are carried by the Msg_stream class contained in the event. Generic JSON dictionary/message can be sent and received. These messages are parsed before being passed along using the event.
