Network Switch lua file

Greetings to all !
I'm looking for retreive the lua file of the Network > Switch section of the Luci interface.
I searched everywhere via SSH.. I found some others one... but not this one.
I want to start a new page from this .lua page (cbi code)
If also you have some example/tutorial for use the CBI (
Thanks for your help

Have you checked /usr/lib/lua/luci/? Everything there is organised into MVC, you may want to look under /usr/lib/lua/luci/*/admin_network/

Thanks.. Sorry, since I found it !

For the others and for information, I finnaly started from the samba.lua file as example.
