Is there a wiki which explains switch configuration ?
What does it mean that they are treated as normal interfaces ?
Is it possible to open socket and send/recieve on switch ports (lan0

My understanding is that these ports are not treated the same as eth0
interface for example.

Thanks for the assistance,
