Hello,
The questions you are asking, are simply too vast too answer in a simply post.
You best bet is to buy a Cisco book in regards to ICND 1 & 2. If you are familiar with the theory between network and just want to see the commands in practice I suggest you download packet tracer from net academy. Also if you go to YouTube and search for Dan course, he will walk you through running commands in packet tracer. He covers CCNA & CCNP.
Thank you,
Carl
