Catalyst Switch
User-Submitted Article
This article talks about the basic configuration of a Cisco Catalyst
switch. Use these commands when you get a new or used Cisco switch that
you want to configure. These commands will work on pretty much any
Cisco catalyst switch. When you get a new or used switch, the first
thing you will have to do is connect to it. Normally, this is done by
using a laptop and a console cable. I assume if you are looking for
these type of instructions that you can do already do that. Once you
are able to connect into the switch, you can begin configuring it.
