I would like to simulate the installation of a VLAN in case this comes up at a future job I may get a contract for. As I understand it, VLANs allow you to separate individual LANs on a single switch without the need for a router in between each one.
The job I'm bidding on is a law firm with 30 or so networking devices whose cables culminate into a single server room. They also have 8 - 10 connections that belong to rooms that are being subleased to other small companies and entrepreneurs. These connections cannot be allowed access to the Law Firm's computers or servers but, as part of the sublease, they are allowed to use devices like the network printers and scanners.
The equipment they currently have is three 2960 Catalyst switches which each have 24 10/100 ports and 2x Gigabit ports. They also have an Internet connection.
Is it possible to do this with what the company has? I don't need the actual IOS commands to run, just a brief overview of how to set it up (ie, 1 VLAN for the law office computers and servers, 1 VLAN for each sublease).
