Is there a tool/utility which will let me configure a sample network in the tool? I would like to make sure that I configure the sample/test network in the tool/utility before moving into a production setup.
The idea is to put all the switches and routers into the tool/utility. Assign all the IP addresses, VLANs... and for the tool/utility to tell me if I setup the network properly. That way when I setup my network at the clients I will know exactly what do to.
