Abstract

It is often difficult and time-consuming to manage computer 'moves, adds, and changes' that take place in a switched, subnetted environment. It is even more difficult when the accepted network policy requires that a computer be configured and always connected to the network on a specific Virtual LAN (VLAN) based on its usage. An on-going problem is to keep all of the network host information up-to- date, and to ensure that hosts always land on the correct subnet when they are plugged into switch ports. Utilizing some freely-available tools, as well as some home-grown software, we have built a system that automates a number of the tasks associated with moves, adds, and changes.
