I always have these idea that seem like they would be really useful and cool but just never have the time or knowledge to implement them. So why not blog about them and let some other smart dude with lots of time figure it all out.

My first idea is to have a small application that a user can fire up that will start monitoring there network connection. The program will ignore all data except cisco CDP packets. Once a packet is received then the program would be able to display what port of what switch the user is connected to. Now this might not seem immediately useful but we often find that it is useful to find out which port a user is plugged into which means having to go down a match up wall ports with switch ports. If you had a small program to do it then you've just saved yourself a trip. And it'd just be cool.
