CISCO PacketTracer is a brilliant CISCO lab simulator for those wanting to learn how to configure and maintain CISCO kit, or run simulations.
Or as the CISCO site says;
Packet Tracer is a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions. As an integral part of the Networking Academy comprehensive learning experience, Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts.

You can download it from either the CISCO Network Academy, or from here.

thanks for this, I’ve been searching all over for this. Found this through your comment on youtube.
Thank’s, good program.
lol, cranky bitch. if you put something up for the public don’t expect people to adulate you. you should be doing it for your own sense of betterment of the community. I’m not going to beg to get a download link, and it frankly disgusts me that you would ACTUALLY REQUEST that people say nice things to you.
In reply to pitcher:
I think you missed the point – and I bet you didn’t think I’d approve this comment! I’m not expecting adulation, but I guess I should spell it out.
If someone gives you something, what do you say? Even when you buy a cup of coffee, you say something to the person that serves you… It takes about 5 seconds to say thank you, and in that light I thank you for your comment – you’ve reassured me that I did the right thing to take the link down.
The majority of internet users take too many things for granted, I count you in this category. I wonder, would you have bothered to comment at all, if the link was still up – my money would say no.
Keep taking things for granted my friend, and thank you once more for your comment. Politeness, goes a long way
Thanks pal.
