"Cisco's Packet Tracer is a network emulation program that is limited as far as router and switch commands go, but is all you need to study for your CCENT/CCNA. This is also a cheaper option than buying your own physical switches.
PS - you have to have been enrolled in Cisco's Network Academy at some point in time to be able to download it. If you decide to check out the program private msg me."
Thank you for reply. I would love to get inside on that simulator. I do have a lite version(that came with the book) but not much of configuration you can do on it. 2950 is not that expesive about 30 bucks.
I see you are a network engineer-this is what's my passion. Can you give me couple insides on how did you get there and what was your path?
