Of all the tips you've published, I think that this could be the most useful yet. If it does everything you say it does, it will be an indispensable tool for anyone doing work on Cisco gear.
hi guys, I downloaded the cisco emulator and unziped to my destop, now I need some help installing it on my pc. Do you have any installation instructions.
Hello dion2herrera,
I need help also, have you figure out on how to get it configure? If so can you help me too?
Thanks,

I've been running this for about a month / month and a half and I've found that with 1.5GB of RAM I can run 3 routers at once, 4 if I don't mind slowdown. Once you go over that your system is garbage ... i.e. make sure you allocate enough resources for your testing.
Also, I've found that on Windows you may want to go in and set the Dynamips process to Low Priority in Task Manager, this way when it hits 99% CPU utilization you can still use your PC.
Other than that, the emulator does exactly what David has stated, it's an excellent tool. Also, not sure if he mentioned it, you can INTERFACE WITH YOUR REAL NIC to attach it to a real world network to test Internet functionality.

Have you tried to calculate the idle values in GNS3? This way the routers don't consume all your resources when idling.
If not, read the documentation provided with GNS3 to calculate these values.

Yeah, I've run the Idle Values and put them in, but my CPU still goes up to 99%. I found it easier just to remember to lower the priority than spend time figuring out why the Idle Values aren't working (which I've posted on their message board and many other are having the same problem).
It a few months on now. Are you still using the emulator and have you sorted the idle pc values problem?
Thanks for the post, I will give a try.
Personally, I use Packet Tracer 4.1 which is quite good except you can't do debug and couple other things.

I have been using Packet tracer , hope this will be more advanced to use.
Keep it up i always enjoy your write up

Cisco has the new packet tracer 5 and works great. I have a whole network setup right now with ip phones, fiber, printers, etc. The server modules will even do DNS, DHCP, and Web Servers. Great product.
Hi, I'm using tool from http://amuware.com there is able add PIX device into topology, Tom G
This rocks! Free tools, especially ones that that work are always a great thing!
The screen shots show routers using serial connections, but GNS3 doesn't support wic modules.
How was a serial connection accomplished??

How can i get cisco IOS image to use with this emulator?
i have downloaded the graphical network stimulator and loaded in my computer but i am not understanding how to use it and how to configure it .please give details information.
go to http://www.gns3.net/documentation and check out the GNS3 video tutorials section.
I have begun posting my own GNS3 labs at http://www.gns3-labs.com .. All nice and in order. Hopefully this helps others 
I just started using this tool on my PC and MAC...very nice. The install and setup
was easy. Just have your IOS image(s) and away you go. Wonderful if you cannot
afford real hardware. Can be memory intensive.

How is this "perfect for a CCNA student" who has no access to IOS images?
Have you tried online router simulators?
They don't require downloading, installing, and Cisco IOS images, so are perfect for CCNA students.
Here is one http://www.internetworktraining.com/labs.aspx

it is a good project i thing that if all network engineer have a this knowledge that its project is very femous and develop.
Do you need to get IOS Images? Where can you get them from? I have a CD that came with my Cisco CCNA book. It has Router Simulations, but only for labs. I want a simulation where I can do whatever I want and just play around, not what the lab tells me.
If the images are copyrighted are there open source clones that aren't copyrighted by Cisco, but do the same thing and are legal?

you WILL need images, but if you have cisco routers, you can upload them via tftp to a server and use that location with gns3
A good tool is amuware also, it is GUI interface for dynamips and pemu PIX:

When I try to download GNS3 windows complete package I receive warning from McAfee that the software (GNS3) contains potentially harmful spyware or Adware. What it in this download to cause that warning? I aborted the download to be on the safe side.
What is Cisco's stance on duplicating images [even though you own the machines] for purposes other than backing up the routers? I would assume it would be hard for them to sue someone who has 1 copy in storage, even though it can be accessed by a non-Cisco product. That's a big concern at the school I teach at.
Packet tracer belongs to Cisco and it's my understanding they don't like [as in sue the daylight out of] anyone who isn't in the Cisco Academy or an alumnus/a of one.
Can anyone asist me. my machine is freezing when i try to press the play button on GNS3, it taking for ever long to go into the simulation mode.
What could be wrong? It has 1.93 Gig RAM and 160 Gig drive with 120 free space

There are many Cisco Lab Simulators available in market for practice CCNA and CCNP Labs. Please find below link...

Well i
I downloaded the GNS 3 package to study for CCNP, it launches fine. I can actually configure routers 1 and sometimes router 2, the only question I have is.
Why does it loose connection with the default server and never reappear? The message I get are
Router 1 connection lost with 127.0.0.1:7200
Router 2 connection lost with 127.0.0.1:7200
Router 3 connection lost with 127.0.0.1:7200
I believe these are the pre-established IP and port addresses for the software, I have asked for clarification of this problem from the GNS 3 team, but I am still awaiting an answer. It does not matter how many times I uninstall and re-install it I still get the same messages when I try to run it. Anybody got any ideas out there as to how to resolve this matter?
