Hi Joe , I would prefer to use 3725 and 2600 in the simulation , where router 3725 can simulate a switch ( when you add NM-16ESW module ) , it is not really a switch but can support " switchport" commands .
I am using windows XP ( Ram 4 GB / CPU AMD 4x ) and by idlepc it gets around 20% of CPU . Also, serial interface works fine but the issue of falling asleep is coming up occasionally. Advice: if you have time to spend in preparing GNS3 that would be good , I have waited 2 weeks long trying to prepare it . You may also check something called " rednectar GNS3 workbench " someone prepared a workbench on Ubuntu .

The draw back is that there are certain features that aren't available on older code. The only routers that will run the latest code are the 7200's. I've found them to have the falling asleep issue that you mentioned. I recently spent about 4 days straight trying different IOS versions and idlepc values but still no dice. I'm persevering with dynamips as I'm hopefully near the end of the road but if I had my time again I'd find a way to get hardware. I have wasted countless hours on issues related to Dynamips/lab setup. Oh, I found I had to remove the scheduler command from router configs in order to get a stable setup. Before I did that my routers were falling over constantly. I haven't had any issues with serial interfaces. Hope that helps. cheers, Ben.

I am using Dynamips with GNS3 on Kubuntu/Ubuntu 11.10 Linux, with the IPExperts labs I have some questions on how people are running some of the labs like VOL1 with GNS3? Have you encountered issues with serial interfaces not coming up and staying up with or without a clockrate applied to the applicable serial interface? Routers falling asleep even though the IdlePC, Idlemax idlepc are appropriately set and overall CPU usage is approximately 60% with all devices active? What IOS's are people using? AIS or AES? cheers Joe _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
