Waleed,
I set the idlepc idlemax parameter in the console window at the bottom
of the GNS3 window like this
idlepc idlemax /all 500
Ciao

Hi Joe ,
I have used it but I prefered to use XP version , I just suggested
that you may like to use linux .
I think linux & windows are the same in my trial for GNS , but most
important IDLEPC value .
You can get the idlepc value as following:
- Run R1 , then get the idlepc value for CPU , I got it at 5% , then
copy and past it to all use command " idlepc copy R1 all"
- Run BB1 ( 2600) and do the same step above.
- run the rest of the devices in delay ( wait a time between each one
) , you will see cpu gets high and then backs to low , this is the
time to run the other device.

Have you used the RedNectar at all?
It looks promising and what I would end up doing is using the
IPExpects files to create that I need.
Ben
Thanks for the info on the scheduler command.. I hadn't thought of
that..
The reason I went to using Kubuntu is due to feedback from people that
stated Linux was the way to go with Dynamips with GNS3 as the front end.
Now that I have more under my belt with idlepc idlemax and some other
commands, I may hack the set- up from IPExperts to get smaller routers
(different hypervisor) used in place of 3725..
Cheers
Joe

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 .

Hi Joe,
I found that I was able to get a stable lab using 2961 routers in
dynamips running 12.4(9)T7. 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.

Subject: [OSL | CCIE_RS] Dynamips & IPExperts .NET/Labs
Hi Guys
I followed with interest the various conversations of Dynamips. 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
