GNS3 Hardware specs???

itdaddy

Hey guys I want to run GSN3 cause I love the GUI so you can make text descriptions
and cool topology maps..I have it installed on my laptop which has

2GB ram
duo core amd processor
and no antispyware/av running
just bare bones XP pro SP2

and man it eats up my CPU

I have tried Affinity configs and just locks up due to CPU maxed out

what hardware do i really need or what am i doing wrong?

thanks

I haven't got into dynamips very much aside from just testing with it before I just got remote power switches for my physical lab. But have you adjusted your idlepc values? If not, you will run into high CPU utilization with even a couple of routers.

Check out this thread for good idlepc values for various images:

The rest of hacki's site has a lot of other great resources for dynamips/dynagen and GNS3 as well. I do remember reading several threads when I was researching things that there were a few people getting significantly higher CPU utilization running the same configuration through GNS3 vs just dynagen.

Yea, it's your idlepc value. It'll use 100% unless you specify the value.

They have a relatively new "new users" tutorial up here: http://www.gns3.net/documentation

That'll show you how to set everything up.

wow thanks a lot cause man my laptop has some power and man 3 routers is bogging it down to a hault. i do not run any AV/AS like i said stripped down purely for GNS3

thanks so much man i missed that
will let you know how it turns out thanks men!

Put AV on to it though.

I will be using Ubtuntu 8.04 (Hardy Haron) as Linux Power Horse .I have a 64-bit Intel Machine with Quad Core 2+ Ghz processor coupled with 8Gigs of physical RAM at my disposal. This helps me run full CCIE topology on One machine (using 10+routers ) , multiple vmware instances while conserving resources at my relatively low-end Windows laptop . If you have multiple pc’s , you can add all of them into one GNS3 topology using distributed approach as shown in this tutorial. This will ease-up burden on single pc and make your labs run faster and better.

I found this guys specs off of brainbump.net.. I was thinking that GNS3 needs this kind of machine for a ccie lab full no sheeet!

wow! i want to build this for my ohme GNS3 inthe works

tiersten

It just has more RAM than most people's machine. Everything else is standard.

If he needs that much computing power to run ten routers hes doing something terribly wrong. I run about eight on a machine I have with a 1.7 ghz amd and 1 gig ram running vista. I don't use GNS3 though, just Dynagen.

Just right click a router ---> Idle PC --> Select an idle pc value = fixed

itdaddy

Javon

I will have to try that

Tiersten

you are right 64bit Quad core; I run only duo core isnt duo core only 2 CPUs
while quadcore is 4 cpus???

and yeah GNS3 networker takes a butt load of processor power...

thanks wil have to try this; thanks a lot!

Yes. Quad core isn't that unusual these days however.

Yeah my laptop is duo core.....but just from playing with IDL PC by right clicking
oh yeah I got 3 routers down even when I come back myvalues have to be recalc'd
each time i open the lab up again. is that normal cause i do the new project and
save config and it saves all my configs but i have to alwasy recalc all my IDLE PC
values is that normal..????

and what works best is i just keep doing it until my task manager perfmon say like 3 percent cpu
and it has been working take about 10 minutes for a big lab of 4 to 6 routers runnning
but i can get it lower my cpu amount ....
but I am going build me a quad core intel machine with sata drives and 1024 fsb speed
for sure. and then i will be ready. I think i can build it for 400.00 usd i think i have monitor
and kvm switch so just need the tower

power
ram
cpu
mobo
all ineed

i might do 8 GB of ram maybe or maybe only 4GB of ram

Not to hijack the thread but i thought you required a lab for the CCIE do to the stuff you perform? is the CCIE possible using dynamips?

Check out DT's post here: http://techexams.net/forums/viewtopic.php?p=198109#198109

You'll still need switches.
