I downloaded R&S lab demo from Internetwork Expert and created a gns3
file as included in the end of this message.
All initial config files are in position as described in the IElab1.net
OS: ubuntu 8.10 desktop AMD64
linux kernel: 2.6.28-6, ext4 file system (ubuntu 9.04 alpha)
Two problems:
(1) The routers and switches are not in the order as R1 to R6, SW1 to
SW4 and then BB1 to BB3 in the "Topology Summary" window (right side).
After adjusting the idlepc value for each router, I save the .net file
and quit GNS3.
Then I opened the .net file with plain text editor and moved the entries
in order as you can see in the IElab1.net, but when re-opened by GNS3,
they are still out of order as if I did not modify the file. What is wrong?
(2) I spent about 30 minutes to have gns3 find the idlepc value with "*"
for me. The System Monitor shows the usage all four CPU's is about 50%.
Then I saved the .net file and quit GNS3. After GNS3 restarts and
reloads the .net file, the System Monitor shows the usage of all CPU's
is 100%.
Do I need to run the idlepc every time after open a .net file?
Before this new PC, I thought the GNS3 poor performance was due to the
out-of-date old PC (not even dual-core). Now I have 45nm quad-core,
1066Mhz dual channel memory with H.T. support and 2600MHz FSB. The
calculation of idlepc value is much faster, but I do not know how to
keep the CPU usage low after restarting the GNS and reopening the data file.
In this example, there are 13 machines (6 routers, 4 switches and 3
BB's). Should each have its own value, a total of 13 different values;
or should I use one idlepc value for all devices, since they are the
same model (3640)?
Will it be better if I mix the devices with different models (7200,
3725, 3660 and 3640)?
Thank you very much for your help.
