I needed to do some quick switching labs so I run IOU Layer 2 Switch in VirtualBox and GNS3. To run an IOU Layer 2 image in GNS3, go to File > Important Appliance > search
the IOU .ova file > Next.
You can delete image files from the IOU VM server by issuing the commands (Linux):
cd /home/gns3/GNS3/images/IOU // CHANGE DIRECTORY
ls // TO LIST
rm <IMAGE NAME> // REMOVE THE FILE
You'll need to allow GNS3 server on your PC personal firewall (mine's Windows Firewall). Click Allow access.
Click Import.
To edit settings, click the IOU VM > Settings
General > change the VM name (IOU_VM)
System > Motherboard > Base Memory > type 256
Network > Adapter 1 > Attached to:
Host-only Adapter (this settings is already pre-configured) > click OK.
Right-click on the VM > Start > Normal
Start.
Type the login and password: root / cisco
I had an issue where there was no IP address after http://
To fix the blank IP address, go to File > Preferences > Network > Host-only Networks
> VirtualBox Host-Only Ethernet Adapter #x > Adapter > Edit (screw
driver icon at the very bottom).
Go to DHCP Server tab > leave Enable Server ticked > type Server Address:
192.168.56.100 > Server Mask: 255.255.255.0 > Lower Address Bound:
192.168.56.101 > Upper Address Bound: 192.168.56.254 > click OK.
Reset the IOU VM by doing a Power OFF then ON. You'll notice the http:// has an IP address upon bootup.
You can also verify using the ifconfig
command.
Type the URL http://192.168.56.101:8000/upload on a web
browser (I’ve used Mozilla Firefox) > click Browse and search for the IOU file >
click Upload.
Upload the L2 and L3 IOU Images (compatible with GNS3 1.3.1rc4) and also Phyton license setup
The upload process will take about 2-3 minutes to finish.
You can delete image files from the IOU VM server by issuing the commands (Linux):
cd /home/gns3/GNS3/images/IOU // CHANGE DIRECTORY
ls // TO LIST
rm <IMAGE NAME> // REMOVE THE FILE
In GNS3 (I've used version 1.3.1rc4) go to Edit > Preferences > Server > Local
server tab > choose host binding:
192.168.56.1 and TCP port range below.
Go to Remote servers tab > leave the defaults for Host:
192.168.56.101 and Port: 8000 TCP > click Add > Apply.
You'll need to allow GNS3 server on your PC personal firewall (mine's Windows Firewall). Click Allow access.
Go to IOS on UNIX > Browse > search for the IOURC.txt
file > click Apply.
Click IOU devices > leave the default settings below and
click Next.
A pop-up message will appear asking to provide the directory
path of the IOU Image (IOU Image URL can be found on the web browser/server)
> click OK.
Type a Name (L2 Image) > copy/paste the IOU L2 Image
directory (/home/gns3/GNS3/images/IOU/i86bi-linux-l2-adventerprisek9-15.1a.bin) > leave default Type of L2 Image > click Finish > Apply >
OK.
Click and drag the L2 Image switch icon > right-click >
Start (or click Start green icon on top) > right-click again > choose
Console.
