Stability: The 15.4T train is generally considered stable and robust for complex simulation scenarios. 4. Implementing in GNS3: A Step-by-Step Guide
To use this image, you must have GNS3 installed and the IOL image file located. Step 1: Create the IOL License File (iourc)
IOL images require a license file named iourc to run. If you don't have one, the switches will refuse to boot. The content generally looks like this: [license] Use code with caution. Meaning: Intel x86 architecture running Cisco IOS on Linux
Note: This license is usually generated based on the hostname and domain name of your Linux GNS3 appliance. Step 2: Add IOL Image to GNS3 Open GNS3 and go to Edit > Preferences. Navigate to IOU Devices > IOU Images. Click New.
Browse and select i86bi-linux-adventerprisek9-ms.154-1.t-antigns3.bin.
Set the type to Switch (since it is a multilayer switch image). Ensure the IOURC path points to your iourc license file. Step 3: Run the Device
Drag the new IOL switch into your workspace and start it. If it fails, check that the iourc file is correct and that the file permissions allow execution (chmod +x). 5. Troubleshooting Common Issues
Switch Crashes/Reloads Instantly: This is almost always a licensing issue. Recheck your iourc file content and hostname/license key match.
High CPU Usage: Even though IOL is efficient, running too many instances can spike CPU. Ensure you have properly configured idle-pc if necessary, though this is less crucial for IOL than for Dynamips.
Layer 2 Issues: If VLANs don't work, ensure you are using the correct command vlan database or vlan depending on the specific subversion of the IOL image. Conclusion
