Many users search for “i86bi-linuxl2-adventerprisek9-m-152-may-2018.bin download”, but free public download links are almost always illegal. Here’s where to get it properly:
Cisco Modeling Labs (CML) / VIRL
GNS3 Marketplace/EVE-NG Community
Older Lab Bundles (if bought from eBay/lab sellers)
If you’re a student, check if your institution has a Cisco Networking Academy agreement – they may provide access.
Solution: In EVE-NG, change the console type from telnet to vnc or adjust QEMU line to include -nographic.
For EVE-NG:
# 1. Upload image to correct directory
/opt/unetlab/addons/iol/bin/
If you cannot obtain the May 2018 binary, consider these legal alternatives:
| Image Name | Best For | Resource Use |

Additionally, you can use Cisco CML (formerly VIRL) which provides a web-based GUI and includes this exact image in its default image library.
