Troubleshoot (like "license not found" or "libcrypto errors").

Fix permissions via the EVE-NG CLI using the command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Create your iourc license file in the same directory. 3. Integration in GNS3 To add it to GNS3:

: Represents the "Advanced Enterprise" feature set, including strong crypto ( k9 ) for secure management protocols like SSH and HTTPS.

To use this image, you typically need a network simulator and a license key file ( Using with GNS3 Ensure the i86bi-linux-l2-adventerprisek9-15.2d.bin

: If your nodes boot up and immediately shut down, or if text states your license is invalid, double-check your iourc file configuration. The hostname of your Linux VM must match the string used to generate your IOL license key.

Target platform and deployment models

: Link aggregation via Port Aggregation Protocol (PAgP), Link Aggregation Control Protocol (LACP), and static bundling.

GNS3 utilizes the GNS3 VM (running Ubuntu) to host IOL images. Go to .

: Advanced service provider features like QinQ (802.1Q tunneling) or Private VLANs can be hit-or-miss or behave unpredictably compared to physical Catalyst hardware or official CML images. interface Ethernet0/1 switchport mode trunk
