How To Save Configurations in EVE-NG Using Startup Config

If your lab is working correctly but your configurations disappear after restarting or reopening the lab, you may need to use EVE-NG’s Startup Config feature.

This feature allows EVE-NG to save and reload your device configurations automatically.

Step 1: Configure Your Device

Make your changes as usual.

Example:

• Set hostnames
• Configure IP addresses
• Create VLANs
• Configure routing protocols

Step 2: Save the Configuration on the Device

Before exporting anything, save the running configuration on the device.

For Cisco devices:

write memory

or

copy running-config startup-config

Step 3: Export the Configuration in EVE-NG

After saving the configuration:

1. Right-click the node.
2. Select Export Config.
3. Wait for EVE-NG to export the configuration.

This step creates the Startup Config file used by EVE-NG.

Step 4: Verify Startup Config Is Enabled

Open the Startup Config panel in EVE-NG.

If the export was successful, the node should show ON under Startup Config.

When enabled, EVE-NG can automatically restore the exported configuration after a node wipe or restart.

Important

Saving the configuration on the device is not enough.

You must also export the configuration using EVE-NG’s Export Config feature.

Without exporting, EVE-NG cannot restore the configuration after the node is wiped.

Returning a Device to Factory Default

If you want the device to boot with a clean configuration:

1. Erase the startup configuration on the device.
2. Turn the Startup Config option OFF in EVE-NG.
3. Restart the node.

The device will boot with the default factory configuration.
