To split one real port into several virtual ones, do the following:
1. Select a real port which will be split.
2. Choose virtual ports which will communicate with the split real port and add them to the bundle by clicking the "Add port" button.
3. Choose a virtual port to be set as the main one and click "Set main".
4. Click the "Add split port" button. Now, your port bundle is automatically created in the Bundle tree.
Note: If you receive an error message when creating a port bundle, you can analyze the information shown in the Activity log.
