Which command would you use to verify the status of dot1x interfaces?

1. show interfaces status

2. show dot1x active

3. show dot1x all

4. show dot1x detail

The correct answer is: show dot1x all

The command used to verify the status of dot1x interfaces is indeed focused on providing a comprehensive overview of all interfaces that are participating in dot1x authentication. When utilizing the command that displays all dot1x interfaces, you can obtain detailed information about their operational statuses, including which interfaces are successfully authenticated, which are in progress, and any that may have failed to authenticate. This holistic view is crucial for network administrators who are troubleshooting or monitoring network access control. Other commands might provide information specific to active sessions or detailed status of individual ports, but they do not deliver the complete picture across all interfaces. For instance, commands that show only active interfaces or interfaces with specific details would limit the visibility that understanding the overall status brings to managing dot1x configurations effectively. Thus, the choice that shows all interfaces participating in dot1x is the most suitable for verifications regarding status across the entire network segment involved in dot1x authentication.
