Question: 1 / 400

Which command is used to enable 802.1x authorization on an interface?

authentication port-control auto

Enabling 802.1x authorization on an interface is accomplished with the command that specifically sets the port control mechanism for authentication. The command "authentication port-control auto" configures the interface to automatically control access based on the authentication state of the device connected to it.

When this command is applied, the switch interface will enter a state allowing or denying access based on the result of the IEEE 802.1x authentication process. If a device connects, the switch will begin the authentication process, and depending on whether the authentication is successful or fails, the switch port will react accordingly by either granting access to the VLAN or placing the port in a restricted state.

This command is essential for implementing secure access control on a network, as it ensures that only devices that have been authenticated are granted access to the network resources, enhancing security measures against unauthorized access.
