What command will display the line, protocol, DLCI, and LMI information of an interface?

The command that will display the line, protocol, DLCI, and LMI information of an interface is related to the specific type of interface configured on a device, particularly for Frame Relay interfaces. The correct answer effectively provides detailed information about the status and configuration of interfaces, capturing essential metrics that are crucial for network diagnostics and monitoring.

When using the command that corresponds with the correct choice, it showcases information related to the connection details which include the physical and logical status of the interface. Specifically, it outlines the protocol status, which informs the user whether the interface is operational, as well as DLCI (Data Link Connection Identifier) which designates the virtual circuit being used, and LMI (Local Management Interface) details that assist in the management of Frame Relay connections.

This command is comprehensive compared to other candidates, as it is standard practice in networking to utilize such commands to gather a full picture of interface health and configuration settings.
