CLI stands for Command Line Interface and TL1 stands for Transactional Language 1. Well, let we first clarify that it is wrong to say that there is a difference between CLI and TL1. Then why we kept the title that says so? Well, we have lot of readers coming in searching for difference between CLI and TL1 and we wanted to ensure that they land here and see the information provided for their benefit…!!

Okay, fair enough, what we would like to call it as? We would like to call it as – TL1 exposes CLI. Let us now understand how.

CLI is a text-only interface where an operator/user enters a command in terminal to perform certain task and upon completion the result is returned in the form of text lines and is displayed on same terminal. CLI is a type of interface. GUI (Graphical User Interface) is another type of interface that allows user to perform operation using mouse or pointers. MS-DOS & Unix Shell (bash, ksh etc.) are very well known examples of CLI.

TL1 is a widely used management protocol in telecommunications. It standardize the interfaces for managing a telecommunications or network device from a console/terminal. Network devices that implement TL1, they expose a command line interface for operator/user to interact with them. The operator/user can enter a command in the terminal to perform certain operation on network device.

To summarize, CLI is a type of interface that allows user to perform operation by entering commands where as TL1 is a management protocol that exposes a CLI for operator/user to interact with network devices.
