CLI Overview


Command Line Interface is a user-friendly interface. It is mostly used in network device management. Using Command Line Interface, user can easily communicate to any component in a computer, hardware device, network device, operating system, and other applications.


Despite advances in network management technologies and the advent of other popular management protocols, such as SNMP, there are still numerous devices in the network, which offer CLI as the only way or preferred way of managing them. Also CLI-based configuration tasks have been simplified using scripts. Thus it has become by far the most prevalent management connectivity in the world. After the popularity of the Internet and IP networks, the CLI protocol was offered not only on serial links but also over TCP and other transport protocols. This offered a lot of flexibility to CLI users who could still use the same CLI command from a remote terminal to manage the device instead of being tied down to a terminal connected to the device over a serial link. These management terminals (remote and local) gradually came to be known as 'Management Console' or 'Management Stations'.
