CLI login
Overview
The CLI enables you to interact with a device by typing text commands. At the CLI, you can instruct your
device to perform a given task by typing a text command and then pressing
Enter
to submit it to your
device. Compared with the graphical user interface (GUI) where you can use a mouse to perform
configuration, the CLI allows you to input more information in one command line.
You can log in to the device at the CLI through the console port, Telnet, SSH, or modem.
•
By default, you can log in to a device through the console port without any authentication, which
introduces security problems.
•
By default, you cannot log in to a device through Telnet, SSH, or modem, so you cannot remotely
manage and maintain the device.
Therefore, you need to perform configurations to increase device security and manageability.
Logging in through the console port
Introduction
Logging in through the console port is the most common login method, and is also the first step to
configure other login methods.
By default, you can log in to a device through its console port only. After logging in to the device through
the console port, you can configure other login methods.
