Introduction to CLI
CLI is an interaction interface between devices and users. Through CLI, you can configure your devices
by entering commands and view the output information and verify your configurations, thus facilitating
your configuration and management of your devices.
CLI provides the following features for you to configure and manage your devices:
z Hierarchical command protection where you can only execute the commands at your own or lower
levels. Refer to
Configuring User Privilege Levels and Command Levels for details.
z Easy access to on-line help by entering “?”
z Abundant debugging information for fault diagnosis
z Saving and executing commands that have been executed
z Fuzzy match for convenience of input. When you execute a command, you can input part of the
characters in a keyword. However, to enable you to confirm your operation, the command can be
executed only when you input enough characters to make the command unique. Take the
commands save, startup saved-configuration, and system-view which start with s as an
example. To save the current configuration, you need to input sa at least; to set the configuration
file for next startup, you need to input st s at least; to enter system view, you need to input sy at
least. You can press Tab to complement the command, or you can input the complete command.
