1028 CHAPTER 83: BASIC CONFIGURATIONS
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:
■ Hierarchical command protection where you can only execute the commands
at your own or lower levels. Refer to “Configuring User Levels and Command
Levels” on page 1026 for details.
■ Easy access to on-line help by entering “?”
■ Abundant debugging information for fault diagnosis.
■ Saving and executing commands that have be executed.
■ Fuzzy match for convenience of input. You only need to input the characters
that can uniquely identify a keyword to recognize and execute the keyword.
For example, for the keyword Ethernet, you only need to input eth when you
execute a command with this keyword.
