Chapter 1. Using the CLI
Overview
This chapter describes how to start using the CLI and the CLI command editing features.
CLI Command Modes
Introduction
To assist in configuring the device, the Command Line Interface (CLI) is divided into different command modes.
Each command mode has its own set of specific commands. Entering a question mark "?" at the system prompt
(console prompt) displays a list of commands available for that particular command mode.
From each mode a specific command is used to navigate from one command mode to another. The standard
order to access the modes is as follows: Privileged EXEC mode, Global Configuration mode, and Interface
Configuration mode. After logging into the device, the user is automatically in Privileged EXEC command mode
unless the user is defined as a User EXEC user.
The User EXEC mode can be assigned for a user once a user account is created. Only a limited subset of
commands are available in User EXEC mode. This level is reserved for tasks that do not change the configuration.
To enter the next level, the Privileged EXEC mode, a password is required.
The Privileged EXEC mode gives access to commands that are restricted on User EXEC mode and provides
access to the device Configuration mode.
The Global Configuration mode manages the device configuration on a global level.
The Interface Configuration mode configures specific interfaces in the device.
User EXEC Mode
In general, the User EXEC commands allow the user to perform basic tests, and list system information.
The user-level prompt consists of the device host name followed by the angle bracket (>).
The default host name is Console unless it has been changed using the hostname command in the Global
Configuration mode.
Privileged EXEC Mode
Privileged access is the system default mode and is password protected to prevent unauthorized use because
many of the privileged commands set operating system parameters. The password is not displayed on the screen
and is case sensitive.
Privileged users enter directly into the Privileged EXEC mode. To enter the Privileged EXEC mode from the User
EXEC mode, perform the following steps:
1. At the prompt enter the enable command and press <Enter>. A password prompt is displayed.
