Chapter 4: Understanding the Command Line Interface (CLI)
The switch utilizes Command Line Interface (CLI) to provide access to several different command modes. Each
command mode provides a group of related commands. In general, after typing a command name, always press
‘enter’ to start the execution of the command.
After logging into the system, you are automatically in the user top (user EXEC) mode. From the user top mode you
can enter into the privileged top (privileged EXEC) mode. From the privileged EXEC level, you can access the global
configuration mode and specific configuration modes: interface and Switch configuration. Entering a question mark
(?) at the system prompt provides a list of commands available for each command mode.
Document Conventions
Command descriptions use the following conventions:
• Vertical bars ( | ) separate alternative, mutually exclusive, elements
• Braces ({ }) indicate a required choice
• Boldface indicates commands and keywords that are entered literally as shown
• Italics indicate arguments for which you supply values
Access Each Command Mode
The following sections describe how to access each of the CLI command modes:
• User Top Mode: COMMAND>
• Privileged Top Mode: Switch#
• Global Configuration Mode: Switch(config)#
• Interface Configuration Mode: Switch(interface #)#
