Using the Command-Line Interface

•

The Cisco IOS user interface is divided into many different modes. The commands available to you depend

on which mode you are currently in. Enter a question mark (?) at the system prompt to obtain a list of commands

available for each command mode.

You can start a CLI session through a console connection, through Telnet, a SSH, or by using the browser.

When you start a session, you begin in user mode, often called user EXEC mode. Only a limited subset of

the commands are available in user EXEC mode. For example, most of the user EXEC commands are one-time

commands, such as show commands, which show the current configuration status, and clear commands,

which clear counters or interfaces. The user EXEC commands are not saved when the switch reboots.

To have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a password

to enter privileged EXEC mode. From this mode, you can enter any privileged EXEC command or enter

global configuration mode.

Using the configuration modes (global, interface, and line), you can make changes to the running configuration.

If you save the configuration, these commands are stored and used when the switch reboots. To access the

various configuration modes, you must start at global configuration mode. From global configuration mode,

you can enter interface configuration mode and line configuration mode.

This table describes the main command modes, how to access each one, the prompt you see in that mode, and

how to exit the mode.
