CHAPTER 1
Using the Command-Line Interface
•Information About Using the Command-Line Interface, page 1
•How to Use the CLI to Configure Features, page 6
Information About Using the Command-Line Interface
Command Modes
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, an 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 controller 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 controller 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.

OL-32314-01 3
Using the Command-Line Interface
Understanding Abbreviated Commands

No and Default Forms of Commands
Almost every configuration command also has a no form. In general, use the no form to disable a feature or
function or reverse the action of a command. For example, the no shutdown interface configuration command
reverses the shutdown of an interface. Use the command without the keyword no to reenable a disabled feature
or to enable a feature that is disabled by default.
Configuration commands can also have a default form. The default form of a command returns the command
setting to its default. Most commands are disabled by default, so the default form is the same as the no form.
However, some commands are enabled by default and have variables set to certain default values. In these
cases, the default command enables the command and sets variables to their default values.
CLI Error Messages
This table lists some error messages that you might encounter while using the CLI to configure your controller.

How to Get HelpMeaningError Message

a question mark (?) without any
space between the command and

Configuration Logging
You can log and view changes to the controller configuration. You can use the Configuration Change Logging
and Notification feature to track changes on a per-session and per-user basis. The logger tracks each
configuration command that is applied, the user who entered the command, the time that the command was
entered, and the parser return code for the command. This feature includes a mechanism for asynchronous

How to Use the CLI to Configure Features
Configuring the Command History
The software provides a history or record of commands that you have entered. The command history feature
is particularly useful for recalling long or complex commands or entries, including access lists. You can
customize this feature to suit your needs.
Changing the Command History Buffer Size
By default, the controller records ten command lines in its history buffer. You can alter this number for a
current terminal session or for all sessions on a particular line. This procedure is optional.
SUMMARY STEPS
1. terminal history [size number-of-lines]
DETAILED STEPS
PurposeCommand or Action
Changes the number of command lines that the controller records
during the current terminal session in privileged EXEC mode. You
can configure the size from 0 to 256.

Editing Command Lines That Wrap
You can use a wraparound feature for commands that extend beyond a single line on the screen. When the
cursor reaches the right margin, the command line shifts ten spaces to the left. You cannot see the first ten
characters of the line, but you can scroll back and check the syntax at the beginning of the command. The
keystroke actions are optional.
To scroll back to the beginning of the command entry, press Ctrl-B or the left arrow key repeatedly. You can
also press Ctrl-A to immediately move to the beginning of the line.
The arrow keys function only on ANSI-compatible terminals such as VT100s.Note
The following example shows how to wrap a command line that extends beyond a single line on the screen.
