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, 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.

Understanding Abbreviated Commands
You need to enter only enough characters for the switch to recognize the command as unique.
This example shows how to enter the show configuration privileged EXEC command in an abbreviated form:
Switch# show conf
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 switch.

Configuration Logging
You can log and view changes to the switch 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
notification to registered applications whenever the configuration changes. You can choose to have the
notifications sent to the syslog.
Only CLI or HTTP changes are logged.Note
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.

Configuration Logging

Changing the Command History Buffer Size
By default, the switch 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 switch records during
the current terminal session in the privileged EXEC mode. You can
configure the size from 0 through 256.
terminal history [size number-of-lines]
Example:
Switch# terminal history size 200
Step 1
Recalling Commands
To recall commands from the history buffer, perform one of the actions listed in this table. These actions are
optional.
The arrow keys function only on ANSI-compatible terminals such as VT100s.Note
SUMMARY STEPS
1. Ctrl-P or use the up arrow key
2. Ctrl-N or use the down arrow key
3. show history
DETAILED STEPS
PurposeCommand or Action

Repeat the key sequence to recall successively older commands.
Ctrl-P or use the up arrow key
Step 1
Returns to more recent commands in the history buffer after recalling commands
with Ctrl-P or the up arrow key. Repeat the key sequence to recall successively
more recent commands.

Ctrl-V or Esc Q
Scrolls down a line or screen on displays that are
longer than the terminal screen can display.

prompt.
Note

Redisplays the current command line if the switch
suddenly sends a message to your screen.
Ctrl-L or Ctrl-R
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 extend beyond a single line on the screen.

wide. If you have a different width, use the terminal width privileged
EXEC command to set the width of your terminal.
Use line wrapping with the command history feature to recall and
modify previous complex command entries.
Searching and Filtering Output of show and more Commands
You can search and filter the output for show and more commands. This is useful when you need to sort
through large amounts of output or if you want to exclude output that you do not need to see. Using these
commands is optional.

Accessing the CLI through a Console Connection or through Telnet
Before you can access the CLI, you must connect a terminal or a PC to the switch console or connect a PC to
the Ethernet management port and then power on the switch, as described in the hardware installation guide
that shipped with your switch.
If your switch is already configured, you can access the CLI through a local console connection or through a
remote Telnet session, but your switch must first be configured for this type of access.
You can use one of these methods to establish a connection with the switch:
•Connect the switch console port to a management station or dial-up modem, or connect the Ethernet
management port to a PC. For information about connecting to the console or Ethernet management
port, see the switch hardware installation guide.
•Use any Telnet TCP/IP or encrypted Secure Shell (SSH) package from a remote management station.
The switch must have network connectivity with the Telnet or SSH client, and the switch must have an
enable secret password configured.
•The switch supports up to 16 simultaneous Telnet sessions. Changes made by one Telnet user are
reflected in all other Telnet sessions.
•The switch supports up to five simultaneous secure SSH sessions.
After you connect through the console port, through the Ethernet management port, through a Telnet
session or through an SSH session, the user EXEC prompt appears on the management station.
