CLI Reference Guide
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: User EXEC mode, Privileged EXEC mode, Global Configuration mode,
and Interface Configuration mode.
When starting a session, the initial mode is the User EXEC mode. 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
After logging into the device, the user is automatically in User EXEC command mode unless the user is defined as
a privileged user. 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 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.

2. Enter the password and press <Enter>. The password is displayed as *. The Privileged EXEC mode prompt
is displayed. The Privileged EXEC mode prompt consists of the device host name followed by #.
To return from the Privileged EXEC mode to the User EXEC mode, use the disable command. The following
example illustrates how to access the Privileged EXEC mode and return to the User EXEC mode:
The exit command is used to return from any mode to the previous mode except when returning to the User
EXEC mode from the Privileged EXEC mode. For example, the exit command is used to return from the Interface
Configuration mode to the Global Configuration mode.
Global Configuration Mode
Global Configuration mode commands apply to features that affect the system as a whole, rather than just a
specific interface. The configure Privileged EXEC mode command is used to enter the Global Configuration
mode.
To enter the Global Configuration mode perform the following steps:
1. At the Privileged EXEC mode prompt enter the configure command and press <Enter>. The Global
Configuration mode prompt is displayed. The Global Configuration mode prompt consists of the device host
name followed by (config) and #.
To return from the Global Configuration mode to the Privileged EXEC mode, the user can use one of the following
commands:
•exit
•end
•Ctrl+Z
The following example illustrates how to access the Global Configuration mode and return to the Privileged EXEC
mode:

Interface Configuration and Specific Configuration Modes
Interface Configuration mode commands modify specific interface operations. The following are the Interface
Configuration modes:
•Line Interface — Contains commands to configure the management connections. These include commands
such as line timeout settings, etc. The line Global Configuration mode command is used to enter the Line
Configuration command mode.
•VLAN Database — Contains commands to create a VLAN as a whole. The vlan database Global
Configuration mode command is used to enter the VLAN Database Interface Configuration mode.
•Management Access List — Contains commands to define management access-lists. The management
access-list Global Configuration mode command is used to enter the Management Access List Configuration
mode.
•Ethernet — Contains commands to manage port configuration. The interface ethernet Global Configuration
mode command is used to enter the Interface Configuration mode to configure an Ethernet type interface.
•Port Channel — Contains commands to configure port-channels, for example, assigning ports to a port-
channel. Most of these commands are the same as the commands in the Ethernet interface mode, and are
used to manage the member ports as a single entity. The interface port-channel Global Configuration mode
command is used to enter the Port Channel Interface Configuration mode.
•SSH Public Key-chain — Contains commands to manually specify other device SSH public keys. The
crypto key pubkey-chain ssh Global Configuration mode command is used to enter the SSH Public Key-
chain Configuration mode.
•QoS — Contains commands related to service definitions. The qos Global Configuration mode command is
used to enter the QoS services configuration mode.
•MAC Access-List— Configures conditions required to allow traffic based on MAC addresses. The mac
access-list Global Configuration mode command is used to enter the MAC access-list configuration mode.

Using the CLI
Starting the CLI
Page 17
Starting the CLI
The device can be managed over a direct connection to the device console port or via a Telnet connection. The
device is managed by entering command keywords and parameters at the prompt. Using the device Command
Line Interface (CLI) is very similar to entering commands on a UNIX system.
If access is via a Telnet connection, ensure that the device has a defined IP address, corresponding management
access is granted, and the workstation used to access the device is connected to the device prior to using CLI
commands.
Note
The following steps are for use on the console line only.
To start using the CLI, perform the following steps:
1. Connect the DB9 null-modem or cross over cable to the RS-232 serial port of the device to the RS-232 serial
port of the terminal or computer running the terminal emulation application.
Note
The default data rate is 115200.
a) Set the data format to 8 data bits, 1 stop bit, and no parity.
b) Set Flow Control to none.
c) Under Properties, select VT100 for Emulation mode.
d) Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that the setting is for Terminal keys
(not Windows keys).
Note
When using HyperTerminal with Microsoft® Windows 2000,ensure that Windows® 2000 Service Pack 2
or later is installed. With Windows 2000 Service Pack 2, the arrow keys function properly in
HyperTerminal’s VT100 emulation. Go to www.microsoft.com for information on Windows 2000 service
packs.
2. Enter the following commands to begin the configuration procedure:
Console> enable
Console# configure
Console(config)#
3. Configure the device and enter the necessary commands to complete the required tasks.
4. When finished, exit the session with the exit command.
When a different user is required to log onto the system, use the login Privileged EXEC mode command. This
effectively logs off the current user and logs on the new user.

Editing Features
Entering Commands
A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify
configuration parameters. For example, in the command show interfaces status ethernet 1/e11, show,
interfaces and status are keywords, ethernet is an argument that specifies the interface type, and 1/e11
specifies the port.
To enter commands that require parameters, enter the required parameters after the command keyword. For
example, to set a password for the administrator, enter:
Console(config)# username admin password alansmith
When working with the CLI, the command options are not displayed. The command is not selected from a menu,
but is manually entered. To see what commands are available in each mode or within an interface configuration,
the CLI does provide a method of displaying the available commands, the command syntax requirements and in
some instances parameters required to complete the command. The standard command to request help is ?.
There are two instances where help information can be displayed:
•Keyword lookup — The character ?is entered in place of a command. A list of all valid commands and
corresponding help messages are is displayed.
•Partial keyword lookup — If a command is incomplete and or the character ? is entered in place of a
parameter. The matched keyword or parameters for this command are displayed.
To assist in using the CLI, there is an assortment of editing features. The following features are described:
•Terminal Command Buffer
•Command Completion
•Nomenclature
•Keyboard Shortcuts
Terminal Command Buffer
Every time a command is entered in the CLI, it is recorded on an internally managed Command History buffer.
Commands stored in the buffer are maintained on a First In First Out (FIFO) basis. These commands can be
recalled, reviewed, modified, and reissued. This buffer is not preserved across device resets.
By default, the history buffer system is enabled, but it can be disabled at any time. For information about the
command syntax to enable or disable the history buffer, see history.
There is a standard default number of commands that are stored in the buffer. The standard number of 10
commands can be increased to 216. By configuring 0, the effect is the same as disabling the history buffer
system. For information about the command syntax for configuring the command history buffer, see history size.
To display the history buffer, see show history.
Keyword Description
Up-arrow key
Ctrl+P Recalls commands in the history buffer, beginning with the most recent command. Repeats the key sequence to recall successively older commands.
Down-arrow key Returns to more recent commands in the history buffer after recalling
commands with the up-arrow key. Repeating the key sequence will recall
successively more recent commands.
