Preface
Audience
This guide is for the networking professional managing the Cisco Metro Ethernet (ME) 3600X-24CX
switch, hereafter referred to as the switch. We assume that you are familiar with the concepts and
terminology of Ethernet and local area networking. If you are interested in more training and education
in these areas, learning opportunities including training courses, self-study options, seminars, and career
certifications programs are available on the Cisco Training & Events web page:
http://www.cisco.com/web/learning/index.html
Purpose
This guide provides an overview of software functionality that is specific to the Cisco ME 3600X
24CX Series Switch. It is not intended as a comprehensive guide to all of the software features that can
be run using the Cisco ME 3600X 24CX Series Switch, but only the software aspects that are specific to
this platform.
For information on general software features that are also available on other Cisco platforms, see the
Cisco IOS technology guide for that specific software feature.
For the latest documentation updates, see the release notes for this release.

Using the Command-Line Interface
This chapter describes the Cisco IOS command-line interface (CLI) and how to use it to configure your
Cisco ME 3600X-24CX switch. It contains these sections:
• Understanding Command Modes, page 1-1
• Understanding the Help System, page 1-3
• Understanding Abbreviated Commands, page 1-3
• Understanding no and default Forms of Commands, page 1-4
• Understanding CLI Error Messages, page 1-4
• Using Command History, page 1-4
• Using Editing Features, page 1-6
• Searching and Filtering Output of show and more Commands, page 1-8
• Accessing the CLI, page 1-9
Understanding 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.
When you start a session on the switch, 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.
Table 1-1 describes the main command modes, how to access each one, the prompt you see in that mode,
and how to exit the mode. The examples in the table use the hostname Switch.
