CHAPTER

Overview of the ACS Command Line Interface
Cisco Secure Access Control System (ACS) 5.1 uses the CSACS-1121 appliance running the Cisco
Application Deployment Engine (ADE) OS 1.2. This chapter provides an overview of how to access the
ACS command-line interface (CLI), the different command modes, and the commands that are available
in each mode.
You can configure and monitor ACS 5.1 through the web interface. You can also use the CLI to perform
the configuration and monitoring tasks that this guide describes.
The following sections describe the ACS CLI:
• Accessing the ACS Command Environment, page 1-1
• User Accounts and Modes in ACS, page 1-1
• Types of Command Modes in ACS, page 1-5
• CLI Audit, page 1-11
Accessing the ACS Command Environment
You can access the ACS CLI through a secure shell (SSH) client or the console port using one of the
following machines:
• Windows PC running Windows XP/Vista.
• Apple Computer running Mac OS X 10.4 or later.
• PC running Linux.
For detailed information on accessing the CLI, see Chapter 2, “Using the ACS Command Line
Interface.”
User Accounts and Modes in ACS
Two different types of accounts are available on the ACS server:
• Admin (administrator)
• Operator (user)

1-2
CLI Reference Guide for the Cisco Secure Access Control System 5.1
OL-18996-01
Chapter 1 Overview of the ACS Command Line Interface
User Accounts and Modes in ACS
When you power up the CSACS-1121 appliance for the first time, you are prompted to run the setup
utility to configure the appliance. During this setup process, an administrator user account, also known
as an Admin account, is created. After you enter the initial configuration information, the appliance
automatically reboots and prompts you to enter the username and the password that you specified for the
Admin account. It is this Admin account that you must use to log in to the ACS CLI for the first time.
While an Admin can create and manage Operator (user) accounts (which have limited privileges and
access to the ACS server), an Admin account provides you the functionality you require to use the ACS
CLI.
To create more users (with admin and operator privileges) with SSH access to the ACS CLI, you must
run the username command in the Configuration mode (see Types of Command Modes in ACS,
page 1-5).
Table 1-1 lists the command privileges for each type of user account: Admin and Operator (user).

Chapter 1 Overview of the ACS Command Line Interface
Types of Command Modes in ACS
You can always tell when you are in the Operator (user) mode or Admin (EXEC) mode by looking at the
prompt. A right angle bracket (>) appears at the end of the Operator (user) mode prompt; a pound sign
(#) appears at the end of the Admin mode prompt, regardless of the submode.
The ACS configuration mode requires a specific, authorized user role to execute each ACS configuration
command; see ACS Configuration Commands, page 1-8.
Types of Command Modes in ACS
ACS supports these command modes:
• EXEC—Use the commands in this mode to perform system-level configuration. In addition, certain
EXEC mode commands have ACS-specific abilities. See EXEC Commands, page 1-5.
• ACS configuration—Use the commands in this mode to import or export configuration data,
synchronize configuration information between the primary and secondary ACS, reset IP address
filtering and management interface certificate, define debug logging and show the logging status.
This mode requires an administrator user account to log in and perform the ACS
configuration-related commands. See ACS Configuration Commands, page 1-8.
• Configuration—Use the commands in this mode to perform additional configuration tasks in ACS.
See Configuration Commands, page 1-10.
EXEC Commands
EXEC commands primarily include system-level commands such as show and reload (for example,
application installation, application start and stop, copy files and installations, restore backups, and
display information). In addition, certain EXEC-mode commands have ACS-specific abilities (for
example, start an ACS instance, display and export ACS logs, and reset an ACS configuration to factory
default settings.
• Table 1-2 lists the EXEC commands and provides a short description of each.
• Table 1-3 lists the show commands in the EXEC mode and provides a short description of each.
For detailed information on EXEC commands, see Understanding Command Modes, page 2-6.
EXEC or System-Level Commands
Table 1-2 describes the EXEC mode commands.
