Document Objectives

This guide contains the commands available for use with the ASA to protect your network from unauthorized use and to establish Virtual Private Networks (VPNs) to connect remote sites and users to your network.

You can also configure and monitor the ASA by using ASDM, a web-based GUI application. ASDM includes configuration wizards to guide you through some common configuration scenarios, and online Help for less common scenarios.

This guide applies to the Cisco ASA series. Throughout this guide, the term "ASA" applies generically to all supported models, unless specified otherwise.

Audience

This guide is for network managers who perform any of the following tasks:

•Manage network security

•Install and configure firewall/security appliances

•Configure VPNs

•Configure intrusion detection software

Use this guide with the CLI configuration guide.

Document Organization

•Using the Command-Line Interface introduces you to the ASA commands and access modes.

•Chapters 1 through 33 list all commands in alphabetical order.

Document Conventions

The ASA command syntax descriptions use the following conventions:

Command descriptions use these conventions:

•Braces ({ }) indicate a required choice.

•Square brackets ([ ]) indicate optional elements.

•Vertical bars ( | ) separate alternative, mutually exclusive elements.

•Boldface indicates commands and keywords that are entered literally as shown.

•Italics indicate arguments for which you supply values.

Examples use these conventions:

•Examples depict screen displays and the command line in screen font.

•Information you need to enter in examples is shown in boldface screen font.

•Variables for which you must supply a value are shown in italic screen font.

•Examples might include output from different platforms; for example, you might not recognize an interface type in an example because it is not available on your platform. Differences should be minor.

No Payload Encryption for Export

You can purchase the ASA 5585-X with No Payload Encryption. For export to some countries, payload encryption cannot be enabled on the Cisco ASA series. The ASA software senses a No Payload Encryption model, and disables the following features and related commands:

•Unified Communications

•VPN

You can still install the Strong Encryption (3DES/AES) license for use with management connections. For example, you can use ASDM HTTPS/SSL, SSHv2, Telnet and SNMPv3. You can also download the dynamic database for the Botnet Traffic Filer (which uses SSL).
