Document Objectives

This guide is intended for administrators who want to configure, manage, and monitor standalone Content Engines that are running Cisco Application and Content Networking System (ACNS) 5.5 software.

The term standalone Content Engines is used throughout this guide to refer to Content Engines that the ACNS administrators have intentionally not registered with a Content Distribution Manager so that they can configure, manage, and monitor these Content Engines as standalone devices.

The term locally managed deployments is used throughout this guide to refer to deployments that consist of one or more standalone Content Engines that are running the ACNS 5.x software and are configured as caching and streaming engines.


Note To initially configure a Content Engine as a standalone device, you turn off the autoregistration feature so that the Content Engine will not automatically register with the Content Distribution Manager, and so that you can individually manage it through the Content Engine command-line interface (CLI) or the Content Engine graphical user interface (GUI) as a standalone device.


The Content Engine GUI allows you to configure, manage, and monitor standalone Content Engines remotely through your browser, a console connection or a terminal emulation program. Although either the Content Engine GUI or the CLI can be used to configure and manage standalone Content Engines, the instructions and examples in this guide primarily use the CLI method. (Certain features can be configured through the Content Engine CLI only.) The Content Engine GUI has context-sensitive online help that can be accessed by clicking the HELP button. See Appendix A, "Content Engine GUI Menu Options," for a complete list of Content Engine GUI options.

This guide explains how to configure, manage, and monitor standalone Content Engines running the ACNS 5.4 software for the following purposes:

Transparent forward caching deployments

For conventional caching (DNS, HTTP, HTTPS, and native FTP caching)

For Windows Media Technologies (WMT) transparent caching

For RealMedia transparent caching

Transparent reverse proxy caching deployments (HTTP caching for reverse proxy packets)

Nontransparent forward proxy caching deployments:

For conventional caching (HTTP, HTTPS, and FTP-over-HTTP caching)

For WMT proxy caching

For RealMedia proxy caching

WMT streaming deployments

Real-Time Streaming Protocol (RTSP) streaming deployments


Note If you are using content routing, you must use the Content Distribution Manager. For information about configuring a centrally managed ACNS network device (Content Engines or Content Routers that are registered with a Content Distribution Manager), see the Cisco ACNS Software Configuration Guide for Centrally Managed Deployments, Release 5.5.


Audience

This guide is intended for administrators who want to configure, manage, and monitor standalone Content Engines. The administrator should be familiar with Cisco router and switch configuration. An understanding of caching and streaming concepts is necessary. This guide is not a tutorial.

Document Organization

This guide includes the following chapters and appendixes that are divided into six parts:

Overview that introduces some basic concepts and the typical ways to deploy standalone Content Engines

Basic configuration for standalone Content Engines

Locate the serial number label on your product and record the information before placing a service call.


Submitting a Service Request

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:

http://www.cisco.com/cisco/web/support/index.html

For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

For a complete list of Cisco TAC contacts, go to this URL:

http://www.cisco.com/en/US/support/tsd_contact_technical_support.html

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
