About This Guide

This guide provides instructions for configuring the advanced features of the

Cisco 11500 and 11000 series content services switch (hereinafter referred to as

the CSS). Information in this guide applies to all CSS models except where noted.

For information on CSS administration, refer to the Cisco Content Services Switch

Administration Guide. For information on basic CSS configuration, refer to the

Cisco Content Services Switch Basic Configuration Guide.

The CSS software is available in a Standard or Enhanced feature set. The

Enhanced feature set contains all of the Standard feature set and also includes

Network Address Translation (NAT) Peering, Domain Name Service (DNS),

Demand-Based Content Replication (Dynamic Hot Content Overflow), Content

Staging and Replication, and Network Proximity DNS. Proximity Database and

SSH are optional features.

Note You must enter a software license key when you boot the CSS for the first time.

After you boot the CSS, you can activate a CSS software option (for example,

SSH) that you purchased using the license command. For more information, refer

to the Cisco Content Services Switch Hardware Installation Guide, Chapter 3,

Booting and Configuring the CSS.

Note If you configure your 11000 series CSS for Proximity Database, you cannot use

the CSS for load balancing. For details on Proximity Database, refer to Chapter 5,

Configuring Network Proximity.

Technical Assistance Center

The Cisco Technical Assistance Center (TAC) is available to all customers who

need technical assistance with a Cisco product, technology, or solution. Two

levels of support are available: the Cisco TAC Web Site and the Cisco TAC

Escalation Center.

Cisco TAC inquiries are categorized according to the urgency of the issue:

•Priority level 4 (P4)—You need information or assistance concerning Cisco

product capabilities, product installation, or basic product configuration.

•Priority level 3 (P3)—Your network performance is degraded. Network

functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded,

affecting significant aspects of business operations. No workaround is

available.

•Priority level 1 (P1)—Your production network is down, and a critical impact

to business operations will occur if service is not restored quickly. No

workaround is available.

The Cisco TAC resource that you choose is based on the priority of the problem

and the conditions of service contracts, when applicable.

Cisco TAC Web Site

You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving

both cost and time. The site provides around-the-clock access to online tools,

knowledge bases, and software. To access the Cisco TAC Web Site, go to this

URL:

http://www.cisco.com/tac

About This Guide

Obtaining Technical Assistance

Cisco Content Services Switch Advanced Configuration Guide 78-13887-03

All customers, partners, and resellers who have a valid Cisco service contract have

complete access to the technical support resources on the Cisco TAC Web Site.

The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have

a valid service contract but do not have a login ID or password, go to this URL to

http://www.cisco.com/register/

If you are a Cisco.com registered user, and you cannot resolve your technical

issues by using the Cisco TAC Web Site, you can open a case online by using the

TAC Case Open tool at this URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, we recommend that you open P3 and P4 cases through

the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2

issues. These classifications are assigned when severe network degradation

significantly impacts business operations. When you contact the TAC Escalation

Center with a P1 or P2 problem, a Cisco TAC engineer automatically opens a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country,

go to this URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operationscenter to determine the

level of Cisco support services to which your company is entitled: for example,

SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When

you call the center, please have available your service agreement number and your

product serial number.
