CHAPTER 7 WCCP Deployments

CHAPTER 7 WCCP Deployments

In This Chapter	This chapter describes how to configure the Web Cache Communication Protocol
	(WCCP) to redirect traffic to an HP EFS WAN Accelerator or group of HP EFS WAN
	Accelerators. It contains the following sections:
	“Introduction to WCCP,” next
	“Connecting the HP EFS WAN Accelerator to Your Network in WCCP
	Deployments” on page 67
	“A Basic WCCP Configuration” on page 68
	“Configuring WCCP Using the Management Console” on page 70
	“Dual WCCP Deployment” on page 76
	“Additional WCCP Features” on page 79
	“Troubleshooting” on page 82
	This chapter assumes you are familiar with the HP EFS WAN Accelerator
	Management Console (Management Console). For detailed information about the
	Management Console and how to use it, see the HP Enterprise File Services WAN
	Accelerator Management Console User Guide.
	This chapter also assumes that you are familiar with the installation and configuration
	process for the HP EFS WAN Accelerator. For detailed information, see the HP
	StorageWorks Enterprise File Services WAN Accelerator Installation and
	Configuration Guide.
	This chapter provides the basic steps for WCCP network deployments. It does not
	provide detailed procedures. Use this chapter as a general guide to these deployments.
	If you need additional assistance, contact HP technical support located at http://
	www.hp.com.
	For detailed information about the factors you must consider before you design and
	deploy the HP EFS WAN Accelerator in a network environment, see “Design and
	Deployment Overview” on page 11.
