A Basic WCCP Configuration

This section describes how to configure a router and the HP EFS WAN Accelerator to use WCCP to redirect traffic in a single subnet using the CLI.

You can also use the Management Console to configure the HP EFS WAN Accelerator to use WCCP. In this example the server-side is assumed to be out-of-path.

IMPORTANT: This is an example of one type of WCCP deployment. You can also have deployments with both HP EFS WAN Accelerators configured as in-path devices and WCCP configured on one of them.

Figure 7-2.Basic WCCP Configuration

To set up an HP EFS WAN Accelerator for WCCP, the HP EFS WAN Accelerator WAN interface is connected to a switch or router (not necessarily the one configured for WCCP) that can reach the switch or router where WCCP is configured and where redirection will occur.

IMPORTANT: When you connect to the WAN port on the HP EFS WAN Accelerator for WCCP, the LAN port no longer passes traffic. You cannot run the HP EFS WAN Accelerator in both in-path and client, out-of-path mode.

Configuring the WCCP Router or Multi-Layer Switch

Before you configure the HP EFS WAN Accelerator, you enable your router for WCCP. You create a service group and attach it to the interface where you want packets to be redirected.

In this example, you configure unicast protocol messages between the router and the HP EFS WAN Accelerator and all traffic is redirected to the HP EFS WAN Accelerator. (The HP EFS WAN Accelerator tells the router to redirect TCP traffic and, if configured on it, certain TCP ports.)
