HP StorageWorks Enterprise File Services WAN Accelerator 2.1.5 deployment guide (June 2006)

68 7 - WCCP DEPLOYMENTS
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
Connecting the
HP EFS WAN
Accelerator
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.)
