66 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. The server-side is assumed to be out-of-path.
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.)
The service group ID is 90 and the interface with packets coming from the
LAN is fastEthernet0/0.
