HP STORAGEWORKS ENTERPRISE FILE SERVICES WAN ACCELERATOR DEPLOYMENT GUIDE 77
7 - WCCP DEPLOYMENTS
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.
IMPORTANT: HP recommends that you redirect packets coming into the LAN interface of the
router with the redirect in feature on the router instead of the redirect out feature on the WAN
interface of the router so that packets do not go through the routing code twice on the router.
Only use the redirect out feature if it is impossible to use the redirect in feature.
To configure the
WCCP router
• At the system prompt, enter the following set of commands:
Router> enable
Router# configure terminal
Router(config)# ip wccp version 2
Router(config)# ip wccp 90
Router(config)# interface fastEthernet 0/0
Router(config-if)# ip wccp 90 redirect in
Router(config-if)# end
Router#
TIP: Enter configuration commands, one per line. End with CRTL-Z.
The service group 90 must be defined and configured on the HP EFS WAN
Accelerator.
IMPORTANT: If you add the same WCCP service group to more than one HP EFS WAN
Accelerator, you should add the default HP EFS WAN Accelerator in-path port, 7800, to the
router deny list. Configure a router deny list with the router command access-list <redirect list
number> deny ip <host> <destination>.
Configuring the
Client-Side HP
EFS WAN
Accelerator
You configure the client-side HP EFS WAN Accelerator to be an in-path device with
WCCP support, and you add the service group (that you defined on the router) to it.
