HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 deployment guide (AG421-96001, March 2007)

86 7 - WCCP DEPLOYMENTS
Additional WCCP Features
This section describes the additional features for WCCP.
Security WCCP protocol messages can be authenticated between the router and the HP EFS
WAN Accelerator using a password. The maximum password length is eight
characters.
To set the password
for WCCP
1. On the router, at the system prompt, enter the following command:
Router(config)# ip wccp 90 password <your_password>
2. On the HP EFS WAN Accelerator, at the system prompt, enter the following
command:
client-SH (config) # wccp service-group 90 routers 10.1.0.1 password
<your_password>
NOTE: The same password must be set on the HP EFS WAN Accelerator and the router.
Multicast If you add multiple routers and HP EFS WAN Accelerators to a service group, you can
configure them to exchange WCCP protocol messages through a multicast group.
Configuring a multicast group is advantageous because if a new router is added, it does
not need to be explicitly added on each HP EFS WAN Accelerator.
To configure multicast
groups on your router
• On your 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 group-address 224.0.0.3
Router(config)# interface fastEthernet 0/0
Router(config-if)# ip wccp 90 redirect in
Router(config-if)# ip wccp 90 group-listen
Router(config-if)# end
Router#
TIP: Enter configuration commands, one per line. End each command with CTRL-Z.
