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

80 7 - WCCP DEPLOYMENTS
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.
To configure multicast
groups on the HP EFS
WAN Accelerator
• On the client-side HP EFS WAN Accelerator, at the system prompt, enter the
following set of commands:
client-SH > enable
client-SH # configure terminal
client-SH (config) # wccp enable
client-SH (config) # wccp mcast-ttl 10
client-SH (config) # wccp service-group 90 routers 224.0.0.3
client-SH (config) # write memory
client-SH (config) # exit
TCP Port
Redirection
By default, all TCP ports are redirected, but the HP EFS WAN Accelerator can be
configured to tell the router to redirect only certain TCP source or destination ports. A
maximum of 7 ports can be specified per service groups.
NOTE: You do not need to configure source and destination ports on the router.
To configure TCP port
redirection
• On the client-side HP EFS WAN Accelerator, at the system prompt, enter the
following command:
