HP EFS WAN ACCELERATOR DEPLOYMENT GUIDE 77
7 - WCCP DEPLOYMENTS
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 stem 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.
