Chapter 47 Configuring Web Cache Services By Using WCCP
Configuring WCCP
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip wccp {web-cache | service-number}
[group-address groupaddress]
[group-list access-list] [redirect-list
access-list] [password
encryption-number password]
Enable the web cache service, and spec
ify the service number which
corresponds to a dynamic service that is defined by the application
engine. By default, this feature is disabled.
(Optional) For gr
oup-address groupaddress, specify the multicast group
address used by the switches and the application engines to participate in
the service group.
(Optional) For gr
oup-list access-list, if a multicast group address is not
used, specify a list of valid IP addresses that correspond to the application
engines that are participating in the service group.
(Optional) For r
edirect-list access-list, specify the redirect service for
specific hosts or specific packets from hosts.
(Optional) For passw
ord encryption-number password, specify an
encryption number. The range is 0 to 7. Use 0 for not encrypted, and use
7 for proprietary. Specify a password name up to seven characters in
length. The switch combines the password with the MD5 authentication
value to create security for the connection between the switch and the
application engine. By default, no password is configured, and no
authentication is performed.
You must configure the same passw
ord on each application engine.
When authentication is enable
d, the switch discards messages that are not
authenticated.
Step 3
interface interface-id Specify the interface connected to the application engine or the web
server, and enter interface configuration mode.
Step 4
no switchport Enter Layer 3 mode.
Step 5
ip address ip-address subnet-mask Configure the IP address and subnet mask.
Step 6
no shutdown Enable the interface.
Step 7
exit Return to global configuration mode. Repeat Steps 3 through 7 for each
application engine and web server.
Step 8
interface interface-id Specify the interface connected to the client, and enter interface
configuration mode.
Step 9
no switchport Enter Layer 3 mode.
Step 10
ip address ip-address subnet-mask Configure the IP address and subnet mask.
Step 11
no shutdown Enable the interface.
Step 12
ip wccp {web-cache | service-number}
redirect in
Redirect packets received from the client to the application engine.
Enable this on the interface connected to the client.
Step 13
ip wccp {web-cache | service-number}
group-listen
(Optional) When using a multicast group address, group-listen enables
the interface to listen for the multicast address. Enable this on the
interface connected to the application engine.
Step 14
exit Return to global configuration mode. Repeat Steps 8 through 13 for each
client.
Step 15
end Return to privileged EXEC mode.
