Chapter 43 Configuring Web Cache Services By Using WCCP
Configuring WCCP
Beginning in privileged EXEC mode, follow these steps to enable the web cache service, to set a
multicast group address or group list, to configure routed interfaces, to redirect inbound packets received
from a client to the application engine, enable an interface to listen for a multicast address, and to set a
password. This procedure is required.
Note
Before configuring WCCP commands, configure the SDM template, and reboot the switch. For more
information, see
Chapter 8, “Configuring SDM Templates.”

[

[

]
Enable the web cache service, and specify the service number which
corresponds to a dynamic service that is defined by the application
engine. By default, this feature is disabled.
(Optional) For
group-address
groupaddress
, specify the multicast group
address used by the switches and the application engines to participate in
the service group.
(Optional) For
group-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
redirect-list
access-list
, specify the redirect service for
specific hosts or specific packets from hosts.
(Optional) For
password
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 password on each application engine.
When authentication is enabled, 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.
