Cisco Systems 3560 Manual De Usuario

You cannot configure WCCP and a private VLAN (PVLAN) on the same switch interface.

For WCCP packet redirection to operate, you must configure the switch interface connected to the client 
to redirect inbound packets.

This procedure shows how to configure these features on routed ports. To configure these features on 
SVIs, see the configuration examples that follow the procedure.

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.

Before configuring WCCP commands, configure the SDM template, and reboot the switch. For more 
information, see 

Enter global configuration mode.

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 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.

interface interface-id

Specify the interface connected to the application engine or the web 
server, and enter interface configuration mode.

Enter Layer 3 mode.

ip address ip-address subnet-mask

Configure the IP address and subnet mask.
