Hi,
Recently I have tried to replace the 7200 series router with the C-3560-E L3 switch but the web-caching seems like not working. I can see both WAEs registered to the switch but no traffic transmit out from the WAE. When I ran the show ip wccp web-cache details and it shows NOT Usable (Incompatible redirection method) so my question is how to make it compatible with the WAE? Is there any WAE documentation I can refer to configure the switch to support L2 redirection?
The following are the L3 Switch configuration:
-----------------------------------------------------------------------------------------------------------------------
ip wccp web-cache
ip wccp 61
ip wccp 62

WAAS does not provide a separate WCCP web-cache service. All WCCP traffic interception in WAAS uses the tcp-promiscuous services (61 & 62). Did you have a separate set of devices running the web-cache service previously?

Hi Zach,
Yes, we are running Web sense in the 10.10.7.0 network. Basically I thought it is as easy as just replace the router with the switch and modify the WAAS to support L2 web cache redirection but it seems like there are more steps to involve.
Please advice what else I need to do in order to enable the web-cache redirection works.
Thanks.

Was the switch running the web-cache service? If so, what was it running the service with? Are the Websense servers running WCCP?

Hi Zach,
Now we are running the C7206 router the web-cache is working fine. The following is the configuration of the router interface:
!
interface FastEthernet0/1
description ** To WAAS Devices **
ip address 10.10.7.1 255.255.255.248
ip pim sparse-mode
ip route-cache flow
duplex auto
speed 100
!
interface FastEthernet2/0
description ** LAN **
ip address 10.10.7.1 255.255.255.0
ip wccp web-cache redirect out
ip wccp 61 redirect in
duplex auto
speed auto
service-policy input REMOTE-LAN-IN
So I guess the only different is the L3 switch only support the L2 web-cache redirection but I can't really find related documentation to configure the WAAS and the L3 switch. Please kindly advice what should be changed in order to make these 2 devices work.
Thanks.

What is the device the 7200 is running the web cache service with? Is is some kind of proxy?

Hi Zach,
I have spent some time to check the design and draw a diagram as per attached. We are using ACNS to cache the web content and I have managed to configure the switch to redirect web-cache traffic by using L2 with Mask assignment but still having some issues:
May you enlighten me for the L2 web cache redirection work for WAN (access through MPLS) as well or only LAN?
Many thanks.
The following are some output from the 3560:
