WCCP redirect on 4507 to ironport

I am trying to setup WCCP on our 4507. For some reason I cannot get this to work! The config I have tried is below. I can't figure out what I'm doing wrong here!

ip wccp web-cache group-list IRONPORT-GROUPLIST

ip wccp source-interface GigabitEthernet2/24

!

Interface Vlan160

ip address 10.10.16.1 255.255.254.0

ip wccp web-cache redirect out

!

ip access-list IRONPORT-GROUPLIST

permit ip any host 10.11.1.10 (10.11.1.10 is the ironport proxy IP address)

On the ironport I setup web-cache under transparent redirection and provided the IP address I used to source from above (GigabitEthernet2/24). Here is the output I get on the 4507:

10CSW-LAN1#sh ip wccp web-cache

Here is the debug output:

I would recommend doing the following. Also feel free to call into the ironport support line. It is listed at the bottom of the page.

  • Change the wccp service to service-number 90
  • Try to redirect inbound traffic not outbound traffic.
  • Set Load-balancing to mask
  • Set forward method to L2
  • Set return method to L2

ip wccp 90 group-list IRONPORT-GROUPLIST  <- Set the wccp service-number

ip wccp source-interface GigabitEthernet2/24

!

Interface Vlan160

ip address 10.10.16.1 255.255.254.0

ip wccp 90 redirect out  <- Set the WCCP Service-number try to redirect inbound traffic

!

ip access-list IRONPORT-GROUPLIST

permit ip any host 10.11.1.10 (10.11.1.10 is the ironport proxy IP address)

Below is an example of how you should setup your ironport for a customer service number. Place the port numbers that you want to redirect.

hi

I have the same setup, and it works.

--> sh ip wccp web-cache detail

are you using GRE or L2?
