[squid-users] Squid + Cisco 4500 + WCCP2

 I'm trying to setup a transparent proxy with squid using wccpv2 and a
 4507 (ios v15.1) Cisco switch.

 Tried using out of the box rpm package, 3.1.20 on Opensuse 12.1 with no
 luck. My cache.log kept filling with "Unknown capability type in WCCPv2
 Packet" messages.

 Compiled from source the same version with --enable-wccpv2 option but i
 keep getting the same errors.

 Cisco can see the proxy because i get

 show ip wccp web-cache detail --------------------------------

 WCCP Client information:
         WCCP Client ID: X.X.X.62 ---(Proxy address)
         Protocol Version: 2.0
         State: Usable
         Redirection: L2
         Packet Return: L2
         Assignment: MASK
         Connect Time: 17:20:03
         Redirected Packets:
           Process: 0
           CEF: 0
           Platform: 0
         GRE Bypassed Packets:
           Process: 0
           CEF: 0
           Platform: 0
         Mask Allotment: 64 of 64 (100.00%)

 Interesting part is that the messages on the cache.log appear every 10
 sec, same interval that cisco sends the ISY message.

 My SQUID configuration is ---------------------------

 http_port 3127 transparent

 wccp2_router X.X.X.1 ---(switch address)
 wccp2_rebuild_wait on
 wccp2_forwarding_method l2
 wccp2_return_method l2
 wccp2_assignment_method mask
 wccp2_service standard 0

 and Cisco config -----------------------------

 ip wccp web-cache

 interface vlan1 ---(Read that needs to be routed through it to work
 on switches)
 ip wccp web-cache redirect in

 No tunnel defined anywhere cause i assume it's not necessary on l2
 redirection
 Any ideas?

 Thank you in advance
