Hi all,
I have an IronPort S160 which has been working fine as an explicit proxy for a while, but I want to start using WCCPv2 instead (via a Cisco 1801 router).
I have followed so many guides and manuals but I jus can't get it to work. When all is activated, my clients just time-out when they attempt to access the internet.
I would be very grateful if anyone could lend some assistance.
On the IronPort I have:
+----------+
| IRONPORT |

| +-----| SWITCHES | +--------+
+-----P2: 10.11.2.249-------+ | |--10.11.2.250--| WWW GW |

| |
| |
+---------------[vlan22]10.11.22.254-------+
My Cisco 1801 router config is as follows:

I think that on the Iron Port that you only need to specify one address for the router. But I do not know that having multiple addresses for the same router would cause problems.
Your drawing show the router and core switches but does not tell us much about their relationship. Are the core switches just layer 2 or are they layer2/layer 3? And in particular - is all inter vlan routing done on the router or is it possible that some routing is done on the core switches?
What output do you get for show ip wccp on the router?

Hi Rick,
Thank you very much for your reply.
I will try to answer your questions as best I can.
1) The switches are just layer 2, as far as I am aware.
2) Inter vlan routing is only done on the router.
I have since changed the interface facing the internet from a vlan (vlan2) to a layer 3 port (fe0), just incase WCCP had some inssue with operating on a vlan port.
My new config looks as follows:
+----------+
| IRONPORT |
+----------+
| | |
| | +-M1: 10.11.23.250------+ +----------+
| | +-----| |
| +---P1: 10.11.1.250-------------| CORE |
| +-----| SWITCHES | +--------+
+-----P2: 10.11.2.249-------+ | |--10.11.2.250--| WWW GW |
| | +--------+
+----------+
| | | |
+-------------[fe0]10.11.1.254-----+ | | |

| | | |
| +---------[vlan23]10.11.23.254-----+ |
| |
| |
+---------------[vlan22]10.11.22.254-------+
When WCCPv2 is acivated on the IronPort and router, I see the following results on the router:
rtr-hq1-2#show ip wccp
Global WCCP information:

The "Total Packets s/w Redirected" seem to increase quite quickly, which I would guess suggests that the router is forwarding the requests out, but it's as though they're not reaching the IronPort.
Any further assistance is extremely well received.
