4.9.7 LAN and In-Path Interface Requirements for WCCP
The FX Series uses the eth2 physical interface to conduct the WCCP protocol with the router or
switch and also to receive redirected requests and responses. Therefore in order to configure
WCCP, you must define an in-path interface with an IP address that is on the same subnet as the
Cisco router or switch. The gateway for this in-path interface must be that of the Cisco router or
switch
interface the appliance is connected to . The VLAN ID must be 0. Following this, a LAN
interface must be defined for eth3 and assigned to the aforementioned In-Path interface.
4.9.8 Configuring WCCP on earlier models
On FX-1000 and some earlier models of FX-4000, the specialized fail-to-wire network interface
card requires that an eth3 LAN interface be defined in order to run WCCP over eth2, even though
it’s not actually used. Therefore, on an FX-1000, an in-path interface with a non-existent VLAN
must be defined. This in-path interface must subsequently be assigned to a LAN interface for
eth3. It is not required that the eth3 physical interface be cabled to anything.
