You can set virtual in-path settings in the General Service Settings (SteelHead Interceptor) page when the Interceptor is running in standard mode.
Important: WCCP is not supported when the Interceptor is running in VLAN segregation mode.
For details, see the SteelHead Interceptor User’s Guide or the SteelHead Interceptor Deployment Guide.

Description
Enable PBR/WCCP
Enables the virtual in-path support on all the interfaces for networks that use PBR or WCCP.
•  Policy-based routing (PBR) - PBR allows you to define policies to route packets instead of relying on routing protocols. You enable PBR to redirect traffic that you want optimized by an Interceptor that is not in the direct physical path between the client and server.
•  Web Cache Communication Protocol (WCCP) - If your network design requires you to use WCCP, a packet redirection mechanism, it directs packets to RiOS appliances that are not in the direct physical path to ensure that they are optimized.
External traffic redirection is supported on only the first in-path interface.
Enable CDP for PBR
For a failover deployment that uses PBR rather than WCCP to redirect traffic to a backup appliance select Enable CDP for PBR.
•  CDP Hold Time - Specify the CDP message hold time, in seconds. The default value is 180 seconds.
•  CDP Interval - Specify the CDP message polling interval, in seconds. The default value is 10 seconds.
