"Traffic Hijacking Options

In the integrated configuration, there is only one traffic hijacking 
option-sending an RHI message from the Anomaly Guard to the routing process 
of the supervisor engine to add a static route to the supervisor engine 
routing table that names the Anomaly Guard as the next hop.

In the dedicated configuration, there is only one option for the first step 
of the process-sending an RHI message from the Anomaly Guard Module to the 
supervisor engine on the same Cisco Catalyst 6500 Series switch chassis."

Can anyone point me at a Networkers or other resource that explains RHI 
and/or other internal 6500 service modules in how they "slot" in and "see" 
traffic in a transparent fashion?

There is a bit of info on RHI located at:
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/csm/3.1/configuration/guide/helthmon.html#wp1025239
but not much.

Thanks,
Hank
