FPM allows customers to create their own filtering policies that can immediately detect and block new viruses and attacks.

A filtering policy is defined via the following tasks:

•Load a PHDF (for protocol header field matching)

•Define a class map and define the protocol stack chain (traffic class)

•Define a service policy (traffic policy)

•Apply the service policy to an interface

The below URL explains about the configuration:
