Configuring Special Actions for Application

Inspections (Inspection Policy Map)

Modular Policy Framework lets you configure special actions for many application inspections. When you enable an inspection engine in the service policy, you can also optionally enable actions as defined in an inspection policy map. When the inspection policy map matches traffic within the service policy for which you have defined an inspection action, then that subset of traffic will be acted upon as specified (for example, dropped or rate-limited).

See the “Configuring Application Layer Protocol Inspection” section on page 10-7for a list of applications that support inspection policy maps.

An inspection policy map consists of one or more of the following elements. The exact options available for an inspection policy map depends on the application.

•Traffic matching option—You can define a traffic matching option directly in the inspection policy map to match application traffic to criteria specific to the application, such as a URL string, for which you then enable actions.

–Some traffic matching options can specify regular expressions to match text inside a packet. Be sure to create and test the regular expressions before you configure the policy map, either singly or grouped together in a regular expression class map.

•Inspection class map—An inspection class map includes multiple traffic matching options. You then identify the class map in the policy map and enable actions for the class map as a whole. The difference between creating a class map and defining the traffic match directly in the inspection
