Parameterized Filters Overview

Parameterized filters are configured under a dynamic profile. The filter definition can utilize dynamic-profile variables, allowing their configuration to be customized at session creation time. The user can configure a general baseline filter under a dynamic profile and then provide specific variables of that filter when a dynamic session is activated. These variables can include policing rates, destination addresses, ports, and other items.

In order to provide better scaling, the system analyzes a dynamic profile, and then determines whether the set of variables for one session is the same as for a previous session. Each set of variables is assigned a unique identifier (UID). If a matching filter already exists, the session creates an interface-specific filter copy of that filter template. If the filter does not already exist, the session reads the configuration and compiles a new filter. This filter is installed as a template with an interface-specific filter copy for the current session pointing at it.
