Abstract
A process of filtering packet data in a network device is disclosed. A descriptor table is accessed to obtain a first descriptor and a first field is extracted from a packet based on the first descriptor. An action table is accessed based on a value of the first field of the packet. Then an action from the action table is executed when a valid bit from the action table for the action is set or an action from a miss action table is executed when a valid bit from the action table for the action is not set.
