Abstract
A network device and a method of handling a frame in a network device defining a common header for each rule in a rules table of a search engine, wherein the common header comprises a source port specifying a corresponding rule to be applied to a port or ports, and a frame format specifying a format applied to the corresponding rule. A port receives a frame, with the frame having multiple field values. A pre-parser parses the received frame to obtain the field values and corresponding slices. A search engine receives the slices and determines matches between the slices and the common header of each rule in the rules table. A policy table performs indexing based on the determined matches to obtain an action entry. An action resolution takes an action based on the obtained action entry.
