A controllable mechanism for by-passing Layer (L ) classification is based on the insertion into a set of MAC rules in SA MAC lookup means a set of Layer (L ) Skip Classification Flags. Routing is accomplished by selecting which rule to apply to the packet and reading the state of the corresponding L Skip Classification Flag. In response to a first state of said corresponding L Skip Classification Flag, performing an L classification followed by a routing of the data packet. In response to a second state of said corresponding L Skip Classification Flag, reading the state of a Global Classification Flag. In response to a first state of said Global Classification Flag, performing an L classification followed by a routing of said data packet. In response to a second state of said Global Classification Flag performing a routing of the data packet. The L Skip option change does not use the option change of reading the L Skip Classification Flag from the port table, whereas the second embodiment uses this option. The third and fourth embodiments are similar to the first and second embodiments but with the. addition of inserting into a set of Layer (L ) rules in L lookup means a set of Layer (L ) Classification Required Flags.
