ACL Mechanisms
For many applications of ACLs, it is not necessary to know the details of
how ACLs work. However, if you find that your application of ACLs is constrained by hardware
limitations, you can often rearrange the ACLs to use the hardware more efficiently. The
following sections go into some detail about how the ACLs use hardware resources, and provide
some suggestions about how to reorder or rewrite ACLs to use fewer resources.
