How are Mac ACLS similar to IP ACLs?

MAC ACLs are ACLs that filter traffic using information in the Layer 2 header of each packet. MAC ACLs share many fundamental concepts with IP ACLs, including support for virtualization. For information about these shared concepts, see the “Information About ACLs” section on page 11-1.
