Defining Class Mapping
The 
Class Mapping Page
 contains parameters for defining class maps. One IP ACL 
and/or one MAC ACL comprise a class map. Class maps are configured to match 
packet criteria, and are matched to packets on a first-fit basis. For example, Class 
Map A is assigned to packets based only on an IP-based ACL or a MAC-based 
ACL. Class Map B is assigned to packets based on both an IP-based and a MAC-
based ACL.
