A MAC-based ACL, IP-based ACL, and an IPv6-based ACL can be combined into a class map. Class maps are configured to match packet criteria on a match-all or match-any basis. They are matched to packets on a first-fit basis, meaning that the action associated with the first-matched class map is the action performed by the system. Packets that match the same class map belong to the same flow. There are two possible types of matching: • match-all - Traffic matches class map if it matches IP/IPV6 and MAC ACLs • match-any - Traffic matches class map if it matches at least one of the ACLs If a more complex set of rules is needed, several class maps can be grouped into a super-group called a policy (see "Defining Class Mapping Using CLI Commands" on page 674). 672 Dell PowerConnect 55xx Systems User Guide
