Class Mapping

A Class Map defines a traffic flow associated with ACL(s). 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

match-any — Traffic matches class map if it matches at least one of the

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 685).
