Configuring DSCP Mapping Using CLI Commands
The following table summarizes the CLI commands for setting the fields in
the
DSCP Mapping
page.
The following is an example of the CLI commands:
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
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).
