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
).
To define a class map:
1
Click Quality of Service > QoS Advanced Mode > Class Mapping to
display the
Class Mapping: Summary page.
The previously-defined class maps are displayed.
2 To add a class map, click Add .
A new class map is added by selecting one or two ACLs and assigning them
a class map name. If a class map has two ACLs, specify that a frame must
match both ACLs, or that it must match either one or both of the ACLs
selected.
3 Enter the parameters.
