Defining Class Mapping
A Class Map defines a traffic flow with ACLs (Access Control Lists). A MAC ACL,
IP ACL, and IPv6 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
matches the same class map are considered to belong to the same flow.
NOTE Defining class maps does not have any effect on QoS; it is an interim step, enabling
the class maps to be used later.
If more complex sets of rules are needed, several class maps can be grouped into
a super-group called a policy (see the Configuring a Policy section).
The Class Mapping Page shows the list of defined class maps and the ACLs
comprising each, and enables you to add/delete class maps.
To define a class map:
STEP 1 Click Quality of Service > QoS Advanced Mode > Class Mapping. The Class
Mapping Page opens.
This page displays the already-defined class maps.
STEP 2 Click Add. The Add Class Mapping Page
opens.
A new class map is added by selecting one or two ACLs and giving the class map
a name. If a class map has two ACLs, you can specify that a frame must match
both ACLs, or that it must match either one or both of the ACLs selected.
STEP 3 Enter the parameters.
• Class Map Name—Enter the name of a new class map.
• Match ACL Type—The criteria that a packet must match in order to be
considered to belong to the flow defined in the class map. The options are:
- IP—A packet must match either of the IP based ACLs in the class map.
- MAC—A packet must match the MAC based ACL in the class map.
- IP and MAC—A packet must match the IP based ACL and the MAC
based ACL in the class map.
- IP or MAC—A packet must match either the IP based ACL or the MAC
based ACL in the class map.
• IP—Select the IPv4 based ACL or the IPv6 based ACL for the class map.
