Creating Class Maps
One IP ACL and/or one MAC ACL comprise a class map. Class maps are configured to match packet criteria, and
are matched to packets on a first-fit basis. For example, Class Map A is assigned packets based only on an IP-
based ACL or a MAC-based ACL. Class Map B is assigned to packets based on both an IP-based and a MAC-
based ACL. To define class maps:
1. Click Advanced Setup > Quality of Service > Policy Properties> Class Map . The Class Map Page opens:
Figure 207: Class Map Page
The Class Map Page contains the following fields:
•
Class-Map Name — Displays the user-defined name of the class map.
•
Preferred ACL — Indicates if packets are first matched to an IP based ACL or a MAC based ACL.
•
ACL 1 — Contains a list of the user defined ACLs.
•

•
Remove — Removes Class Maps. The possible field values are:
–
Checked — Removes the selected Class Maps.
–
Unchecked — Maintains the current Class Maps.
