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 Advance Setup > Quality of Service > Policy Properties> Class Map. The Class Map Page opens:
Figure 165: Class Map Page
The Class Map Page contains the following fields:
• Class-Map Name — Displays the user-defined name of the class map.

• ACL 1— Contains a list of the user defined ACLs.
• Match — Indicates the criteria used to match class maps with an ACL’s address. Possible values are:
– And — Matches both ACL 1 and ACL 2 to the packet.
– Or — Matches either ACL 1 or ACL 2 to the packet.

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