Defining Class Mapping
The Class Mapping Page contains parameters for defining 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 to 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.
STEP 1 Click Quality of Service > Advanced Mode > Class Mapping. The Class Mapping
Page
opens:

ACL’s address. The possible field values are:
- And — Both the MAC-based and the IP-based ACL must match a
packet.
- Or — Either the MAC-based or the IP-based ACL must match a packet.
• ACL2 — Contains a list of the user-defined ACLs.
