Defining QoS 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.
Use the
QoS Class Map page to enable assigning and editing class maps. To open the page, click
Quality of Service
→ Advanced QoS Mode → Class Map in the tree view.
