An ACL-based traffic group allows you to use ACL rules in an ACL policy file to define the traffic to which you want to apply QoS. An ACL-based traffic group requires more effort to create, but the ACL rules give you more control over which traffic is selected for the traffic group. For example, you can use an ACL to add traffic to a traffic group based on the following frame or packet components:
Depending on the platform you are using, traffic in an ACL traffic group can be processed as follows:
When you are deciding whether to use an ACL-based traffic group or another type of traffic group, consider what QoS features you want to apply to the traffic group. Some QoS features can only apply to ACL-based traffic groups.
NoteACLs are discussed in detail in the ACLs chapter.
