24 Quality of Service Commands
The commands described in this section are used to configure Differentiated
Services (DiffServ) classification criteria and service policies. You can classify traffic
based on access lists, IP Precedence or DSCP values, or VLANs. Using access lists
allows you select traffic based on Layer 2, Layer 3, or Layer 4 information contained
in each packet.
