22Quality 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.
