Classifier-Based Software Configuration
Introduction
Classifier-based service policies are designed to work with existing globally 
configured switch-wide and port-wide settings by allowing you to select a 
subset of:
■ Traffic sent to or from certain ports 
■ VLAN traffic 
Once the traffic is selected, you can further manage it. 
Classifier-based service policies take precedence over, and may override, 
globally configured settings. These policies provide greater control for man-
aging network traffic. Using multiple match criteria, you can finely select and 
define the classes of traffic that you want to manage. You can then use policy 
actions to determine how the selected traffic is handled.
Classes can be based on IPv4 or IPv6 addresses (which you specify in the 
policy). For information about traffic classes, see “Traffic Classes” on page 8-2.
When you are using an HP AllianceONE Extended Services zl Module that 
supports Transparent Mode, you can also classify traffic based on zones. For 
information about zone classes, see “Zone Classes” on page 8-39.
