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.
