Using Classifier-Based Service Policies
Using Classifier-Based Service Policies
Introduction
Classifier-based service policies are designed to work with existing globally-
configured, switch-wide and port-wide configurations by allowing you to
zoom in on a subset of port or VLAN traffic to further manage it. These policies
take precedence over, and may override, globally-configured settings.
Classifier-based service policies provide greater control for managing net-
work traffic. Using multiple match criteria, you can finely select and define
the classes of traffic that you want to manage. Policy actions determine how
you can handle the selected traffic.
Starting in software release K.14.01, the Classifier feature introduces:
■ A finer granularity than globally-configured features for classifying net-
work traffic (IPv4 or IPv6) into classes that can be used in cross-feature
software configurations
■ Additional policy actions to manage selected traffic, such as rate-limiting
and IP precedence marking
■ The configuration of service policies for classified traffic with the follow-
ing software features:
• Quality of Service (QoS)
• Traffic mirroring
■ The application of service policies to specific inbound traffic flows on
individual port and VLAN interfaces (rather than only on switch-wide or
port-wide traffic).
