Advanced classifier-based QoS

Starting in software release K.14.01, the packet classification and prioritization methods for QoS also support classifier-based functions. Advanced classifier-based QoS introduces:

  • A finer granularity than globally-configured QoS for classifying IPv4 and IPv6 traffic

  • Additional actions for managing selected traffic, such as rate limiting and IP precedence marking

  • The application of QoS policies to inbound traffic flows on specific port and VLAN interfaces (instead of using only globally-configured, switch-wide QoS settings)

  • Enables reusable traffic classes in different software-feature configurations, such as QoS and port mirroring

Classifier-based QoS is designed to work with existing globally-configured, switch-wide QoS policies by allowing you to zoom in on a subset of port or VLAN traffic to further manage it. Classifier-based policies take precedence over, and may override, globally-configured QoS settings that apply to all traffic on the switch.

Classifier-based QoS policies provide greater control for managing network traffic. Using multiple match criteria, you can finely select and define the classes of traffic that you want to manage. QoS-specific policy actions determine how you can handle the selected traffic.
