QoS Features and Components

Cisco Small Business 200 Series Smart Switch Administration Guide
The Quality of Service feature is applied throughout the network to ensure that
network traffic is prioritized according to required criteria and the desired traffic
receives preferential treatment.
This chapter contains the following topics:
• QoS Features and Components
• Configuring QoS
• Managing QoS Statistics
The QoS feature is used to optimize network performance.
QoS provides the following:
• Classification of incoming traffic to traffic classes, based on attributes,
including:
- Device Configuration
- Ingress interface
- Packet content
- Combination of these attributes
QoS includes the following:
• Assignment to Hardware Queues—Assigns incoming packets to
forwarding queues. Packets are sent to a particular queue for handling as a
function of the traffic class to which they belong.
• Other Traffic Class-Handling Attribute—Applies QoS mechanisms to
various classes, including bandwidth management.
