Configuring Quality of Service

This section provides information for defining and configuring Quality of Service (QoS) parameters. To 
open the Click

 Quality of Service 

in the tree view.

Quality of Service

 

(QoS) provides the ability to implement QoS and priority queuing within a network. 

QoS improves network traffic flow based on policies, frame counters and context. 
An implementation example that requires QoS include certain types of traffic such as Voice, Video and 
real-time traffic which can be assigned a high priority queue, while other traffic can be assigned a lower 
priority queue. The result is an improved traffic flow for traffic with high demand.
QoS is defined by:

•

Classification

 — Specifies which packet fields are matched to specific values. All packets matching 

the user-defined specifications are classified together.

•

Action

 — Defines traffic management where packets being forwarded are based on packet 

information, and packet field values such as VLAN priority (VPT) and DSCP (DiffServ Code Point).

VPT Tag Classification Information

VLAN Priority Tags are used to classify the packets by mapping packets to one of the output queues. 
VLAN Priority Tag to queue assignments are also user-definable. The table below details the VPT to 
queue default settings:
