Table Of Contents
Different QoS features control the traffic flow parameters, as the traffic traverses a network device from ingress to egress
interfaces.
Classification
To prioritize traffic, you must first classify it. Classification is the process that differentiates one type of traffic from another
and categorizes it in to different groups.
OS10 groups network traffic into different traffic classes, from class 0 to 7 based on various parameters. Grouping traffic into
different classes helps to identify and prioritize traffic as it goes through the switch.
NOTE: Traffic class is also called as QoS group.
Ingress traffic can either be data or control traffic. By default, OS10 does not classify data traffic. OS10 assigns the default
traffic class ID 0 to all data traffic.
You can classify traffic based on:
● Access control lists (ACLs)
● Class of Service (CoS) at L2
● Differentiated Services Code Point (DSCP) at L3
