Dell EMC SmartFabric OS10 User Guide Release 10.5.1

Ingress traffic classification

Ingress traffic can either be data or control traffic.

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.

By default, OS10 does not classify data traffic. OS10 assigns the default traffic class ID 0 to all data traffic.

OS10 implicitly classifies all control traffic such as STP, OSPF, ICMP, and so on, and forwards the traffic to control plane applications. See Control-plane policing for more information.
