QoS model
This section explains the implementation and configuration details of QoS:
Traffic types
Data — Packets can be network-to-network traffic or traffic from CPU. Network-to-network packets are considered data traffic and QoS parameters can be applied on data traffic.
Control — Packets to and from the CPU are considered as control traffic. Incoming control traffic is prioritized based on ingress map and are sent to their own designated CPU queues. Each CPU queue has a fixed rate limit to guard the CPU. Outgoing control traffic will always be sent on highest priority queue (Q7) on the data port.
Setting packet header QoS fields
The device supports modifying the packets header IEEE 802.1p user priority or IP-DSCP.
