Quality of Service (QoS) - amybuck/SONiC-NAS GitHub Wiki

QoS support:

• Assign packet to traffic classes using packet 802.1p, DSCP or more advanced ACL rules
• Marking
• Ingress rate policing using ACLs
• Map traffic classes to queues
• Egress Queue rate shaping
• Weighted random early detection (WRED)
• Hierarchical scheduling
• Egress Port-level shaping
• CoPP support for configuring CPU rate-limits

NOTE: The SONiC NAS Host-Adapter does not support QoS configuration using Linux commands — use the dell-base-qos.yang model.

See Application Programming for SONiC for information about how to use dell-base-qos.yang and the SONiC Object Library API for QoS applications.
