Dell EMC SmartFabric OS10 User Guide Release 10.5.0

• qos (default)—Classifies ingress data traffic.
• queuing —Classifies egress queues.
• control-plane—Classifies control-plane traffic.
• network-qos—Classifies traffic-class IDs for ingress buffer configurations.
• application —Classifies application-type traffic. The reserved policy-map policy-iscsi defines the actions for class-iscsi traffic.

• qos (default)—Defines the following actions on the traffic classified based on qos class-map:
  • Policing
  • Marking with a traffic class ID
  • Modifying packet fields such as CoS and DSCP
• queuing —Defines the following actions on the egress queues classified based on queuing class-map:
  • Shaping
  • Assigning bandwidth for queues
  • Assigning strict priority for queues
  • Buffering configuration for queues
  • Weighted random early detection (WRED)/Explicit congestion notification (ECN) configuration on queues
• control-plane—Defines the policing of control queues for rate-limiting the control-plane traffic on CPU queues.
• network-qos—Defines the Ingress buffer configuration for selected traffic-classes matched based on network-qos class-map.
• application —Defines the following actions for the application classified traffic:
  • Modifying packet fields such as CoS and DSCP.
  • Marking traffic class IDs.

• Apply control-plane polices in Control-Plane mode.
• Apply QoS and network-QoS policies in the input direction on physical interfaces or in System-QoS mode.
• Apply queuing policies in the output direction on physical interfaces or in System-QoS mode.
• Apply an application type policy-map in System-QoS mode.

When you apply a policy at the system level (System-QoS mode), the policy is effective on all the ports in the system. However, the interface-level policy takes precedence over the system-level policy.
