Configuring QoS is a three-step process: 1 Create class-maps to classify the traffic flows. The following are the different types of class-maps: • qos (default)-Classifies the ingress data traffic. • queuing -Classifies the egress queues. • control-plane-Classifies the control-plane traffic. • network-qos-Classifies the set of traffic-class IDs for ingress buffer configurations. • application -Classifies the application type traffic. The reserved policy-map policy-iscsi defines the actions to be performed for class-iscsi traffic. 2 Create policy-maps to define the policies for the classified traffic flows. The following are the different types of policy-maps: • 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 - Enabling trust based classification • queuing -Defines the following actions on the egress queues classified based on queuing class-map. - Shaping - Bandwidth assignment for queues - Strict priority assignment for queues - Buffer configuration for queues - WRED 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. - Modify packet fields like CoS and DSCP. - Mark with a traffic class ID. 3 Apply the policy-maps to interface (port), system (all interfaces), or control-plane traffic as follows: • Control-plane polices must be applied on control-plane mode. • The qos and network-qos policies must be applied in the input direction on physical interfaces or on system-qos mode.
