Type Qos Policies; Type Queuing Policies - Cisco Nexus 9000 Series Configuration Manual

Using Modular QoS CLI
A policy map contains either a QoS policy or queuing policy. The policy map references the names of class
maps that represent traffic classes. For each class of traffic, the device applies the policies on the interface or
VLAN that you select.
A packet is matched sequentially to a class of traffic starting from the first traffic class definition. When a
match is found, the policy actions for that class are applied to the packet.
The reserved class map class-default receives all traffic that is not matched in type qos policies, and the device
applies the policy actions as it would for any other traffic class.

Type qos Policies

You use type qos policies to mark and to police packets, and to set qos-groups, which drive matching conditions
for system-defined type network-qos and type queuing class-maps.
The following figure shows the QoS policy structure with the associated MQC objects of type qos. The MQC
objects are shown in bold.

Type Queuing Policies

You use type queuing policies to shape and queue packets.
The following figure shows the QoS policy structure with associated MQC objects of type queuing. The MQC
objects are shown in bold.
