Licensing Requirements

MQC provides three command types to define traffic classes and policies:
• class-map—Defines a class map that represents a class of traffic based on packet-matching criteria. Class
• table-map—Defines a table map that represents a mapping from one set of packet field values to another
• policy-map—Defines a policy map that represents a set of policies to be applied on a class-by-class basis
You define the following class-map and policy-map object types when you create them:
• network qos—Defines the characteristics of CoS properties network wide (across switches and VDCs).
• qos—Defines MQC objects that you can use for marking and policing.
• queuing—Defines MQC objects that you can use for queuing and scheduling.
You can attach policies to ports, port channels, VLANs, subinterfaces, or tunnels by using the service-policy
command.
On Fabric Extender (FEX) interfaces, you can configure only the type qos policies. However, you cannot
configure the type qos policies that refer to classes that match with the access control lists (ACLs) that are
configured for the FEX external interfaces.
The type queuing policies are currently not supported on FEX interfaces.
You can view all or individual values for MQC objects by using the show table-map, show class-map, and
show policy-map commands.
Caution
In interface configuration mode, the Cisco Nexus 7000 Series switch might accept QoS and ACL commands
irrespective of the line card on which the interface host is up or down. However, you cannot enter interface
submode when the line card is down because the Cisco Nexus 7000 Series switch does not accept any
preconfiguration information.
Licensing Requirements
The QoS feature does not a require license. Any feature not included in a license package is bundled with the
Cisco NX-OS system images and is provided at no extra charge to you.
Using virtual device contexts (VDCs) requires an Advanced Services license.
