Licensing Requirements; Prerequisites For Mutation Mapping - Cisco Nexus 7000 Series Configuration Manual

Licensing Requirements

Note The device supports hierarchical policies only for mutation mapping.
The sequence of QoS actions on ingress traffic is as follows:
1. Queuing and scheduling
2. Mutation
3. Classification
4. Marking
5. Policing
The sequencing of QoS actions on egress traffic is as follows:
1. Classification
2. Marking
3. Policing
4. Mutation
5. Queuing and scheduling
Note Mutation occurs much closer to the beginning of the traffic actions on the ingress packets, and any further
classification and policing is based on the changed QoS values. Mutation occurs at the end of the traffic actions
on the egress packets, right before queuing and scheduling.
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.
For a complete explanation of the Cisco NX-OS licensing scheme, see the Cisco NX-OS Licensing Guide.

Prerequisites for Mutation Mapping

Mutation mapping has the following prerequisites:
• You must be familiar with the "Using Modular QoS CLI" section.
• You are logged on to the switch.
• You are in the VDC. A VDC is a logical representation of a set of system resources. You can use the
Cisco Nexus 7000 Series NX-OS Quality of Service Configuration Guide
60
switchto vdc command with a VDC number.
