Information About Fabric QoS Mapping

The Fabric QoS Mapping feature allows copying the default configuration and modifying the copied system
queues that perform flow control on fabric traffic within the Cisco NX-OS device, thus enabling the choice
of parameters for fabric queuing based on the network, traffic, and requirements for traffic prioritization.
Note
Default policies cannot be modified. The user-defined policies configured on the fabric cannot be modified.
Fabric queuing policies are controlled by COS-to-queue (cos2q) mappings, ingress queuing policies, and
egress queuing policies applied on the QEngine of M1 and M2 line cards.

COS-to-Queue Fabric Mapping

The following are the four system-defined queues available for cos2q mapping:
• system-pq1
