Information About QoS

The Cisco Nexus 5000 Series switch provides QoS capabilities such as traffic prioritization and egress
bandwidth allocation.
The default QoS configuration on the switch provides lossless service for Fibre Channel and Fibre
Channel Over Ethernet (FCoE) traffic and best-effort service for Ethernet traffic. QoS can be configured
to provide additional classes of service for Ethernet traffic. Cisco Nexus 5000 Series QoS features are
configured using Cisco Modular QoS CLI (MQC).
