QoS configuration under NETCONF overview

This chapter provides procedures for configuring QoS and Auto QOS using the NETCONF interface.
Refer to the Network OS Administrator’s Guide for an explanation of related concepts and
presentation of default values.

Standalone QoS

Standalone Quality of Service (QoS) provides you with the capability to control how the traffic is
moved from switch to switch. In a network that has different types of traffic with different needs
(also known as CoS), the goal of QoS is to provide each traffic type with a virtual pipe. FCoE uses
traffic class mapping, scheduling, and flow control to provide quality of service.

The

“Queueing”

,

“Congestion control”

,

“Multicast rate limiting”

,

“Scheduling”

, and

“Data Center

Bridging map configuration”

sections of this chapter provide procedures for configuring and

managing QoS in standalone mode. Refer to the Network OS Administrator’s Guide for
explanations of these standalone QoS concepts.
