Implementing Cisco Quality of Service v2.3 - QoS

Implementing Cisco Quality of Service v2.3 - QoS Course Description

Duration: 5.00 days (40 hours)

Cisco Career Guide

QoS: Implementing Cisco Quality of Service v2.3 provides learners with in-depth knowledge of quality of service (QoS) requirements, conceptual models such as best effort, Integrated Services (IntServ) and Differentiated Services (DiffServ), and the implementation of QoS on Cisco IOS platforms. The curriculum covers the theory of QoS, design issues, and configuration of various QoS mechanisms to facilitate the creation of effective administrative policies providing QoS.

Case studies and lab exercises included in the course help learners to apply the concepts mastered in individual modules to real-life scenarios. The course also gives learners design and usage rules for various advanced QoS features and the integration of QoS with underlying Layer 2 QoS mechanisms. This gives learners the opportunity to design and implement efficient, optimal, and trouble-free multiservice networks.

Upon completion of this course, the learner will be able to identify, describe, and correctly implement the appropriate QoS mechanisms that are required to create an effective administrative policy providing QoS.
