Overview

Module 1: Introduction to IP QoS

• Given a description of a converged network, identify problems that could lead to poor quality of service and explain how the problems might be resolved

• Define the term Quality of Service (QoS) and identify and explain the key steps to implementing QoS on a converged network

• Given a need to implement QoS on a network, list and describe methods for implementing QoS

Module 2: The Building Blocks of IP QoS

• Given a list of QoS actions, correctly match each action to one or more of the models for implementing QoS on a network

• Given a network requiring different levels of service, describe the Differentiated Services model and explain how it can be used to implement QoS in that network

• Given a list of QoS actions, correctly match the QoS actions to mechanisms for implementing QoS and identify where in a network the different QoS mechanisms are commonly used

• Given a diagram of a converged network, correctly identify the QoS status of packets as they pass through various points in the network

Module 3: Introduction to Modular QoS CLI and Auto-QoS

• Given a network requiring QoS, explain how to implement a QoS policy using MQC

• Correctly identify capabilities provided by AutoQoS, and, given a network with QoS issues, successfully configure QoS on a network using AutoQoS

Module 4: Classification and Marking

• Given a network requiring QoS, explain the purpose of classification and marking and how they can be used to define a QoS service class

• Given a network and a description of QoS issues, use MQC CLI commands to classify packets

• Given a network and a description of QoS issues, use class-based marking to assign packets to a specific service class

• Given a network and a description of QoS issues, use Network Based Application Recognition (NBAR) to discover network protocols and applications, and to classify packets

• Given a virtual private network, use the QoS pre-classify feature to classify GRE, IPSec, L2F and L2TP encapsulated packets

• Given an interdomain network and a description of QoS issues, explain how to implement classification and marking using QPPB

• Given a local area network and a description of QoS issues, describe LAN-based methods for implementing classification and marking

Module 5: Congestion Management

• Given a block diagram showing the queuing components of a Cisco router, describe the functions of hardware and software queuing

• Given a set of QoS requirements, explain when it would be appropriate to use FIFO, PQ, and/or CQ to manage congestion

• Given a network with sub-optimal QoS performance, configure Weighted Fair Queuing to manage congestion

• Given a network with sub-optimal QoS performance, configure Modified Deficit Round Robin to manage congestion

• Given a network with sub-optimal QoS performance, configure CBWFQ and LLQ to manage congestion

• Given a network with sub-optimal QoS performance, configure WRR on a Catalyst switch to manage LAN Congestion.

Module 6: Congestion Avoidance

• Explain the problems that may result from the limitations of TCP congestion management mechanisms on a converged network

• Given a TCP/IP network, explain how Random Early Detection (RED) can be used to avoid congestion

• Given a TCP/IP network, configure Class-Based Weighted RED (CB-WRED) to avoid congestion

• Given a TCP/IP network, configure Explicit Congestion Notification (ECN) to enhance the congestion avoidance features of Weighted RED (WRED)

Module 7: Traffic Policing and Shaping

• Given a description of a network with QoS issues, explain how traffic policing and traffic shaping can be used to rate limit traffic

• Given a network, configure Class-Based Policing to rate limit traffic

• Given a network, configure Class-Based Shaping to rate limit traffic

• Given a FR WAN link, configure Class-Based shaping on the FR interface to rate limit traffic.

Module 8: Link Efficiency Mechanisms

• Given a description of a network with QoS issues, explain how link efficiency mechanisms can be used to improve bandwidth efficiency and reduce delay

• Given a description of a network, explain how payload compression can be used to improve bandwidth efficiency and reduce delay

• Given a network, configure class-based TCP and class-based RTP header compression to improve

• bandwidth efficiency and reduce delay

• Given a network, configure Link Fragmentation and Interleaving (LFI) to improve bandwidth efficiency and reduce delay

Module 9: QoS Best Practices

• Given a description of different network traffic types, correctly identify and describe the set of classification practices that most closely represent Cisco’s QoS “best practices”

• Given a description of a typical service provider network, correctly identify and describe the set of QoS mechanisms used to implement Cisco’s QoS “best practices”

• Given a description of a typical enterprise network, correctly identify and describe the set of QoS mechanisms used to implement Cisco’s QoS “best practices”

Prerequisites

The student should possess work experience and configuration skills for Cisco routers and LAN switches. These skills are best demonstrated through the Cisco career certification Cisco Certified Networking Associate (CCNA). Previous exposure to internal routing protocols and LAN/WAN technologies allows the student to fully benefit from the topics discussed in various parts of the curriculum.
