top toolbar of the Cisco SDM window. Step 2 Click Quality of Service in the Tasks toolbar at the left side of the Cisco SDM window. Step 3 Click the Create QoS Policy tab. Step 4 Click the Launch QoS Wizard button to launch the wizard. Figure shows the QoS Wizard screen. Step 5 Cisco SDM QoS Wizard informs you that it will configure two classes: real-time and business-critical. Click Next to proceed. Step 6 Figure shows you how to select an interface. You are asked to select an interface that you want a QoS policy applied to. Click Next to proceed. Step 7 The QoS Policy Generation screen (Figure ) prompts you to enter the bandwidth percentages for each class. After you enter the numbers, Cisco SDM automatically calculates the best-effort class and the bandwidth requirements for each class. Click Next to proceed to the Summary screen and review the QoS configuration.
Content 3.5 Implementing QoS with Cisco SDM QoS Wizard 3.5.3 Reviewing the QoS Configuration Before delivering the configuration to the router, review the QoS configuration summary. In the Summary window, Cisco SDM shows the QoS configuration that was configured. Review the QoS configuration carefully to ensure that there are no errors since the wizard applies this configuration to your router once you click the Finish button. Figures and present the settings for the SDMVoice-FastEthernet0/1, SDMVideo-FastEthernet0/1, SDMSignal-FastEthernet0/1, and SDMSVideo-FastEthernet0/1 classes. Figures and present the settings for the SDMTrans-FastEthernet0/1, SDMManage-FastEthernet0/1, SDMRout-FastEthernet0/1, and SDMBulk-FastEthernet0/1 classes. Figure presents the settings that will be applied with the SDMScave-FastEthernet0/1 class. The last step is to click Finish to deliver the configuration to the router. The Commands Delivery Status window shown in Figure shows the progress of the delivery of the configuration to the window. When the window tells you that the commands have been delivered to the router, click OK to complete your configuration.
Content 3.5 Implementing QoS with Cisco SDM QoS Wizard 3.5.4 Monitoring QoS Status After QoS is configured, you can use the following steps to monitor its status as shown in Figure : Step 1 To enter monitor mode, click the Monitor icon in the toolbar at the top of the Cisco SDM window. Step 2 Click QoS Status in the Tasks toolbar at the left side of the Cisco SDM window. The traffic statistics appear in bar charts based on the combination of the selected interval and QoS parameters for monitoring as follows:
Content 3.6 Introduction QoS Lab Exercises 3.6.1 Lab 3.1 Preparing for QoS Lab Activity Lab Exercise: Lab 3.1 Preparing for QoS The Quality of Service (QoS) labs for Modules 3, 4, and 5 have been designed to rely on traffic generation and measuring tools for testing purposes. Traffic generation will be used to create streams of traffic that will flow through your network unidirectionally.

These labs will use the Cisco Pagent image and toolset for the QoS labs in the QoS modules. Pagent is a set of traffic generation and testing tools that runs on top of a Cisco IOS image. Booting a router with Pagent can be done by acquiring the image through the Cisco Networking Academy program, loading it into the router’s flash memory, and entering a license key when prompted during system boot.

When using the lab configurations it will be necessary to load the Pagent image on R4. This lab guides you through creating configurations for the QoS labs.
Content 3.6 Introduction QoS Lab Exercises 3.6.2 Lab 3.2 Installing SDM Lab Activity Lab Exercise: Lab 3.2 Installing SDM In this lab, you will prepare a router for access via the Cisco Security Device Manager (SDM), using some basic commands, to allow connectivity from the SDM to the router. You will then install the SDM application locally on a host computer. Finally, you will install SDM onto the flash memory of a router.
Content 3.6 Introduction QoS Lab Exercises 3.6.3 Lab 3.3 Configuring QoS with SDM Lab Activity Lab Exercise: Lab 3.3 Configuring QoS with SDM Cisco Security Device Manager employs a basic Quality of Service (QoS) configuration wizard that can be used to apply some basic QoS tools to a router’s interfaces. Normally, you would configure and deploy QoS tools on the command-line interface (CLI) without the benefit of a graphical user interface (GUI). However, SDM’s QoS wizard provides a useful introduction to QoS tools. Thus, we begin our exploration of QoS tools using the SDM GUI.
Content Summary This module describes the difference between nonconverged and converged networks and how converged IP networks can suffer from poor quality of service (QoS) for several reasons, including low bandwidth, excessive delay, jitter, and packet loss. The module explains the steps used to implement Cisco IOS QoS and how implementing QoS decreases the effect of poor QoS factors with the use of queuing, compression, prioritization, and link efficiency mechanisms. The three basic QoS models, best effort, Integrated Services (IntServ), and Differentiated Services (DiffServ) are defined: The best-effort model does not provide any QoS, while the IntServ model relies on applications signaling QoS requirements to the network, and DiffServ is the most scalable model for implementing the QoS required for modern converged networks. The four different implementation techniques for QoS are the legacy command-line interface (CLI) method used for basic QoS deployments, the Modular QoS CLI (MQC) for high-level deployments and QoS fine-tuning, Cisco AutoQoS for general QoS setups, and Cisco Router and Security Device Monitor (SDM) QoS wizard, a web-based application for QoS deployments in the enterprise environment.
