Price: £695 (ex. VAT)

The introduction of new technologies and applications into modern converged networks brings a new set of challenges to the network administrator. In this course, you will learn the characteristics of real-time multimedia traffic, such as voice, and you'll investigate the importance of Quality of Service (QoS) management on the network and learn about the application of wireless technologies to the enterprise. Get an introduction to Cisco's Lightweight Wireless Access Point architecture, and cover such areas as Wireless LAN (WLAN) configuration, QoS for wireless, and wireless security techniques for authentication and data encryption. You will also explore the management of WLAN Controllers across the enterprise using Cisco's Wireless Control System.
 
This package includes access to Self Test Software's exam prep products and one FREE exam voucher.

Labs

Lab 1: ONT Lab Setup and Initialization

Prepare the pod for the remaining lab practice exercises in the course.

  • Configure pod routers for basic network connectivity.
  • Verify network connectivity using the Cisco IOS ping commands.

Lab 2: Placing and Examining VoIP Calls

Place VoIP calls with different codecs and examine call status information and statistics of the IP packets that are exchanged between the workstations.

  • Configure CIPC, a software phone application that is installed on a virtual workstation to register with CME, a call agent that runs on an IOS router.
  • Place a call from one workstation to another using CIPC with the default codec (G.711). Display voice call statistics on the CIPC screen and obtain network and call information by browsing to the web server of CIPC. Capture RTP packets and analyze them using Ethereal, a network protocol analyzer software.
  • Reconfigure CIPC to register with CME using a different device name configured for a different codec (G.729).
  • Place a call from one workstation to another using CIPC with the G.729 codec. Use the same tools used on the previous call to note the differences caused by the codec change.
  • Exclusive: Twice as many phones per pod as the standard lab, allowing complete pod independence

Lab 3: Case Study: Selecting a Converged Network Strategy

Identify the type of QoS problem in progress and suggest a possible solution to mitigate the QoS problem.

  • Identify bottlenecks and performance losses in the network.
  • Recommend appropriate QoS actions to mitigate specific performance issues.

Lab 4: Introducing MQC and the SDM QoS Wizard

Use the MQC to configure a basic service policy and launch the SDM QoS wizard.

  • Connect to the equipment and configure the basic MQC components.
  • Launch SDM QoS wizard.

Lab 5: Configuring NBAR

  • Discover network applications and traffic using NBAR protocol discovery.
  • Configure classification of discovered applications using NBAR classification.
  • Configure class-based marking.

Lab 6: Configuring FIFO and WFQ Queuing Mechanisms

  • Configure FIFO queuing on Cisco routers.
  • Configure WFQ queuing on Cisco routers.
  • Interpret output of show interface command to monitor and verify the FIFO and WFQ operation on the serial lines.

Lab 7: Configuring LLQ Queuing Mechanism

  • Configure LLQ on a Cisco router to provide bandwidth guarantees.
  • Use the proper show commands to monitor and verify the LLQ.
  • Use Cisco IOS monitoring commands and network connectivity tools (ping) to gather network response time data.

Lab 8: Class-Based Header Compression

  • Configure class-based RTP header compression on a PPP link.
  • Monitor the operation of class-based RTP header compression.

Lab 9: Configuring LFI

Configure and monitor MLP with interleaving on a PPP link. The generated traffic will be interleaved on the MLP link according to the predefined policy map. Ping will be used to test the PPP connectivity.

  • Configure LFI on PPP WAN links.
  • Monitor the operation of link fragmentation and interleaving.

Lab 10: Configuring QoS Pre-Classify

  • Configure QoS pre-classify on a Cisco IOS router using a GRE tunnel.
  • Monitor QoS pre-classify configurations.

Lab 11: Configuring QoS with Cisco AutoQoS

  • Activate the AutoQoS Discovery on the pod router to perform traffic analysis on low bandwidth PPP serial interface.
  • Enable the AutoQoS for Enterprise feature on the pod router low bandwidth PPP serial interface.
  • Use Cisco IOS monitoring commands and network connectivity tools (ping) to gather network response time data.

Lab 12: Using MQC to Tune QoS Mechanisms Configured With AutoQoS

Revise the AutoQoS configuration from Lab 11 by tuning classification using MQC and marking using class-based marking.

  • Configure MQC classification.
  • Configure class-based marking.

Lab 13: Troubleshooting Converged Networks

Troubleshoot a converged network in order to bring it back to total functionality. Use several show commands to solve these problems:

  • Layer 1 and Layer 2 troubleshooting
  • IP routing
  • QoS troubleshooting

Lab 14: Setting Up the Wireless LAN Controller

Create a basic configuration for the wireless LAN controller. The purpose of this lab is to establish initial connectivity to the controller through the console, become familiar with the startup wizard that runs on initial startup, and complete the necessary steps to establish a SSL web connection to the controller. In this activity, we create the initial configuration of the wireless LAN controller, using the CLI and continue with additional configuration steps using the GUI.

  • View CLI and GUI configuration options.
  • Input basic configuration information using CLI.
  • Configure WLC using GUI.

Lab 15: Basic Security Configuration Using WPA-PSK

WEP key encryption is not secure. Therefore the majority of new clients are supporting WPA-PSK authentication. In this lab exercise, configure a new WLAN ID on the WLC using WPA-PSK, and test the configuration by monitoring client association to the AP.

  • Configure WPA-PSK on WLC.
  • Monitor your configuration.

Lab 16: Advanced Security Configuration Using LEAP Server-Based Authentication

WEP key encryption is not secure enough and WPA-PSK improvements are the first step to improve wireless security. The next step is to enhance security by using server-based authentication. Cisco wireless LAN controllers support a wide range of different client to server-based authentication types. In this lab exercise, configure the authentication for client association using LEAP. After configuration, verify the LEAP authentication by monitoring clients associated to the AP.

  • Configure LEAP server-based authentication on WLC.
  • Monitor your configuration.
  • Enhanced: Cisco 7920 wireless phones used as clients to test LEAP authentication

Lab 17: Configuring Wireless Control Systems (WCS) for WLANs

The WCS provides centralized management of WLCs and their associated APs. In this lab, connect to the WCS, add the WLAN controller, review the status, add maps to the WCS, and place APs on the map.

  • Login to the WCS.
  • Configure the WCS and check the status.
