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.
