Wireless Media Access (and VLANs)
00:34:49
This nugget really gets under the hood at the actual behavior of 802.11 frames. Topics covered in this lesson include: wireless frame types and IFS periods, basic frame transmission, wireless frame headers, a survey of wireless frames, some wireless road trips, and using VLANs for wireless.
 
Discovery and Association, Operational Modes and Roaming
00:26:16
Here's an action-packed nugget for you. Lets learn all about LWAPP modes, wireless LAN controller discovery and joining, mobility groups, and roaming at layer 2 and at layer 3!
 
Configuring the Cisco 4400 Series Wireless LAN Controller
00:33:46
Let's get some hands-on demonstation of the 4402 WLC. We'll explore ports and interfaces, the 4402/4404 command-line-interface, initial configuration and setup, and survey the web-based GUI configuration manager for the controller.
 
Controller-Based Network Management
00:28:02
This nugget is a continuation of the previous nugget as we investigate monitoring the network through the controller, monitoring and managing APs, monitoring rogues, client monitoring and management, as well as internal DHCP scope configuration.
 
Configuring Standalone Access Points
00:30:19
Now is your chance to learn how to connect to a standalone AP, use the express setup web interface, perform setup of security setup, and converting to LWAPP mode.
 
Wireless Mobility Express
00:24:08
This nugget explores the small business solution from Cisco known as the Cisco Mobility Express. We look at product options for the initiative, the 521 WL Express Lightweight AP, the 526 Mobility Express Controller, setting up the solution through the CLI, and using the web-based GUI management tool.
 
Wireless Clients
00:33:03
This important CCNA wireless nugget covers common operating system configuration utilities, the Cisco ADU, Cisco ACAU, and the Cisco SSC Supplicant.
 
WLAN Security (Part 1)
00:45:16
Here is one of the most vital aspects of wireless networking - security. This first security module addresses threats to wireless networks, an overview of WLAN security, establishing 802.11 security, centralized authentication, and Local EAP.
 
WLAN Security (Part 2)
00:38:17
This is a continuation of part one where the following protocols are covered: EAP-TLS, EAP-FAST, PEAP, and WPA/WPA2. Finally, the topic of configuration on WLC and the client is covered.
 
Cisco WCS Administration
00:20:43
You'll find this examination of the WCS really interesting. Learn how wireless enterprises are managed and monitored. Understand the benefits of WCS and the Locator Appliance.

Cisco retired its 642-721 exam on May 11, 2012. However, this training retains considerable value as an IT resource. Training for the new 640-722 exam can be found here.

It seems like the whole world is going wireless. After watching Michael Shannon's CCNA Wireless training series you'll be ready to control wireless technology.

Michael's training is appropriate for anyone considering implementing a Cisco Wireless solution for their company, a partner, their customer, or their clients...even if its simply for a guest or lobby VLAN. In addition, anyone who needs to setup a wireless LAN for scenarios like a hotel, airport, retail site, or medical facility will find this training invaluable.

Soon you'll be ready to deploy your own stand-alone or LWAPP wireless LAN and use the CLI or graphical web-based tools to configure your solution. You'll also be well prepared for the CCNA Wireless exam and gain solid grounding towards respected Cisco CCNP Wireless certification.
