Module 11
Troubleshooting, Management, Monitoring, and Diagnostics
© 2003, Cisco Systems, Inc. All rights reserved. FWL 1.0—11-3
Overview
This module will cover the basics of troubleshooting. It begins by examining a methodology that breaks down the process of troubleshooting into manageable steps. Next, a variety of tools will be introduced that are used to troubleshoot a WLAN. These tools include cable testers, sniffers, and spectrum analyzers. A brief discussion of system logging and single point of failure troubleshooting will be presented. Finally, enterprise management tools will be explored.

Wireless LAN Challenges
The lack of effective management has inhibited the growth of large-scale wireless networks due to . . .• The challenge of configuring hundreds or
thousands of access points
• Security risks opened up by mis-configurations
• Lack of sufficient tools for trouble shooting, performance analysis and capacity planning
