2. Troubleshooting, Management, Monitoring, and Diagnostics
Module 11
Troubleshooting, Management, Monitoring, and Diagnostics

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.

4. Learning Objectives Demonstrate proficiency using TCP/IP utilities
Identify the common tools used to troubleshoot a wireless network
Identify single point failures on a WLAN.
Configure SNMP and Syslog logging
Identify basic facts about CiscoWorks WLSE and ACAT tool.

48. WLSE Value Propositions
Reduces WLAN total cost of ownership by saving time and resources in configuring a large number of access points and bridges
Minimizes wireless LAN security vulnerabilities by providing alerts for misconfigured access points and bridges

49. WLSE Value Propositions (cont.)
Improves wireless LAN uptime by proactively monitoring wireless LAN infrastructure and “LEAP authentication server”
Helps in wireless LAN capacity planning by identifying the most utilized access points
Accelerates client problem troubleshooting by generating client association reports
Proactive monitoring of access points, LEAP authentication servers, and switches connected to access points is critical to improving and ensuring WLAN uptime. Faults generated by the WLSE when performance degrades and when devices become overloaded allow network engineers to proactively solve potential problems with the WLAN before end-users’ experience becomes unbearable.
The WLSE identifies the most utilized access points in a group in terms of throughput and client associations. Network administrators can use these data for capacity planning, to decide where performance is adequate and where it is inadequate and to prove return on investment for current WLAN deployment and to justify further investment.
Network administrators need tools to accelerate client problem troubleshooting and the WLSE provides these tools. Client problem troubleshooting is accelerated for WLSE users with current and historical client association reports.
