Wireless Troubleshooting Tools
In order to help people in the field, doing Wireless networks troubleshooting and RF analysis, the WNG Escalation, TAC and Development teams have made available several tools to facilitate some of the most common tasks.
Wireless Config Analyzer Express - WCAE
How to use unsigned builds in Mac OS (Ventura, etc)
Until file gets signed version, you may need to explicitly change permissions to allow application execution. For example, If the zip file was expanded in Downloads folder, you will need to open terminal, go to the directory, and reset permissions there:
cd Downloads
xattr -dr com.apple.quarantine ./wcae.app/
This is only needed once, then application should work.
WCAE GUI
Version 0.9 - October 2024 New! Radius best practices, AP flash monitoring, Radio failures, and several other new checks
Mini Desktop (AireOS and 9800)
Version 0.18 - December 2023
Next generation, multi platform Wireless Analyzer tool, including checks from WLCCA, and several new additions
WLAN Poller
Bulk data collection script system, focused on capturing debugging data, flash checks and DFS stats collections for large groups of Access points
9800 Guestshell scripts
Automate complex data collection and troubleshooting, using the advanced programmable feature of the 9800
WiFi Hawk
New version 0.18 - February - 2023
Over the air captures (OTA) can be sometimes very difficult to analyze, with multiple devices interacting to each other, or critical events triggered by a single frame, hidden among thousands of others. This tool is focused on making it easy to process and isolate device behavior, speeding up wireless troubleshooting
Wireless Lan Config Analyzer - WLCCA
-
It is desktop Windows application, supporting only AireOS controllers Provides around 300+ configuration checks, RF analysis and RF Health evaluation This tool support is limited, please use WCAE for new checks/features
9800 Traces to ELK - Github
Example application to automatically retrieve traces from the new Cisco 9800 Wireless controller and display different information on a Kibana dashboard.
9800 Telemetry Pipeline - Github
Real time visualisation and analysis of C9800 wireless controller telemetry data streaming. It uses dial-out telemetry to push a periodic stream of wireless operational data to an open source collector
Wireless Debug Analyzer
This tool aims to provide logical analysis based on log sequence to match against known issues. For AireOS the tool can also parse through the output of "debug client
9800 Advanced Debug Insights is a new insight dashboard to analyze RA traces quickly. It provides a quick summary of client roam stats, onboard time, delete reasons, and the number of client sessions per WLAN(Success & Failures). It also provides a high-level table view of all client connection attempts with a start, the end time stamp for each session, delete reason, Auth method, and AP name, and further detailed view can also be seen with all the transactions between clients, AP, WLC in a sequence diagram.
Standard Wireless debugs produce tons of lines of information which takes a long time to collect, analyze and eventually determine the cause.
Approximately 35% of SRs (Volume) is to troubleshoot client issues (drops, disconnects, roam failures). To analyze them manually is time and bandwidth-consuming. Manual analysis is prone to errors. The dashboard gives a holistic & detailed view.
WLC Config Converter BETA
Helps on migrating wireless controllers to or from across any of these platforms: 2500/5500/7500/8500/WISM2/3650/3850/4500 S8E/5760/Catalyst 9800 controllers
