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.
Version v1.0 - January 2025
New!
Large collection of improvements and fixes for this release, including several last case scenarios, and a new export function, to generate a custom JSON file, you can load later, and save all the parsing time. This is especially important when dealing with very large files
New packaging for windows, this seems to reduce the false positives, plus it also has faster startup time, and improved processing time.
No installation required, expand the zip and execute wcae.exe
Bulk data collection script system, focused on capturing debugging data, flash checks and DFS stats collections for large groups of Access points
Automate complex data collection and troubleshooting, using the advanced programmable feature of the 9800
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
Download V4.4.15
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
Example application to automatically retrieve traces from the new Cisco 9800 Wireless controller and display different information on a Kibana dashboard.
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
Documentation and Details
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 ..." as well as some portions of "debug aaa/webauth/mdns". For Catalyst 9800 WLC, the tool can parse through always-on traces and radio-active trace logs generated from WLC. For 9800 RA traces, there is an advanced insights dashboard that is newly added.
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.
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
