New experimental troubleshooting tool: “RF Health”
This is a modification of the RF index to change the format to a 0 to 100 metric, the higher the better, for a easier to use experience
it should work properly to isolate what areas/Aps of the deployment are having a bad RF state, affecting clients.
RF Health will try to calculate different metrics applicable to RF quality on the AP, and convert to a single 100 based scale. It takes into consideration things like low SNR client count, co-channel interference, channel utilization for nearby Aps, noise, etc.
It currently supports 20/40 channel width, and handles properly bonding scenarios.
You can open “RF problem finder” to get details on the metric per type, per AP, for in depth analysis
Please provide your feedback on the metric, for additional improvements, change on default values, etc.

Should "WLC" acronym be defined in the first line?
Nice tool.
When will it be possible to load and analyze WLC 6.x software versions?
Hi
I will be adding 6.0 specific checks to version 2.0 in the short future... please stay tunned
You can process 6.0 today, just no special checks yet.
Javier, when I try to install it, it says that it's already installed, do you have any thoughts on this?
Hi Kayle
I would need more details.
Could you send us your install logs, which version are you installing, and on which operating system (version, language)? Please use this address to report any issues with the application: wlc-conf-app-dev@cisco.com
Thanks!
Hi
Well, not really... :-)
WLC is Wireless Lan Controller, acronym used extensively across most Cisco public documentation.
Regards
Cool!
How do you use the program to compare 2 or more wireless controller configs
Hi Joseph
Two ways of doing it:
procedure 1
1. Opening different configuration sets. click on the first icon in the tool bar, load a config file
2. Click again on same icon, it should create a new window, open the second WLC
3. You now have 2 configs showing up in the screen, you can now compare manually
procedure 2
1. put both config files on same text file
2. load them on the application (it supports up to 24 WLCs per config set)
3. It will do automatic comparision for mobility, wlan, interface, etc
if you load 2 times the same config, you will get several errors on duplicate addreses, system name and/or AP names, but sometimes people do it, so compare wlan configuration over time
Regards!
Javier,
Thanks for responding to my email last night about the easiest way to get started. I was able to use this tool to identify several weak areas in my configuration today, and thanks to the tips the utility provided, my wireless network (voice and data) are running better than ever! I noticed dramatically better coverage in a few areas where coverage had previously been low due to some radio misconfigurations, and my call quality while roaming is much improved as well since I was able to identify a few settings that were negatively impacting roaming abilities.
Thanks for this utility, and all your efforts on this project!
For some reason I'm not able to scroll the AP list in the TPC Prediction dialog. Both scroll bars are disabled. At first I thought it might be a Win7 thing but I've had the same issue under XP. Am I doing something wrong?
Hi
TPC predictor was a "experimental" test I did time ago for a case. It needs serious re-work, to match the new TPC algorithms in 7.0 and 6.0 latest code. The issue you mention, that the tabs and grid scroll bars are not responsive is fixed on next build (it was minor detail) , but I will disable the feature altogether until I have time for 2.3 or 2.4 is out, when I plan to introduce several RF analysis ideas I have around.
the current output is not entirely correct. Anyway, if you have ideas or feedback for this feature, feel free to contact me to discuss inclusion on next version.
Regards
Javier,
I cobbled together an expect script to pull the run-config from a controller and all looks well on the output, but config analyzer compains "controller information not found in selected file" The scripts are at https://supportforums.cisco.com/message/3437283#3437283
I can modify them as needed, but I am not sure where the analyzer is looking for that info.
Thanks,
Eric Garnel
Hi Eric
Can you send me the resulting output file from your script?
I can have a quick look and see what is missing.
Normally, that message means that WLCCA did not see the "System Inventory" line on the beginning of the file
(that is used as marker for start or new config)
Regards
Javier,
I have cleaned up the scripts, and the analyzer recognizes the output, but kicks out parsing errors.
the updated info is at: https://supportforums.cisco.com/message/3438433#3438433
the raw output from the controller is 1 very long line with ^M^Ms sprinkled throughout. In order to pull out the expect user pass & ip info, the file needs to be massaged
here is a sample of the output:
