Bruno,
there is an offline version of this tool. It’s called WLCCA (Wireless LAN Controller Config Analyzer)
This web tool is the “Express” version.

Curious on where the export feature stands. Would love to see json as an option.
or, api access so we can get the results directly.

Agreed on the +1. I'm not finding where to prepend that in the SMS settings, since the TO is set in the $message$.

2800 sqft means you don’t get channel reuse. For starters, you probably need to turn off at least one of the 2.4GHz radios. You are just adding overhead that is reducing overall capacity. Without knowing what the rest of the environment looks like, more 2.4Ghz may need to be disabled. With only 3 available channels, 4 APs in a room is not helping. Adding more radios will make things worse. I would also question what your channel utilization looks like. My guess is they added two APs and they ended up on the same channels and ultimately reduced overall capacity. A restart of DCA might help them pick other channels. I would disable one of the 2.4Ghz radios before doing that. Then very careful watch channel utilization while the environment is busy. If you have Prime Infrastructure the radio utilization report may prove insightful. ISE is probably not the cause, but I can’t rule that out. If there is excessive authentication traffic, that could cause higher utilization. Sent from my iPhone

FYI, this is not necessary. They will use the PNP option every boot, so after they upgrade they will autonatically check PNP post image upgrade.

i just did this with a staging controller for 2802 APs, because they don't do PNP on their 8.2 code. DHCP option for staging controller, DNS for PNP. first boot they join the staging controller, upgrade to 8.3, then I have a script run to clear config on the AP. Then they boot, PNP and get their real config. the flex group is harder, as the config clearing script would have to check that they were not in a flex group. Totally doable.

Hmm, just tested in 2.1 P2 and no dice. Anyone know of a way to debug the SMS component to see what's failing?

My question is why can't you use radius from wlc-A to ISE03? You poke holes to allow ISE03 to talk to the admin/mnt nodes. So why not to WLC-A for radius?
For another test, try letting the wlc use ise03 as the radius server and see if that also works.
What version of ISE are you running? I'm load-balancing PSNs in 2.1 and haven't run into that error. Are these in different node groups?

What I'm saying is that you can interoperable the two and allow the capwap through the core switch to the airespace controller. IRCM works across both platforms, so there is a valid mixed environment model.

In 3.6 and 3.7 code, you can prevent a switch from intercepting capwap by putting the AP on a VLAN other than the VLAN defined for wireless management. We do this today to flip APs from 3850 MA/MC to a central 5508. So this limitation that has you so concerned is not a valid limitation anymore.

So, i was able to get mine imported. I ran "/opt/cmx/bin/cmxconfig import prime" and it was able to import. Following the cmxctl method did not work. This also imported my controllers.

One of the things that came out of our weekly engineering meeting was that we are seeing huge lead times when it comes to license rehosting. Are others seeing 2+ weeks to rehost licenses? I haven't submitted many licensing requests lately, but wanted to see if this has become the norm. We also are hearing rumors that all licensing requests are going back to the BU for verification. are other seeing this? Cisco is something up? I'm getting some feedback from customers that things on this front are not good.
