Solved: Re: Cannot see the APs in WLC 2500

Tazio4436 · ‎12-18-2021

Hi All,

Couple of days ago I asked for help to to default some old APs and to make them resister with my working WLC. I got help and tried it and it worked fine and today I am all panicked now as I came on site to do the deployment but non of the defaulted APs are not working. I tried all the other steps I di coupe of days ago but still no luck.

I cannot see the Aps on WLC

A quick help will be much appreciated to save my day

Please see sh ip int brief and log display from AP

I believe this could be the issue

License Eula: Not Accepted

If you go to "Management > Licenses " add AP count & hit "Set count" button.

Then it should prompt you to accept EULA agreement. Then test it again & see

Do you also have 2nd WLC in network ? if yes then check if you have configured as HA ?

Follow this to configure HA N+1:

https://rscciew.wordpress.com/2014/06/07/n1-high-availability-configuration-on-cisco-2504wlc/

set WLC1 (with 25 AP license) to primary and set other wlc(12 AP license) to secondary and then you can use 75 AP license on secondary one.

- No , that is a secondary message, in the end the controller gets confused. The first line is most important, as stated check if a reboot can help.

Yes I have it and primary WLC has 25 AP license. Secondary WLC only has 12 AP license.
