I am installing a WLC and LWAPPs to replace heavyweight Cisco 1121 AP's. I have deployed the WLC and LWAPP's in the same subnet as the Original 1121's. I have replicated the 1121 settings on the controller.
The scanners associate with the SSID and pass authentication on the ACS server. However the linktest fails from the WLC the scanners can't ping theit servers either. However the WLC can ping the scanner's server.
It works fine when I bring the scanners back to a location with the heavyweight 1121's.
Just out of curiousity, are you using Symbol / Motorola scanners? There was an EAP setting on the WLC that needed to be set in order to get my handhelds to play nice with 802.1X. Check to see if this setting is in place on the WLC...
key index = 3, not 0
To check, run this...
show advanced eap
Check the key index value. If it is zero, please try setting it to three.
config advanced eap key-index 3
Also, if this is indeed Motorola equipment, I recommend that you have the latest OS update (wireless Fusion drivers) installed...
