I have an existing setup with all 6 wlc's at the same firmware level :
1 anchor controller : V4.2.130
5 internal controllers : V4.2.130
We recently installed a 7th new type WLC2112 which came with firmware version 5.2.193
There are 2 SSID's which are anchored between internal and anchor controllers:
SSID "Guests" uses L3 Security Web auth : no problem
SSID "Maximo" uses L2 Security WPA+WPA2 - PSK : problem on new controller
When the AP is joined to the new wlc2112(V5.2.193) trying to connect to SSID "Maximo" fails : Client Authentication fails .
When the same AP is joined to an old wlc (V4.2.130) connecting to SSID "Maximo" is OK
The other anchored SSID "Guests" is working fine on all internal wlc's .
I checked the Cisco wlc firmware version matrix for internal--anchor controllers and the combination of wlc firmware versions we have is OK .
Any idea's ?
