Dear Team, i have a Controller based Installation with 802.1x Auth via ACSSE and AD. The Controllers running 220.127.116.11. 2 ACSSE are configured. Since a few Days we see Problems with Client Authentication. The WLC Log shows, that the WLAN toggles between the 2 Radius Servers:
84 Tue Dec 9 09:29:19 2008 RADIUS server xx.xx.xx.xx:1812 activated on WLAN 2
85 Tue Dec 9 09:29:19 2008 RADIUS server xx.xx.xx.yy:1812 deactivated on WLAN 2
86 Tue Dec 9 09:29:19 2008 RADIUS server xx.xx.xx.yy:1812 failed to respond to request (ID 148) for client <Client-MAC> / user 'unknown'
Does anyone know, under which Conditions, Timeout etc the WLAN changes the Radius Server? Since we dont run 5.x , we cant use the dedicated Radius Fallback Feature. Has anyone seen this Problem? Regards, Michael
