RE: [WIRELESS-LAN] Anyone using 5.0 Cisco WiSM/WLC code?
Here in Melbourne, We have 5.0.148 getting ready to go into production but there is tension about bug CSCsm98250 (5.0 Webauth stops working under load). We have not run into this yet but we also have no load on (yet). Has any experienced this? Does the controller stop or just management?
