We have successfully been managing all our WLC's via WCS. Last week one of the 6500 WiSM Controllers stopped responding to config refreshes from the WCS. When re-freshing the WCS config from the controller got the error message - failed (see logs). Removed controller from WCS and re-added - now get different error - see attachment.
WCS version is 4.2.97
WLC version is 4.2.112
Doco says they are compatible.
WCS is successfully managing other WLC's on the same code.
Can any one help?
