I am trying to add a controller in a lab environment. When I input all the information and press Add, I am getting this error message;
Failed to add device to WCS Reason: SNMP operation to Device failed: Sparse table not supported
Can someone help?
Yes, now that you are at WLC 6.0.182, you need WCS 188.8.131.52, that should fix the error you posted.
If you have other issues after you upgrade WCS, let me know.
The upgrade of WCS is very simple and should take 15 minutes at the most.
Just download the newer version, make a backup of the db just in case and proceed with the install.
Most likely this is due to use of a newer version of the WLC (controller) than the WCS.
Make sure you are running a similar or newer version of WCS that supports the WLC.
Check the release notes for WCS to see in what version your WLC is supported:
