well my problem start when i try to add a WLC version 4.2.130 with WCS version 18.104.22.168. am search in forum and release note and nowhere i can find the explict text say "WLC 4.2.130 is compatibility with WCS 22.214.171.124" this is one.
Well i have two error, one in wcs it say "object no found device" and in WLC say "snmp authentication failure ip x.x.x.x (the ip of wcs).
am try to do a telnet with port 161 from wcs to wlc and i have't reply.
The wlc and wcs is directly conected throught a core 4600.
Re: Problem when add WLC 4.2.130 witch WCS 126.96.36.199
WCS needs to be a higher version for this to work. SNMP is used between the WCS and WLC and the situation you have now is that WCS is not getting the proper answers when it talks to the controller.
My suggestion at this point would be to upgrade WCS to 188.8.131.52 and all should be good. Check the release notes for WCS 184.108.40.206 for compatible WLC and Location Appliance versions but 220.127.116.11 is fine for now.
