well my problem start when i try to add a WLC version 4.2.130 with WCS version 220.127.116.11. am search in forum and release note and nowhere i can find the explict text say "WLC 4.2.130 is compatibility with WCS 18.104.22.168" 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.
There be in the same vlan and the same subnet.
I have ping between they.
Someone know someting about this problem.
