%CAPWAP-3-ERRORLOG: CAPWAP SM handler: Failed to process message type 2 state 2.
%CAPWAP-3-ERRORLOG: Failed to handle capwap control message from controller

该信息表明AP无法被当前控制器版本所支持，WLC拒绝了AP的discovery 请求。
但是大家查无线软件兼容性list，发现1042在7.0.98.0就已经支持了，为什么现在版本高于这个还是无法加入。
兼容性list 在此：http://www.cisco.com/c/en/us/td/ ... ibility-matrix.html
其实这个AP是AIR-LAP1042N-C-K9H，而不是AIR-LAP1042N-C-K9 只有一个H 之差。

这个AP是新的AP，使用的OS 跟 702是一样的。 show version显示是ap1g1 ，
而老的1042 show version是C1140。
所以这个AP要按照702的兼容性去对待，要使用7.6的OS，目前cisco download里有下载7.6.130.0
下面是AP的show version信息：

最近有人发现这个AP无法加入WLC，AP上能看到如下报错信息
