有三台胖AP型号均为AIR-AP1242G-E-K9，控制器为AIR-CT2504-K9， 通过UpgradeTool工具将三台AP升级成瘦AP后只有两台成功加入控制器，在用UpgradeTool工具时提示是升级成功的，而且该瘦AP第一次重启后是加入过控制器的，在从控制器看到的状态是在下载新的IOS（其实每台瘦AP加入控制器前都有这个过程），之后该AP便失去联系，本想大批量远程升级成瘦AP的，现在十分纠结。无奈只能将有问题的AP拆下，通过串口看到出错的日志非常奇怪，且网上也搜索不到有帮助的信息，以下是日志：

没有区别啊！
我也遇到类似的问题，也在解决中，也是1240的AP
优秀技术经理
IOS版本不一样！
思 科 技 术
建议手动关联AP， 不自动发现。
现在的努力 、
是为了实现小时候吹过的牛逼 ！！
可以给AP手动指定一个IP地址
