一个无线网络的烦恼！

前几天，接了个做无线的项目。他们呢， 已经有现有的有线网络，目前还在改造中，需要将无线和有线一起暂时先用着，只需要将无线开通就可以了！他们选的设备是无线控制air-ct2504-k9，无线ap air-lap1041n-e-k9，POE供电交换机为cisco 2960pc-l 。控制器ios版本 7.3.101.0

起初的设想将控制器，ap以及poe全部都放在现有的有线网段，因为对无线还是一知半解，不知道可行不，就开始配置起来，后来发现不行，所有的ap不能关联到控制器上。配置错误

然后做出了第二种方法，将ap，交换机和控制器管理划分在一个vlan中，然后让控制器去关联到有限网络的vlan中，其中配置如下：

（1）poe上的配置：poe\#sh run

end

//配置接口信息

\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*

（2）控制器上配置了management地址，跟poe交换机vlan10在同一网段。测试连通性，都能够通信，此时在web上打开控制器页面后，新建一个接口地址属于有线上网段的地址时候，页面就无响应了。

后来查看pc上的arp表的时候，发现控制器上的mac地址上分配了2个ip地址，

最后的解决方案是从网关上做了一条映射，从外网远程配置的，这个问题还是没能解决！
