Cisco AIR-AP2802I-H-K9 加不进WLC2504，急~~

prince_901115

拓扑大概为以下图片，但先不理上网网关这块。DHCP在WLC上，AP从WLC获取DHCP，能ping通WLC但就是加不进去，
WLC版本也刷过，目前为：Software Version：8.2.141.0  Field Recovery Image Version：7.6.101.1。
AP为ap3g3。

二层交换机配置：VLAN258为management，VLAN196为AP的网段。

show ap join stats detailed中有如下报错：

而且AP获取到ip后能ping通WLC 172.18.96.241，但一直弹出以下信息：

这个问题缠了我一个多月了，跪求大神出手相救，万分感激，好人一身平安！！！

首先你先检查wlc 的license 是否激活 看起来是AP 不知道wlc 的地址 试试改成路由器当Dhcp sever, 然后在option 43 上指定wlc 的IP。 另外你的switch access port. 和Trunk port 的设置建议回去复习重设一遍

pt能模拟wlc嘛

能把WLC的日志放这吗？
