我对思科无线网络还不太熟悉，我正尝试将 AIRCAP 3602i 接入点连接到 2504 无线控制器。
我首先配置了无线控制器，其管理 IP 为 192.168.2.1/24。此设备未连接到任何其他设备（甚至没有连接到互联网连接的上行链路）。
然后，我将 AP 连接到无线控制器，然后通过控制台电缆连接到 AP，但是我不断收到以下错误：

在稍后的阶段，上述错误停止，并出现类似于以下的错误：
Not sending discovery request AP does not have an Ip !!
我找不到任何关于如何将此设备重置为出厂设置的指示。当我将 AP 连接到无线控制器时，控制器无法检测到它。
有人能指导我如何将 AP 连接到无线控制器或如何将其重置为出厂默认设置吗？
答案1
您好，问题是 AP 无法找到/看到控制器。
“无法解析 CISCO-CAPWAP-CONTROLLER”
最可能的原因是您使用的 DHCP 池缺少选项 43 = IP。这会告诉 AP WLC 的 IP 地址是什么。
IE
ip dhcp pool VLAN30
import all
network 10.0.30.0 255.255.255.252
default-router 10.0.30.1
option 60 ascii "Cisco AP c1140"
option 43 hex 0a00.6304 // points to 10.0.99.4 WLC
lease 0 4
