非歧视性语言

此产品的文档集力求使用非歧视性语言。在本文档集中，非歧视性语言是指不隐含针对年龄、残障、性别、种族身份、族群身份、性取向、社会经济地位和交叉性的歧视的语言。由于产品软件的用户界面中使用的硬编码语言、基于 RFP 文档使用的语言或引用的第三方产品使用的语言，文档中可能无法确保完全使用非歧视性语言。深入了解思科如何使用包容性语言。

关于此翻译

思科采用人工翻译与机器翻译相结合的方式将此文档翻译成不同语言，希望全球的用户都能通过各自的语言得到支持性的内容。请注意：即使是最好的机器翻译，其准确度也不及专业翻译人员的水平。 Cisco Systems, Inc. 对于翻译的准确性不承担任何责任，并建议您总是参考英文原始文档（已提供链接）。

简介

本文档介绍如何在新的移动部署设置中为无线客户端访客锚点配置5508/5760系列无线LAN控制器(WLC)和Catalyst 3850系列交换机，其中5508系列WLC充当移动锚点，而Catalyst 3850系列交换机充当客户端的移动外部控制器。此外，Catalyst 3850系列交换机作为移动代理连接到5760系列WLC，后者作为移动控制器，Catalyst 3850系列交换机从中获取接入点(AP)许可证。

先决条件

要求

Cisco 建议您在尝试进行此配置之前了解下列主题：

融合接^入5760和3650系列WLC和Catalyst 3850系列交换机的Cisco IOS® GUI或CLI
5508系列WLC的GUI和CLI访问
服务集标识符(SSID)配置
Web 身份验证

使用的组件

本文档中的信息基于以下软件和硬件版本：

Cisco 5760版本3.3.3（下一代配线间[NGWC]）
Catalyst 3850 系列交换机
思科5508系列WLC版本7.6.120
思科3602系列轻量AP
Cisco Catalyst 3560 系列交换机

本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。

配置

注意：要获取有关本部分中所使用命令的更多信息，可使用命令查找工具（仅限已注册客户）。

网络图

5508系列WLC充当锚点控制器，Catalyst 3850系列交换机充当外部控制器和从移动控制器5760获取许可证的移动代理。

注：在网络图中，5508系列WLC充当锚点控制器，5760系列WLC充当移动控制器，Catalyst 3850系列交换机充当移动代理和外部WLC。在任何时间点，Catalyst 3850系列交换机的锚点控制器是5760系列WLC或5508系列WLC。两个锚点不能同时为锚点，因为双锚点不起作用。

配置

配置包括三个部分：

第1部分 — 5508锚点WLC上的配置

第2部分 — 5508/5760系列WLC和Catalyst 3850系列交换机之间的融合接入移动配置

第3部分 — 外部Catalyst 3850系列交换机的配置

第1部分 — 5508锚点WLC上的配置

在5508系列WLC上，将鼠标悬停在WLAN > New上，以便创建新的无线LAN(WLAN)。
将鼠标悬停在WLAN > WLAN Edit > Security > Layer 3 enabled Web-authentication上，以配置第3层安全。
在WLAN移动锚点配置窗口下将锚点地址设为local，以便将5508系列WLC添加为锚点。
将鼠标悬停在Security > Webauth > Webauth page上，以配置用于客户端身份验证的Webauth页。

在本示例中，选择WLC Internal Webauth页面：
创建本地网络用户。在Webauth页面上出现提示时，用户将使用此用户名/密码对。

第2部分 — 5508/5760系列WLC和Catalyst 3850系列交换机之间的融合接入移动配置

在5508系列WLC上，添加5760系列WLC作为移动对等体。
在5760系列WLC上，作为移动控制器，添加5508系列WLC作为移动对等体。
此步骤非常重要！将Catalyst 3850系列交换机作为5760系列WLC上的移动代理添加到Mobility Management下的Switch Peer Group选项卡下。
在Catalyst 3850系列交换机上，添加5760系列WLC作为移动控制器。执行此操作后，Catalyst 3850系列交换机将从移动控制器5760获取AP无法使用的许可证。

第3部分：外部Catalyst 3850系列交换机的配置

将鼠标悬停在GUI > Configuration > Wireless > WLAN > New上，以便在Catalyst 3850系列交换机上配置确切的SSID/WLAN。
将鼠标悬停在WLAN > WLAN Edit > Security > Layer 3 enabled Web-authentication上，以配置第3层安全。
将5508系列WLC IP地址添加为WLAN移动锚点配置下的锚点

验证

使用本部分可确认配置能否正常运行。

将客户端连接到WLAN思科统一无线网络(CUWN)。工作流程如下：

客户端收到IP地址。
客户端打开浏览器并访问任何网站。
客户端发送的第一个TCP数据包被WLC拦截，WLC拦截并发送Webauth页面。
如果DNS配置正确，客户端将获得Webauth页面。
客户端必须提供用户名/密码才能进行身份验证。
身份验证成功后，客户端将重定向到原始访问页面。
在客户端提供正确的凭证后，客户端将传递身份验证。

故障排除

要排除配置故障，请在5508系列WLC上输入以下调试，它充当访客锚点：

Debug Client 
       
       
Debug web-auth redirect enable mac

示例如下：

Debug Client 00:17:7C:2F:B6:9A
Debug web-auth redirect enable mac 00:17:7C:2F:B6:9A

show debug 

MAC Addr 1.................................. 00:17:7C:2F:B6:9A

  pem state enabled.
  CCKM client debug enabled.
  webauth redirect enabled.
