简介

Cisco网络服务访问登记(AR) 3.0支持小型可扩展认证协议(LEAP) (Cisco无线)。本文显示如何配置无线Aironet客户端工具和Cisco Aironet 340， 350或者1200系列接入点(AP) LEAP认证的对Cisco AR。

先决条件

要求

本文档没有任何特定的前提条件。

使用的组件

本文档中的信息基于以下软件和硬件版本：

  • Cisco Aironet® 340， 350或者1200系列接入点

配置 EAP-Cisco 无线 (CISCO LEAP)

此部分包括Cisco LEAP基本配置在思科AR服务器、AP和多种客户端的。

逐步指导

遵从这些说明配置LEAP ：

  1. 更换思科AR服务器的端口。

    AP发送关于用户数据报协议(UDP)端口1812 (验证)和1813的RADIUS信息(核算)。默认情况下因为思科AR在UDP端口1645和1646侦听，您在UDP端口1812和1813必须配置思科AR侦听。

    1. 发出cd /radius/advanced/ports命令。

    2. 发出add 1812命令添加端口1812。

    3. 如果计划执行核算，发出add 1813命令添加端口1813。

    保存配置，然后重新启动服务。

  2. 添加对思科AR服务器的AP，发出这些命令：

    • cd /Radius/Clients

    • 添加ap350-1

    • cd ap350-1

    • 设置IP地址171.69.89.1

    • 设置sharedsecret cisco

  3. 要配置有线等效保密(WEP)密钥会话超时，请发出这些命令：

    注意： 802.1x指定重新验证选项。Cisco LEAP算法使用此选项超时用户的当前WEP会话密钥和发出一新的WEP会话密钥。

    • cd /Radius/Profiles

    • 添加ap-profile

    • cd ap-profile

    • cd属性

    • 设置session-timeout 600

  4. 要创建使用配置文件的用户组在步骤3添加了，发出这些命令：

    • cd /Radius/Usergroups

    • 添加ap-group

    • cd ap-group

    • 设置baseprofile ap-profile

    用户在此用户组中继承配置文件和反之接收会话超时。

  5. 要创建用户列表和添加的用户用户对在步骤定义的用户组4，发出这些命令：

    • cd /Radius/Userlists

    • 添加ap用户

    • cd ap用户

    • 添加user1

    • cd user1

    • set password思科

    • 集合组ap-group

  6. 要创建本地认证和授权服务使用UserService “ap-userservice”和设置服务类型为“eap-leap”，请发出这些命令：

    • cd /Radius/Services

    • 添加ap-localservice

    • cd ap-localservice

    • set type eap-leap

    • 设置UserService ap-userservice

  7. 要创建用户服务“ap-userservice”使用定义的用户列表在步骤5，请发出这些命令：

    • cd /Radius/Services

    • 添加ap-userservice

    • cd ap-localservice

    • set type本地

    • 设置userlist ap-users

  8. 要设置默认验证和授权请服务思科AR使用对定义的服务在步骤6，发出这些命令：

    • cd /radius

    • 设置defaultauthenticationservice ap-localservice

    • 设置defaultauthorizationservice ap-localservice

  9. 要保存和重新加载配置，请发出这些命令：

    • 保存

    • 重新加载

在 AP上 启用 EAP-Cisco (CISCO LEAP)

逐步指导

遵从这些步骤启用在AP的Cisco LEAP ：

  1. 浏览对AP。

  2. 从Summary Status页，请点击设置。

  3. 在服务菜单，请点击Security > Authentication服务器。

  4. 选择802.1x版本运行在802.1x协议版本下拉菜单的此AP。

  5. 配置思科AR的IP地址在服务器名/IP文本框的。

  6. 验证下拉菜单设置为RADIUS的服务器类型。

  7. 更换波尔特文本框对1812。这是使用的正确IP端口号与思科AR。

  8. 配置有在思科AR使用的值的共享秘密文本框。

  9. 选择EAP Authentication复选框。

  10. 修改超时文本框，如果如此希望。这是认证请求的超时值思科AR的。

  11. 点击OK键返回到Security Setup屏幕。

    如果也执行认为的RADIUS，请验证核算设置页的端口与在思科AR配置的端口一致(1813的集)。

  12. 单击 Radio Data Encryption (WEP)。

  13. 通过键入在WEP密钥1文本框的一40或128比特的关键值配置广播WEP密钥。

  14. 选择认证类型使用。确保，最少， Network-EAP复选框选择。

  15. 验证下拉菜单设置为可选或全部加密的Use of Data Encryption。可选允许使用非WEP和WEP客户端同样AP的。注意这是不安全操作模式。请使用完全加密，当可能。

  16. 点击OK键完成。

配置ACU 6.00

逐步指导

遵从这些步骤配置ACU ：

  1. 打开 ACU。

  2. 点击工具栏的配置文件管理器。

  3. 单击添加创建新配置文件。

  4. 输入在文本框的配置文件名称，然后点击OK键。

  5. 输入在SSID1文本框的适当的服务集标识(SSID)。

  6. 点击网络安全。

  7. 选择从网络安全类型下拉菜单的LEAP。

  8. 单击 Configure。

  9. 配置密码设置当必要时。

  10. 单击 Ok。

  11. 点击OK键在Network Security屏幕的。

从 Cisco AR 跟踪

发出trace /r 5得到在思科AR的trace输出。如果需要AP调试，您能连接到AP通过Telnet和发出eap_diag1_on和eap_diag2_on命令。
