本節介紹Cisco AR伺服器、AP以及各種客戶端上Cisco LEAP的基本配置。
按照以下說明配置LEAP:
更改Cisco AR伺服器上的埠。
AP在使用者資料包通訊協定(UDP)連線埠1812(驗證)和1813(計量)上傳送RADIUS資訊。 由於預設情況下Cisco AR在UDP埠1645和1646上偵聽,因此您必須將Cisco AR配置為在UDP埠1812和1813上偵聽。
發出cd /radius/advanced/ports命令。
發出add 1812命令以新增埠1812。
如果您計畫執行記帳,請發出add 1813命令以新增埠1813。
儲存配置,然後重新啟動服務。
要將AP新增到Cisco AR伺服器,請發出以下命令:
cd /Radius/客戶端
新增ap350-1
cd ap350-1
set ipaddress 171.69.89.1
set sharedsecret cisco
要配置有線等效保密(WEP)金鑰會話超時,請發出以下命令:
注意:802.1x指定重新身份驗證選項。Cisco LEAP演算法利用此選項為使用者終止當前WEP會話金鑰並發出新的WEP會話金鑰。
cd /Radius/Profiles
add ap-profile
cd ap-profile
cd屬性
set session-timeout 600
要建立使用步驟3中新增的配置檔案的使用者組,請發出以下命令:
cd /Radius/Usergroups
add ap-group
cd ap-group
set baseprofile ap-profile
此使用者組中的使用者將繼承配置檔案,並接收會話超時。
要在使用者清單中建立使用者並將使用者新增到步驟4中定義的使用者組,請發出以下命令:
cd /Radius/Userlists
新增ap使用者
cd ap-users
add user1
cd使用者1
set password Cisco
set group ap-group
要建立本地身份驗證和授權服務以使用UserService「ap-userservice」並將服務型別設定為「eap-leap」,請發出以下命令:
cd /Radius/Services
add ap-localservice
cd ap-localservice
set type eap-leap
set UserService ap-userservice
要建立使用者服務「ap-userservice」以使用步驟5中定義的使用者清單,請發出以下命令:
cd /Radius/Services
add ap-userservice
cd ap-localservice
set type local
set userlist ap-users
要將Cisco AR使用的預設身份驗證和授權服務設定為步驟6中定義的服務,請發出以下命令:
cd /radius
set defaultauthenticationservice ap-localservice
set defaultauthorizationservice ap-localservice
若要儲存並重新載入組態,請發出以下命令:
儲存
重新載入
按照以下步驟在AP上啟用Cisco LEAP:
瀏覽至AP。
在「摘要狀態」頁中,按一下設定。
在「服務」選單中,按一下安全>身份驗證伺服器。
在802.1x協定版本下拉選單中,選擇要在此無線接入點上運行的802.1x版本。
在Server Name/IP文本框中配置Cisco AR的IP地址。
驗證「Server Type(伺服器型別)」下拉選單是否設定為RADIUS。
將「埠」文本框更改為1812。這是與Cisco AR一起使用的正確IP埠號。
使用Cisco AR上使用的值配置Shared Secret文本框。
選中EAP Authentication覈取方塊。
如果需要,請修改「超時」文本框。這是Cisco AR身份驗證請求的超時值。
按一下OK返回到「Security Setup(安全設定)」螢幕。
如果您也在執行RADIUS記帳,請驗證Accounting Setup頁面上的埠是否與Cisco AR(為1813設定)中配置的埠一致。
按一下「Radio Data Encryption(WEP)」。
通過在WEP金鑰1文本框中鍵入40位或128位金鑰值來配置廣播WEP金鑰。
選擇要使用的身份驗證型別。確保至少選中Network-EAP覈取方塊。
驗證「Use of Data Encryption」下拉選單是否設定為「Optional」或「Full Encryption」。可選:允許在相同的AP上使用非WEP和WEP客戶端。請注意,這是一種不安全的操作模式。儘可能使用完全加密。
按一下OK完成。
按照以下步驟配置ACU:
開啟ACU。
按一下工具欄上的配置檔案管理器。
按一下Add建立新配置檔案。
在文本框中輸入配置檔名稱,然後按一下OK。
在SSID1文本框中輸入相應的服務集識別符號(SSID)。
按一下「Network Security」。
從Network Security Type下拉選單中選擇LEAP。
按一下「Configure」。
根據需要配置密碼設定。
按一下「OK」(確定)。
在Network Security螢幕上按一下OK。
發出trace /r 5以獲取Cisco AR上的跟蹤輸出。如果需要AP調試,可以通過Telnet連線到AP並發出eap_diag1_on和eap_diag2_on命令。
