配置EAP連結與技經評估組
簡介
本文檔介紹如何配置可擴展身份驗證協定(EAP)連結的ISE和Windows請求方。
必要條件
需求
思科建議您瞭解以下主題：
-
ISE
-
Windows Supplicant客戶端配置
採用元件
本文中的資訊係根據以下軟體和硬體版本：
- Cisco ISE版本3.0
- Windows 10版本2004
- 基於協定隧道的可擴展身份驗證協定(TEAP)知識
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
背景資訊
TEAP是一種基於隧道的可擴展身份驗證協定方法，它建立安全隧道並在該安全隧道的保護下執行其他EAP方法。
TEAP身份驗證在初始EAP身份請求/響應交換後分兩個階段進行。在第一階段，TEAP使用TLS握手來提供經過驗證的金鑰交換並建立受保護的隧道。隧道建立後，第二階段開始於對等方和伺服器進行進一步對話以建立所需的身份驗證和授權策略。
Cisco ISE 2.7及更高版本支援TEAP協定。型別長度值(TLV)對象在隧道內用於在EAP對等體和EAP伺服器之間傳輸身份驗證相關資料。Microsoft在2020年5月發佈的Windows 10 2004版中引入了TEAP支援。
EAP連結允許在一個EAP/Radius會話內進行使用者和電腦身份驗證，而不是兩個單獨的會話。以前，要實現此目的，您必須具有Cisco AnyConnect NAM模組並在Windows請求方上使用EAP-FAST，因為本地Windows請求方不支援此功能。現在，您可以使用Windows原生Supplicant客戶端使用TEAP通過ISE 2.7執行EAP連結。
設定
Cisco ISE配置
1.您必須編輯「允許的協定」以啟用TEAP和EAP連結。
2.導航至ISE > Policy > Policy Elements > Results > Authentication > Allowed Protocols > Add New. Check the TEAP and EAP chaining覈取方塊。
3.建立證書配置檔案並將其新增到身份源序列。
4.導航到ISE > Administration > Identities > Identity Source Sequence，然後選擇Certificate Authentication Profile。
5.您必須在身份驗證策略中呼叫此序列。
6.導航到ISE > Policy > Policy Sets. Choose the Policy Set for Dot1x > Authentication Policy，然後選擇Identity Source Sequences created in Step 3。
7.現在，您必須修改Dot1x Policy 集下的Authorization Policy。
8.導航到ISE > Policy > Policy . Sets為Dot1x > Authentication Policy選擇Policy Set。您必須建立兩個規則。第一條 規則檢查電腦是否已驗證，但使用者未驗證。第二個規則驗證使用者和電腦現在均通過身份驗證。
9.從ISE伺服器端完成配置。
Windows原生Supplicant客戶端配置
配置本文檔中的有線身份驗證設定。
1.導航到控制面板>網路和共用中心>更改介面卡設定，然後按一下右鍵LAN連線>屬性。點選Authentication選項卡。
2.按一下Authentication下拉選單並選擇Microsoft EAP-TEAP。
3.按一下 Settings 按鈕。
- 保持啟用匿名身份隱私(Keep Enable Identity Privacy ) 作為身份。
- 在受信任的根證書頒發機構下，在根CA伺服器旁邊放置一個複選標籤，該複選標籤用於對ISE PSN上的EAP身份驗證證書進行簽名。
4.在Client Authentication下，選擇用於Microsoft身份驗證的EAP方法：其他證書的智慧卡。
5.對於每個EAP方法下拉選單，按一下Configure按鈕並根據要求進行修改，然後按一下OK。
6.按一下「其他設定」 按鈕。
- 啟用Specify authentication mode。
- 將下拉選單設定為適當的設定。
- 選擇「User or computer authentication（使用者或電腦身份驗證）」 ，使兩者均經過身份驗證，然後單擊「OK」。
驗證
您可以重新啟動Windows 10電腦，也可以註銷然後登入。顯示Windows登入螢幕時，會觸發電腦身份驗證。
在即時日誌中，可以在身份欄位中看到匿名、主機/管理員（此示例顯示電腦名稱）。您會看到anonymous，因為您在上方為身份隱私配置了請求方。
當您使用憑證登入PC時，您會看到即時日誌為Administrator@example.local，主機/管理員。這是EAP連結，使用者和電腦身份驗證都發生在一個EAP會話中。
詳細的身份驗證報告
在Live Log Details中，電腦身份驗證只顯示一個條目，但是，鏈結使用者和電腦身份驗證顯示兩個條NACRadiusUsername目（一個使用者條目，一個電腦條目）。 此外，您在Authentication Details部分下看到，TEAP(EAP-TLS)已用於身份驗證協定。如果將MSCHAPv2用於電腦和使用者身份驗證，則身份驗證協定顯示TEAP(Microsoft:安全密碼(EAP-MSCHAP v2.)
機器驗證
使用者和電腦身份驗證
疑難排解
必須在ISE上啟用這些調試：
- 運行時AAA
- nsf
- nsf-session
Active Directory（在ISE和AD之間進行故障排除）
在Windows上，可以檢查事件檢視器日誌。
