簡介

本文檔顯示路由器和AAA伺服器透過TACACS+進行點對點協定(PPP)回撥的配置示例。包括兩個使用AAA伺服器或Windows 2000客戶端指定的回撥號碼的示例。

  • 使用本地身份驗證和回撥執行初始測試(刪除aaa new-model命令)。如果回撥不能與本地身份驗證一起使用，則不能與TACACS+一起使用。有關如何使用本地身份驗證的示例，請參閱配置路由器與Windows PC之間的MS回撥。

  • 使用TACACS+執行進一步的PPP身份驗證測試，無需回撥。如果使用者未經回撥就使身份驗證和/或授權失敗，則身份驗證和授權不適用於回撥。

  • 回撥的本地身份驗證和使用TACACS+的PPP身份驗證成功之後，請將路由器上本地使用者的資訊（如回撥撥號字串）增加到伺服器上的使用者配置檔案中。

注意：這些測試中的客戶端是照常為PPP連線設定的Windows 2000 Professional客戶端DUN，其中Microsoft Callback設定為「在伺服器提供撥號時詢問我」。 Cisco IOS®軟體版本11.3.2.T及更高版本支援Microsoft回撥。

使用伺服器指定號碼的PPP回撥

伺服器配置

以下是使用AAA伺服器指定的電話號碼的PPP回撥的AAA伺服器配置。

伺服器設定- Cisco Secure ACS for Windows

  • 要為使用者和組啟用LCP選項，請轉到Interface Configuration螢幕，選擇TACACS+ (Cisco IOS)，並確保為User和Group選中PPP IP和PPP LCP選項。

  • 回撥可在「群組」或「使用者」設定中設定。

    • 配置回叫組：在「組設定」螢幕的「回叫」下，選擇使用Windows資料庫回叫設定（在舊版本的ACS中，此選項稱為「使用Microsoft NT回叫設定」）選項。然後檢查PPP IP和PPP LCP的選項。選擇Callback line並在空白欄位中鍵入84007。

      對於作為組成員的使用者，請轉到User Setup螢幕並在Callback下選擇Use group setting。按一下Submit + Restart。

    • 配置回叫的單個使用者：在「使用者設定」螢幕上的「回叫」下，選擇使用此號碼的回叫，並在空白欄位中鍵入84007。然後檢查PPP IP和PPP LCP的選項。按一下Submit + Restart。

chap= cleartext "chapuser"

}
service = ppp protocol = ip {
}
}

使用使用者指定號碼的PPP回撥

本文檔前面的示例是在預定義號碼（在AAA伺服器中指定）處的回撥。回撥也可以使用回撥號碼在使用者指定的號碼完成，並在AAA伺服器中指定為null。這會導致路由器向使用者請求回撥號碼。初始測試應在指定本地回撥的情況下完成。請參閱接入伺服器和PC之間的非同步PPP回撥示例，並注意將「callback-dialstring」指定為引號(「」)。

這些測試中的客戶端是Windows 2000 Professional客戶端，按常規設定用於PPP連線，Microsoft回撥設定為「在以下號碼後回撥」。

注意：顯示的網路圖和路由器配置適用於此處討論的回撥配置。

伺服器配置

此處顯示了使用使用者指定的電話號碼進行PPP回撥的AAA伺服器配置。

  • 回撥可在「群組」或「使用者」設定中設定。

    • 配置回撥組：在「組設定」螢幕的回撥下，選擇撥號客戶端指定回撥號碼的選項。然後檢查PPP IP和PPP LCP的選項。

      對於作為組成員的使用者，請轉到User Setup螢幕並在Callback下選擇Use group setting。按一下Submit + Restart。

    • 配置回撥的單個使用者：在「使用者設定」螢幕的「回撥」下，選擇「撥號客戶端」指定回撥號碼的選項。然後檢查PPP IP和PPP LCP的選項。按一下Submit + Restart。
