關於此翻譯

思科已使用電腦和人工技術翻譯本文件，讓全世界的使用者能夠以自己的語言理解支援內容。請注意，即使是最佳機器翻譯，也不如專業譯者翻譯的內容準確。Cisco Systems, Inc. 對這些翻譯的準確度概不負責，並建議一律查看原始英文文件（提供連結）。

簡介

本文中的配置示例說明如何配置主要速率介面(PRI)的數字號碼識別服務(DNIS)支援，以及如何設定數據機池。提供了三種配置：

  1. 資料機池，包含在pool-range中定義的多個資料機。

  2. 使用池範圍內的一個數據機進行數據機池。

  3. 沒有池範圍的數據機池。

必要條件

需求

本文件沒有特定需求。

採用元件

本檔案中的資訊是根據以下軟體和硬體版本。

  • Cisco IOS®軟體版本11.3(1.1)T或更高版本。

  • Telco為DNIS支援調配的PRI。

  • 思科AS5x00系列路由器。

註：在Cisco 3600系列路由器上不能使用數據機池。

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。如果您在即時網路中工作，請確保在使用任何命令之前瞭解其潛在影響。

慣例

如需文件慣例的詳細資訊，請參閱思科技術提示慣例。

背景理論

如果您使用遠端撥入使用者服務(RADIUS)作為驗證通訊協定，則需要知道RADIUS(IETF)計費屬性30（站ID）。

Station-ID允許網路接入伺服器(NAS)傳送使用者作為接入請求資料包的一部分呼叫的號碼（使用DNIS或類似技術）。 當與PRI一起使用時，Cisco AS5x00上的ISDN和數據機呼叫僅支援站ID。

設定

本文檔使用如下所示的配置。

  • 池範圍內的多個資料機

  • 池中的一個數據機

  • 沒有池範圍的數據機池

本節提供用於設定本文件中所述功能的資訊。

注意：要查詢有關本文檔中使用的命令的其他資訊，請使用命令查詢工具

網路圖表

本文檔使用下圖所示的網路設定。

配置1:池範圍內的多個資料機

疑難排解技術筆記

客戶撥打5557528並連線到池範圍為3到5的數據機。在路由器提示(>)中輸入登入使用者ID和口令後，已將第3到5行配置為自動命令telnet使用者到特定IP地址。

caution 注意：配置被叫號碼功能且不輸入max-conn號碼時，Cisco路由器會預設選擇池中的數據機數。在此組態範例中，資料機3至5的設定方式如下：Cisco IOS軟體在called-number指令的尾端插入max-conn 3。

如果更改池中的數據機數，則必須手動更改max-conn數。

此示例配置使用本地身份驗證。
