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

在許多環境中，必須配置接入伺服器以接受來自非同步和ISDN使用者的來電。這些使用者將可以無縫連線到網路，就像物理存在一樣。因此，此設定通常用於為出差和遠端辦公的使用者以及小型辦公室 — 家庭辦公室(SOHO)站點提供網路連線。

必要條件

採用元件

本文中的資訊係根據以下軟體和硬體版本：

Cisco AS5400配備兩個撥號功能卡(DFC)，提供216個NextPort數據機和8個T1卡。
Cisco IOS®軟體版本12.3 Mainline。
一個活動T1 PRI。
本機驗證、授權及記帳(AAA)。如果您有AAA Radius或Tacacs+伺服器，則可以使用該伺服器為傳入呼叫提供AAA。

此配置僅適用於基本模擬和ISDN撥入。因此，AS5350和AS5400上支援的任何Cisco IOS軟體版本就足夠了。若要執行其他功能，請參閱Software Advisor工具(僅供註冊客戶使用)以選擇適合您需求的Cisco IOS版本和功能集。

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。

背景資訊

本文檔介紹如何配置AS5350或AS5400系列接入伺服器以接受ISDN T1 PRI電路上的傳入非同步和ISDN呼叫。此配置僅包括網路接入伺服器(NAS)接受呼叫所需的最低配置。您可以根據需要向此配置新增功能。

定義相關流量和空閒超時

NAS只處理來電，不進行出站呼叫，但我們仍然定義感興趣的流量。相關流量定義對於非同步使用者和ISDN使用者有不同的用途。

對於ISDN使用者（對應於介面撥號程式1）：

無論您是否要強制使用空閒超時，撥號器介面上都需要使用dialer-group和dialer-list命令。撥號器介面上需要dialer-group和dialer-list指令以避免封裝失敗。此要求僅適用於ISDN使用者，不適用於非同步使用者和組非同步介面。

要強制執行空閒超時，請新增dialer in-band和dialer idle-timeout命令。如果配置了dialer in-band，但沒有dialer idle-timeout，則ISDN使用者的空閒超時預設為兩分鐘。

如果您希望ISDN使用者能夠在選擇斷開連線之前保持連線，請使用dialer idle-timeout 0。dialer idle-timeout的「零」選項是在Cisco IOS軟體版本12.1(3)T中引入的。它設定無窮大的超時。

對於非同步使用者（對應於Interface Group-Async 0）：

要為非同步使用者強制實施空閒超時，請在組非同步介面中配置以下命令：dialer in-band、dialer idle-timeout和dialer-group。相應的dialer-list也是必需的。dialer-group和dialer-list命令指定group-async-interface上的相關流量。

對於非同步使用者，相關流量僅用於重置空閒超時。如果沒有定義相關流量，則在dialer idle-timeout（預設120秒）到期後，無論使用者是否正在鏈路上傳遞流量，都將斷開連線。通過有意義的流量定義， NAS可以識別這些資料包並重置空閒超時。這樣，只有在真正存在空閒鏈路時，NAS才會斷開使用者的連線。

您可以修改感興趣的流量，例如只關注HTTP(Web)流量。在這種情況下，如果使用者在300秒(或指定的dialer idle-timeout)內未瀏覽Web，則使用者將斷開連線。根據使用者的流量模式配置感興趣的流量。

如果您希望非同步使用者能夠保持連線，直到他們選擇斷開連線，請從group-async-interface中刪除以下命令：dialer in-band、dialer idle-timeout和dialer-group，如配置所示。您也可以使用dialer idle-timeout 0的幫助將閒置逾時設定為無窮大。dialer idle-timeout的「零」選項是在Cisco IOS軟體版本12.1(3)T中匯入，而且會設定無限的逾時。

驗證

本節提供的資訊可用於確認您的組態是否正常運作。

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

show isdn status — 確保路由器與ISDN交換機正確通訊。在輸出中，驗證第1層狀態是否為ACTIVE，以及是否顯示第2層狀態狀態= MULTIPLE_FRAME_ESTABLISHED。此命令還顯示活動呼叫的數量。
show ppp multilink — 顯示處於活動狀態的多鏈路捆綁的資訊。使用此命令驗證多鏈路連線。
show dialer [interface type number] — 顯示為DDR配置的介面的常規診斷資訊。如果撥號器正常啟動，Dialer state is data link layer up消息必須出現。如果顯示實體層啟用，則表示線路通訊協定已啟動，但網路控制通訊協定(NCP)未啟動。發起撥號的資料包的源地址和目的地址顯示在撥號原因行中。此show命令也會顯示計時器的設定以及連線超時之前的持續時間。
show caller user username detail — 顯示特定使用者的引數，例如分配的IP地址、PPP和PPP捆綁引數等。如果您的Cisco IOS軟體版本不支援此命令，請使用show user命令。
show dialer map — 顯示配置的動態和靜態撥號器對映。此命令可用於檢視是否建立了動態撥號器對映。如果沒有撥號器對映，則無法路由資料包。

以下是成功呼叫的一些show命令輸出。請注意粗體字部分以及輸出示例中提供的註釋。將您獲得的輸出與此處顯示的結果進行比較。

疑難排解指令

輸出直譯器工具(僅供註冊客戶使用)支援某些show命令，此工具可讓您檢視show命令輸出的分析。

注意：發出debug指令之前，請先參閱有關Debug指令的重要資訊。

debug dialer — 顯示有關撥號器介面上接收的資料包的DDR調試資訊。此資訊有助於確儲存在可以使用撥號器介面的有趣流量。
debug isdn q931 — 顯示ISDN網路連線（第3層）的呼叫建立和斷開。
debug modem — 顯示接入伺服器上的數據機線路活動。輸出指示數據機線路何時更改狀態。
debug csm modem — 用於排除帶有內部數字數據機的路由器上的呼叫交換模組(CSM)問題。使用此命令，您可以跟蹤切換呼入和撥出呼叫的完整順序。

註：這相當於debug modem csm on the AS5200/AS5300。此調試是在Cisco IOS軟體版本12.0(4)XL中匯入。
debug ppp negotiation — 在鏈路控制協定(LCP)、身份驗證和網路控制協定(NCP)協商期間顯示有關PPP流量和交換的資訊。成功的PPP協商將首先開啟LCP狀態，然後進行身份驗證，最後協商NCP。在LCP協商期間建立諸如最大接收重建單元(MRRU)的多鏈路引數。
debug ppp authentication — 顯示PPP身份驗證協定消息，包括質詢握手身份驗證協定(CHAP)資料包交換和口令身份驗證協定(PAP)交換。
debug ppp error — 顯示與PPP連線協商和操作相關的協定錯誤和錯誤統計資訊。
