簡介

本文提供在Cisco 1600、1700、2600和3600路由器上使用同步和非同步埠進行數據機撥入的示例配置。通過下列配置，可以將路由器的同步和非同步介面連線到使用DB-60到RS-232電纜連線到路由器的外部客戶端數據機。

註：如果您有USR sportster數據機，則只有dip開關3和8應該關閉。

請注意，在介面上配置物理層非同步後，需要配置的配置中出現新的行號（在本例中為104）。 如果您不知道哪個行號與哪個介面相關聯，請發出show line EXEC命令檢視對映。完成所有這一切配置並安裝所有硬體後，必須反向Telnet到數據機以鎖定兩台裝置之間的資料終端裝置(DTE)速度。為此，請通過Telnet連線到埠號為2000+x且處於up/up狀態（環回介面非常適合此情況）的機箱上的任何IP地址，其中x是數據機所連線的線路號。在本例中，數據機位於104線路上，因此Telnet到環回地址(1.1.1.1)埠2104。然後，您可以在空白行發出AT命令，數據機應回應要求的「OK」。 要斷開連線，請點選Ctrl-Shift-6，然後點選x以返迴路由器提示，然後鍵入disconnect以關閉連線。

注意：請確保關閉連線或連線無法正常工作。

例如：

router1#telnet 1.1.1.1 2104
Trying 1.1.1.1, 2104 ... Open
at
OK
router1#disconnect
Closing connection to 1.1.1.1 [confirm]
router1#

有時，您需要在DTE速度完全鎖定之前，向數據機發出at&b0&w0命令。反向Telnet完成後，使用超級終端機（或其他ASCII程式）撥號到路由器，看看您是否可以取得路由器提示。設定應為8N1。如果這樣有效，則PPP連線也應有效。

驗證

本節提供的資訊可用於確認任何佈線問題。以下是同步/非同步卡的佈線圖。此外，請確保您數據機硬體在行(104)下的狀態與下面所解釋的類似。 

Sync/async port(DB60 female)<------( CAB-232MT=, Part# 72-0793-01)-------->External Modem

註：CAB-232MT電纜是DTE電纜，它使路由器充當DTE裝置。您需要它才能連線到數據機（DCE裝置）。 如果將同步/非同步埠連線到終端裝置(DTE)，則需要使用DCE電纜(CAB-232FC=)，使路由器充當DCE裝置。

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。

疑難排解

上述驗證部分提供了有關電纜連線和非同步通訊控制訊號(CTS DSR DTR RTS)的大部分資訊。使用Router 1的上述組態時，使用者應該可以撥號。

  • EXEC模式 — 在EXEC模式下，使用者可以使用串列終端實用程式（如hyperterm/procomm）從數據機撥號到連線到同步/非同步埠的外部數據機。在數據機之間成功進行培訓後，使用者應獲得router1提示。檢驗部分中的所有上述show命令是在與路由器的EXEC連線期間收集的。

  • PPP模式 — 在PPP模式下，使用者可以從使用Windows撥號網路的數據機撥號到在同步/非同步埠上連線的外部數據機。如果在EXEC模式下撥號正常，則PPP也應正常工作。請確保配置與上述完全相同。要對PPP模式進行故障排除，請使用以下debug命令撥入，這些命令需要與毫秒時間戳一起開啟。按照粗體顯示的調試行檢視調試的進度。如果您需要更多資訊，請使用以下PPP故障排除流程圖。

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。

  • service timestamps debug datetime msec — 用於為調試啟用毫秒時間戳。

  • debug modem — 用於觀察接入伺服器上的數據機線路活動。

  • debug ppp negotiation — 用於檢視客戶端是否正在傳遞PPP協商。

  • debug ppp authentication — 用於檢視客戶端是否正在傳遞身份驗證。

  • debug chat — 用於顯示聊天指令碼活動。

  • debug confmodem — 用於顯示與連線到路由器的數據機的發現和配置相關的資訊。

  • show debugging — 用於顯示有關為路由器啟用的調試型別的資訊。

  • show users — 用於顯示路由器上活動線路的資訊。
