無偏見用語

本產品的文件集力求使用無偏見用語。針對本文件集的目的，無偏見係定義為未根據年齡、身心障礙、性別、種族身分、民族身分、性別傾向、社會經濟地位及交織性表示歧視的用語。由於本產品軟體使用者介面中硬式編碼的語言、根據 RFP 文件使用的語言，或引用第三方產品的語言，因此本文件中可能會出現例外狀況。深入瞭解思科如何使用包容性用語。

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

在此配置中，有兩個不同的X.25資源（我們使用dspu-host來模擬此設定中的終端裝置）。 有關下游實體裝置(DSPU)的詳細資訊，請參閱以下檔案：

這兩個終端裝置通過X.25與大型機站點中的不同介面卡進行通訊。遠端X.25資源被配置為使用不同的目標地址（使用不同的長度和地址）。 X.121目的地位址與路由器的「qllc dlsw子位址」相匹配的任何傳入呼叫都會被分派到資料連結交換Plus(DLSw+)（具有ID.STN IND）。 當DLSw+收到有關池中虛擬MAC地址的「你能到達」查詢時，限定邏輯鏈路控制(QLLC)代碼會嘗試將虛電路(VC)設定為對映到指定的虛擬MAC地址的X.121地址。如果收到來電，QLLC會將具有虛擬MAC地址的ID.STN.IND從池傳送到DLSw+。
