數(shù)據(jù)鏈路連接標識符（DLCI）這個信息包含標識號，它標識多路復用到通道的邏輯連結(jié)。幀中繼交換機將兩端的DLCI關聯(lián)起來，它是幀中繼幀格式中地字段的一個重要部分之一，這是個6位標識，表示正在進行的客戶和服務器之 M層。幀中繼使用DLCI來標識DTE和服務商交換機之間的虛電路。DLCI字段的長度一般為10bit，但也可擴展為16bit，前者用二字節(jié)地址字段，后者是三字節(jié)地址字段。23bit用四字節(jié)地址字段。DLCI值用于標識永久虛電路（PVC），呼叫控制或管理信息。DLCI只具有本地意義。一、使用PacketTracer5.0建幀中繼仿真2811圖二2811圖四2811圖五IPDLCI二、配置Frame以Router2為例，其它兩個路由器相似，＼＼后是人為添加的注釋，在實際配
