【正文】 protocol is up physical layer is synchronous interface is DTE, clock is DTECLK1, cable type is V35 Maximum Transmission Unit is 1500 Internet address is Linkprotocol is PPP LCP opened, IPCP opened, IPXCP initial, CCP initial, BRIDGECP initial 5 minutes input rate bytes/sec, packets/sec 5 minutes output rate bytes/sec, packets/sec Input queue : (size/max/drops) 0/50/0 FIFO queueing: FIFO Output queue: (size/max/drops) FIFO: 0/75/0 input packets:39, bytes:1040, no buffers:0 output packets:40, bytes:1064, no buffers:0 input errors:0, CRC:0, frame errors:0 overrunners:0, aborted sequences:0, input no buffers:0 DCD=UP DTR=UP DSR=UP RTS=UP CTS=UP PPP故障的診斷與排除1. 故障之一：鏈路始終不能轉(zhuǎn)為Up狀態(tài)。故障排除：可能是由于 PPP驗(yàn)證參數(shù)配置不正確，導(dǎo)致PPP驗(yàn)證失敗。打開PPP的調(diào)試開關(guān)，會(huì)看到LCP協(xié)商成功并轉(zhuǎn)為 Up 狀態(tài)后進(jìn)行PAP 或CHAP 協(xié)商，然后LCP轉(zhuǎn)為 Down 狀態(tài)。2. 故障之二：物理鏈路不能轉(zhuǎn)為Up狀態(tài)。故障排除：可以執(zhí)行display interface serial number命令來查看接口當(dāng)前狀態(tài)。接口有五種狀態(tài)：serial number is administratively down, line protocol is down表示該接口被shutdown。serial number is down, line protocol is down表示該接口沒有被激活或物理層沒有轉(zhuǎn)為UP狀態(tài)。serial number is up, line protocol is up(spoofing)表示該接口是撥號口，沒有呼通。serial number is up, line protocol is up 表示該接口已可以進(jìn)行數(shù)據(jù)傳輸。serial number is up, line protocol is down表示該接口已激活，但鏈路協(xié)商仍沒有通過。15
