标题: 急求帮助，神州数码2626路由器ppp连接问题
做个实验。\r\n两台2626串口通过一拖二的线缆连接，一台的用cr-2-v35fc 一台用cr-2-v35mt .死活都是serial down,协议也是down的。必须要做multilink？试着做了也不行。\r\n到底要怎么做。后板上有s1,s2,s3,s4指示灯一个都不亮。急啊\n\n[ 本帖最后由 unixyeah 于 2009-2-18 11:02 编辑 ]

帖接口状态，确认一段是DTE另一端是DCE.

dte dce应该是不会搞错\r\nfc-接的定为dce 时钟64000\r\nmt-接的定为dte\r\n\r\n我想在就作最简单的hdlc 还是ppp也好\r\n都是down

帖接口状态。\r\n\r\n这个不用太啰嗦吧。\r\n\r\n如果DTE和DCE正确，配置也没问题的话，没理由不UP的。

不好意思，这会别人在用。要不我就贴了，呵呵。

A s0/1 s0/2\r\n | |\r\nB s0/1 s0/2\r\n 判断不出来s0/1对s0/1还是s0/1对s0/2，但这应该不影响lserial up吧。而且我撤掉一根，还是down。\n\n[ 本帖最后由 unixyeah 于 2009-2-18 11:02 编辑 ]

DTR=UP,DSR=DOWN,RTS=UP,CTS=DOWN,DCD=DOWN\r\n\r\n从这个地方可以看到物理信号都没有UP。\r\n1、要么是DTE和DCE电缆不对。\r\n2、要么是接口物理故障（一般不太可能）。\r\n\r\n因此认为你再确认电缆正确性比较好。

作者: unixyeah 时间: 2009-02-18 10:01
我这里有个疑问 dte dce怎么都是DTR=UP,DSR=DOWN,RTS=UP,CTS=DOWN,DCD=DOWN

作者: ssffzz1 时间: 2009-02-18 10:08
CISOCO和H3C的都一个忽略DSR（好像是）信号的命令，你可以试试。不过感觉希望不大。

作者: ssffzz1 时间: 2009-07-19 11:17
晕死，说过检查线缆了。\r\n\r\nDCE对DCE了啊。\n\n[ 本帖最后由 ssffzz1 于 2009-7-19 11:20 编辑 ]
