求救，SDH问题

sdasdf

3Q，等下面的割接再看

puding

让运营商给你拿台METRO1000之类的设备来测。

ssffzz1

这个东西和METRO1000有啥关系啊？？？要运营商测的话也是用流量来测。

从你的配置中我发现了一个问题，但是不确定和目前的故障现象有直接关系，算是一个隐患吧。
1.
controller SONET 1/0
framing sdh
clock source internal
运营商的SDH网络是提供精准时钟（好像是铷钟或者是铯钟）的，所以还是建议你复原为clock source line---这也是默认的配置。

2.
au-4 1 tug-3 1
  tug-2 1 e1 1 unframed
虽然运营商给CPOS提供了时钟，但是CPOS里面的2M是PDH的，说白了就是木有时钟，所以建议你在核心点为每一个2M设置为clock source internal，分支点保持默认设置clock source line.

谢谢楼上的！到时候我也试一下

qu：能给我们详细讲讲这个时钟的问题吗？？ 我有点搞不清楚。

quxiaosong

我也不是搞传输的，就说说我粗浅的理解吧。咱们熟悉IP的内容吧，那些header能标识出如何一层层解封装，因为每个包的内容有可能是tcp的，或者是udp的，端口号也不同，对应着不同的应用。在传输上，是靠时钟的。即SDH标准中约定了每个时刻传什么样的东西。如果每台设备都各自为政，按照自己的时钟来工作，那么一旦偏差大了，相互的配合就有问题了。在生活中，咱们有个约会啥的，也有类似的问题，解决办法就是让各自的手表和CCTV对时。虽然没有绝对的准确，约会晚个几分钟没啥，但是严重迟到媳妇儿就该怒了。
回到SDH上，在一条专线上，最合理的情况就是有且只有一个主时钟，其他设备与之同步，这样大家就能步调一致地协同工作了。
在这个帖子中，咱们先看CPOS。SDH的网络中，STM-1是有时钟的，且由运营商的网络提供（很精准）。那么作为客户端路由器，就很自然地遵从这个时钟。所以在CPOS下，保持默认设置：clock source line.这个show run 看不到，需要show controller才看得到。
再来看看2M，由于SDH设备无法为2M线路提供时钟，那么就只能客户自力更生了。即一端使用设备内部的时钟（没有运营商的准，但是也木有办法），另一端从线路信号中提取时钟频率，在发送信号时使用。
说了正确的配置，再说说错误的。错误有2种：
1.两端都使用设备内部的时钟，即主时钟。如果他们都十分准确，误差小，那就没啥问题，如果误差大，那工作起来就猴吃麻花了，就像跳交谊舞，一个人慢4，另一个人快3，非打起来不可。
2.两边都是line时钟，即从时钟。我们知道，绝对的精准是不存在的，总要有一些误差。比如A端以+1的误差发送信号，B端收到后把这个信号作为基准，再叠加上自己本身的误差假设也是+1，发送信号。时间一长，A和B在错误的道路上越走越远，严重偏离了2048k这个频率，那必然无法工作了。
是不是有些像NTP？指定一个时钟源（通常是运行稳定的高端设备），其他设备都与之同步，这样系统的log才便于比对。
敲了这么多，也不知道说清楚没有，大家凑合看吧，哈哈！

谢谢楼上的  下星期二就被弄去顶了
按照你说的意思 就是2个地方的时钟设置要反一下对吧

show controller这些信息够不够 大家再看看 谢谢

这个信息太多了，show controller sonet 1/0比较好，能清楚地看见有啥告警，比如LOS、AIS等等。不过你show出来的内容，还是可以看出来时钟是internal，当然这个show run也能看见，默认是line,show run 就不显示了。

下星期去我再抓一下

SONET 1/0 is up.
  Hardware is single mode intermediate reach adapter
  H/W Version : 24.257.2.5, ROM Version : 1.2, F/W Version : 1.19.0
  FREEDM version: 2, reset 0
  Applique type is Channelized Sonet/SDH
  Clock Source is Internal, AUG mapping is AU4.

红色的改为line试试，即跟ISP同步时钟。


SONET 1/0   E1   1/1/1/1 is down
  Framing is none, Clock Source is line.

红色的改为internal试试，即hub的给spoke的提供时钟，然后spoke不用修改，为默认即可。

我的理解没问题吧。
