CISCO CPOS STM配置示例

CISCO CPOS STM配置示例 此次XXX行营业部到部分支行和网点的广域网线路改造采用了STM1,E1 的连接形式，下面我把这次线路调试的一些经验和心得介绍给大家，希望能够对大家日后的工作有所帮助。如果这篇文档中有什么不足或 者不对的地方，还希望大家能够指出。 一，STM1介绍: STM，Synchronous Transport Module，是基于电信SDH骨干网传输的一种时分复用 技术，与CE1线路很类似。说的简单点，一个STM模块就是一个多通道的E1模块。一个STM模块可以配置为最大支持63个E1线路，而每一个E1线路可以根据用户的需要配置为2M的带宽，或者再细分成N×64K的channel,group的形式。 根据ITU,T的G。703的定义，国际上流行的STM复用技术主要以下两种: a,E1――C-12――VC-12――TU-12 x3――TUG-2 x7――VC-3――AU-3 x3――AUG――STM-1 b,E1――C-12――VC-12――TU-12 x3――TUG-2 x7――TUG-3 x3――VC,4――AU,4,AUG――STM-1 目前中国的电信多采用第二种复用路径，一般习惯成为373复用,简单的理解， -12的容器，再被装进VC-12的容器，然后一个E1的祯首先被装进一个叫做C 形成一个叫做附属单元的东东(tu-12)，然后三个tu-12被复用成一个附属单元组tug-2，接下来7个tug-2被复用成一个更大的单元组，叫做tug-3，后面再用一个叫做VC-4的更大的容器装下3个tug-3，转换为一个au-4,在经过转化，最后成为STM的祯格式(有点晕:()。 在给客户安装时需要注意: 1， CISCO7507的VIP,2和以下版本的VIP板卡不支持STM,1模块。 2， 一块STM,1模块最多只能划分256个channel group。 3， 有些高版本的IOS并不支持STM卡，如果装上去无法识别，可以适当的调整IOS的版本。 二，PA-MC-STM-1的配置 由于电信提供的STM/E1的服务是基于SDH这种透明的传输技术的，所以STM的配置很简单，而且很多参数可以我们自己定制，而不需要电信提供，比如E1的数据祯是否成祯，具体成祯的格式等等。 在此次xx电信提供的工单上只有一个叫做时隙的参数，比如从省行营业部到五一路支行是用第1个时隙传输，到湖大支行用第2时隙传输…..到白沙路支行使用第63时隙传输，所以我们首先要搞清楚这个时隙与具体的TU-12 x3――TUG-2 x7――TUG-3 x3的对应关系(CISCO的配置必须要知道这个对应 关系，否则无法配置，而华为的CPOS卡则只需要知道时隙就可以了)，才能 在STM模块上做具体的配置，一般的对应关系如下 AUG TUG,3 TUG,2 TU,12 E1时隙 1 1 1 1 1 1 1 1 2 2 1 1 1 3 3 1 1 2 1 4 1 1 2 2 5 1 1 2 3 6 1 1 3 1 7 1 1 3 2 8 1 1 3 3 9 1 1 4 1 10 1 1 4 2 11 1 1 4 3 12 以下依次类推: 1 3 7 3 63 下面是具体的配置步骤: Router(config)# controller sonet 8/0/0 -进入STM模块的配置模式 Router(config-controller)# framing SDH -定义STM的祯模式(一共有SDH 和sonet两个参数，SDH是默认值) Router(config-controller)# aug mapping au-4 ??-定义使用的复用路径(一共有au-3和au-4两个参数， au-4是默认值) Router(config-controller)# au-4au-4-numbe tug-3tug-3-number , 配置指定的tug-3，其中au-4-number 永远为1，tug-3-number为1到3 Router(config-ctrlr-tug3)# mode c-12 定义一个tug-3可以被分为21个tu-12,每一个tu-12可以承载一 个E1线路 Router(config-ctrlr-tug3)# tug-2 tug-2-number e1 e1-number unframed 在一个TUG,3上建立一个非成祯的逻辑E1通道 在做完这个配置后，路由器会虚拟出一个串口来，这点与CE1线路很类似，简单的理解一个串口就是一个TU-12 ――TUG-2 ――TUG-3的复用关系，也就是一个2M线路，对应电信提供的一个时隙 Router(config)# interface serial slot/port-adapter/port.au-4-number/tug-3-number/tug-2- number/ e1-number:channel-group-number 进入这个串口的配置模式，对于非成祯的E1线路，channel-group-number永远为0 Router(config-if)#ip address 16.202.99.165 255.255.255.255 Router(config-if)# encapsulation ppp 在串口的两端封装PPP 三，配置总结: 1， 首先要搞清楚时隙对应关系，这个可以按照上面的 表 关于同志近三年现实表现材料材料类招标技术评分表图表与交易pdf视力表打印pdf用图表说话 pdf 自己计算，如果不放心的话可以让电信帮助查。(在他们的设备上可以查出，但是他 们一般懒的提供给客户) 2， 对于E1的祯格式，可以成祯，也可以不成祯，如果客户不要求在E1线路上再划分具体的N×64K的时隙，就可以配置成unframed格式，比较省事，但是要注意最后的E1,V。35转换器的开关设置。 3， 对于线路时钟，可以使用电信的SDH网提供的时钟，另外CISCO的STM卡也可以提供时钟，看自己的爱好了。 4， 在配置串口上，一定要记住两端都要封装PPP，否则不通，CISCO路由器串口的默认封装为HDLC。 下面是xxx行营业部路由器的show run Building configuration...
