CISCO CPOS STM配置示例.doc

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STM1E1 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N64K的channelgroup的形式。根据ITUT的G。703的定义，国际上流行的STM复用技术主要以下两种：a,E1C-12VC-12TU-12 x3TUG-2 x7VC-3AU-3 x3AUGSTM-1b,E1C-12VC-12TU-12 x3TUG-2 x7TUG-3 x3VC4AU4AUGSTM-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，一个E1的祯首先被装进一个叫做C-12的容器，再被装进VC-12的容器，然后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VIP2和以下版本的VIP板卡不支持STM1模块。2， 一块STM1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 x3TUG-2 x7TUG-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 TUG3 TUG2 TU12 E1时隙 1 1 1 1 1 11 1 2 2 1 1 1 3 3 1 1 2 1 4 1 1 2 2 5 11 2 3 6 11 3 1 7 11 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3Router(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TUG3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 serialslot/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0Router(config-if)#ip address 16.202.99.165 255.255.255.255Router(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N64K的时隙，就可以配置成unframed格式，比较省事，但是要注意最后的E1V。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 runBuilding configuration.Current configuration : 9365 bytes!

CPOS（通道化POS）模块模块概述CPOS是通道化SDH/SONET接口模块的简称，其中C表示Channelized，POS表示Packet Over SDH/Sonet。它充分利用了SDH体制的特点，提供对带宽精细划分的能力，可减少组网中对路由器低速物理接口的数量要求，增强路由器的低速接口汇聚能力，并提高路由器的专线接入能力。1CPOS支持1个STM-1/OC-3多通道接口模块，支持155.52Mbps的通信速率。1CPOS接口卡分为1CPOS（E）和1CPOS（T）两种型号，其中1CPOS（E）接口卡支持E1制式，而1CPOS（T）接口卡支持T1制式。1CPOS接口模块分别提供用于AR 28系列的RT-1CPOS（E）、RT-1CPOS（T）和用于AR 46系列的RT-FIC-1CPOS（E）、RT-FIC-1CPOS（T）模块，通过PCI接口与CPU进行通讯，完成STM-1通道化POS接口数据的收发。其特点如下：l 支持净通道（非成帧）E1（最多63个）或T1（最多84个）。l 支持非通道化（成帧）E1（最多63个）或T1（最多84个）。l 支持通道化到64K，但是最多256个逻辑通道。使用方法目前CPOS接口只实现E1、T1向STM-1的复用。实际应用中，不同的国家和地区可能采用不同的复用路径，为保证互通， CPOS提供multiplex mode命令，使用户可以选择AU-3（即E1制式）还是AU-4（即T1制式）复用路径（我国SDH体制选用的是AU-4的复用路径）。在目前的实现中，CPOS通道化出的E1支持净通道（clear channel，又称为非成帧模式，unframed）和非通道化（unchannelized）两种工作模式。在净通道模式下，E1通道不分时隙，形成一个速率为2.048Mbps的串口（相当于一个2.048Mbps的同步串口）。在非通道化模式下，E1通道除时隙0以外的31个时隙可以捆绑为一个串口使用（相当于一个E1-F端口）。CPOS通道化出的T1支持净通道和通道化（channelized）两种工作模式。在净通道模式下，T1通道不分时隙，形成一个速率为1.544Mbps的串口（相当于一个1.544Mbps的同步串口）。在通道化模式下，T1通道的24个时隙可以任意捆绑为串口使用（相当于一个cT1端口），在这种情况下可以通道化到64Kbps，但是最多支持256个逻辑通道。KF_WSX_DCR6004_R_01_config#sh ruBuilding configuration.Current configuration:!service timestamps log dateservice timestamps debug dateno service password-encryption!hostname KF_WSX_DCR6004_R_01!isdn switch-type basic-5ess!controller E1 1/0unframed!controller CPOS 2/0au-4 1 tug-3 1 tug-2 1 e1 1 unframed tug-2 1 e1 2 unframed tug-2 1 e1 3 unframed tug-2 2 e1 1 unframed tug-2 2 e1 2 unframed tug-2 2 e1 3 unframed tug-2 3 e1 1 unframed tug-2 3 e1 2 unframed tug-2 3 e1 3 unframed tug-2 4 e1 1 unframed tug-2 4 e1 2 unframed tug-2 4 e1 3 unframed tug-2 5 e1 1 unframed tug-2 5 e1 2 unframed tug-2 5 e1 3 unframed tug-2 6 e1 1 unframed tug-2 6 e1 2 unframed tug-2 6 e1 3 unframed tug-2 7 e1 1 unframed tug-2 7 e1 2 unframed tug-2 7 e1 3 unframed exitau-4 1 tug-3 2 tug-2 1 e1 1 unframed tug-2 1 e1 2 unframed tug-2 1 e1 3 unframed tug-2 2 e1 1 unframed tug-2 2 e1 2 unframed tug-2 2 e1 3 unframed tug-2 3 e1 1 unframed tug-2 3 e1 2 unframed tug-2 3 e1 3 unframed tug-2 4 e1 1 unframed tug-2 4 e1 2 unframed tug-2 4 e1 3 unframed tug-2 5 e1 1 unframed tug-2 5 e1 2 unframed tug-2 5 e1 3 unframed tug-2 6 e1 1 unframed tug-2 6 e1 2 unframed tug-2 6 e1 3 unframed tug-2 7 e1 1 unframed tug-2 7 e1 2 unframed tug-2 7 e1 3 unframed exitau-4 1 tug-3 3 tug-2 1 e1 1 unframed tug-2 1 e1 2 unframed tug-2 1 e1 3 unframed tug-2 2 e1 1 unframed tug-2 2 e1 2 unframed tug-2 2 e1 3 unframed tug-2 3 e1 1 unframed tug-2 3 e1 2 unframed tug-2 3 e1 3 unframed tug-2 4 e1 1 unframed tug-2 4 e1 2 unframed tug-2 4 e1 3 unframed tug-2 5 e1 1 unframed tug-2 5 e1 2 unframed tug-2 5 e1 3 unframed tug-2 6 e1 1 unframed tug-2 6 e1 2 unframed tug-2 6 e1 3 unframed tug-2 7 e1 1 unframed tug-2 7 e1 2 unframed tug-2 7 e1 3 unframed exit!aaa authentication login default lineaaa authentication enable default enableenable password 0 hnnx level 15!interface Loopback0ip address 11.149.31.3 255.255.255.255no ip directed-broadcast!interface FastEthernet0/0description YingYeBuip address 11.149.192.1 255.255.255.240no ip directed-broadcast!interface GigaEthernet0/1description QianZhiJiip address 11.149.35.254 255.255.255.0no ip directed-broadcast!interface GigaEthernet0/2no ip addressno ip directed-broadcast!interface Serial1/0:0description KaiFengShi-WTip address 11.145.225.14 255.255.255.252no ip directed-broadcastencapsulation ppp!
