思科Cisco 交换机型号概述
思科Cisco 交换机型号概述思科Cisco 交换机的命名一般是WS开头这个是固定的，再下一个字母有两种一个是C一个是X，C代表固化交换机或者机箱，X代表的是模块。
比如看到WS-C3750-24TS-S这个型号的时候我们应该知道他是CISCO交换机.固化交换机3750系列，24个以太网口，TS表示是以太口+SFP口后面的S表示是标准版的，相应的型号就是E的，属于增强型或者叫企业版。
再如WS-X6748-SFP，WS还是代表交换设备，x表示模块，6表示6000系列，7表示7代产品，48表示48口，SFP 表示端口类型。
Cisco交换机有以下几个系列：1900系列：19242900系列：2924、2924M2950系列：2950-24、2950G-24/48、2950C-24、2950T-24、2950SX-24/48 2960系列：2960-24/48TT-L、296024/48TC-L3500系列：3508G、3524、35483550系列：3550-24-SMI/EMI、3550-48-SMI/EMI、3550-12G/T3560系列：3560-24/48也有带G的3750系列：3750-24/48-TS-S、3750-24/48-TS-E 3750G-24/48-TS-S、3750G-24/48-TS-E 、3750G-12S4000系列：4003、40064500系列：4503、4506、4507R6000系列：6006、60096500系列：6506、6509、65137600系列：7609、7613可扩展性分类Cisco的交换机产品以“Catalyst”为商标，包含1900、2800、2900、3500、4000、5000、5500、6000、8500等十多个系列。
总的来说，这些交换机可以分为两类：一类是固定配置交换机，包括3500及以下的大部分型号，比如1924是24口10M以太交换机，带两个100M上行端口。
cisco路由器常用的查看端口和通道状况的命令
cisco路由器常⽤的查看端⼝和通道状况的命令cisco路由器常⽤的查看端⼝和通道状况的命令cisco, 路由器, 端⼝, 通道, 命令下⾯以Cisco1800路由器为例，介绍⼀下常⽤的查看端⼝和通道状况的命令。
在MS-DOS 窗⼝⾥敲⼊命令telnet+IP地址，回车，即可远程登录路由器。
⼀般⽤路由器局域⽹⼝地址。
1，⽤R1#sh ip int b命令查看端⼝状态R1#sh ip int bInterface IP-Address OK? Method Status ProtocolFastEthernet0/0 100.100.100.226 YES NVRAM up upFastEthernet0/1 200.200.200.226 YES NVRAM up upSerial0/0/0 72.22.81.102 YES NVRAM up upSerial0/0/1 72.22.81.109 YES NVRAM up up正常情况下，思科1800路由器四个端⼝的Status和protocol都是up的。
2，⽤R1#sh int s0/0/0查看链路状态和通道情况Serial0/0/0 is up, line protocol is up //接⼝与协议都已启动（正常）Serial0/0/0 is up, line protocol is down //接⼝启动，协议没有匹配成功（端⼝⽆物理故障，但通道不通）Serial0/0/0 is down, line protocol is down （notconnect）//接⼝与协议都DOWN掉,本端端⼝没有与对⽅建⽴物理连接，可能是对⽅设备没有开启，对⽅端⼝故障或者线路故障造成。
Serial0/0/0 is down, line protocol is down //接⼝与协议都DOWN掉（协转没有⼯作）Serial0/0/0 is down,line protocol is down（disable）//端⼝出现物理性故障，需更换端⼝。
浅析FTTH—光纤到户接入技术
浅析FTTH—光纤到户接入技术作者：唐斌来源：《消费电子·理论版》2013年第10期摘要：文中基于FTTH—光纤到户接入技术，主要分析了无源光网络（PON）技术和小区有源交换光网络（Active Optical Network——AON）的点对点（P2P）接入技术。
关键词：FTTH；接入技术；无源光网络；有源交换光网络中图分类号：TN915.63 文献标识码：A 文章编号：1674-7712 （2013） 20-0000-01现有的FTTH技术主要包括无源光网络（Passive Optical Network——PON）接入技术和小区有源交换光网络（Active Optical Network——AON）接入技术，它们各有优势，适合于不同的应用环境。
一、无源光网络（PON）技术PON技术特点：理想无源光网络（简称为PON）的结构及其分布的主要特点为：光线路终端（简称为OLT）是在电信运营商中心机房里，无源光分配器（简称为Splitter）最好是放置在用户端的光网络单元（简称为ONU）临近的地方。
电信运营商中心机房与用户之间的距离也就和光线路终端与用户光网络单元的距离是相等的，通常与固定电话的接入距离差不多，即几公里，无源光分配器与用户光网络单元之间的距离范围在几十米至几百米。
无源光网络的优势也正因此而得到了明显的体现：用户与中心机房之间的整个网络是无源网络，在很大程度上节约了光缆资源，加上是一点对多点的模式，故中心机房的设备得到了精简，其配线也有所减少。
若使用无源光网络的现实布局，目前的光缆资源就足够了，小区机房可以进行统一的配线，无论是放号与维护，还是管理起来都比较简单，用户在运营商选择方面也不再那么单一，设备端口的利用率有了很明显的提高，而其无源网络与光缆资源节省的优势却被放弃了，现在还是存在PON设备价格高及其网络结构较为复杂等不足。
二、小区有源交换光网络（Active Optical Network——AON）的点对点（P2P）接入技术对于较为密集的住宅小区而言，PON的优势丝毫没有得到体现。

做FTTH的意义
全程为无源光网络，在光纤中 传输的光信号几乎不受电磁信 号干扰，所以网络的可靠性更 高,因全程为无源光网络，因此 无电能消耗，降低了运营商的 用电成本
6、光纤到户室内布线（老旧小区）
由于无法在家中的暗管中敷设入户光缆，将可能需要在室内敷设明线。
为保证入户明线的安全美观，并保证光纤的传输性能，多种布线材料供
选择。

B-1Cisco ONS 15454 Reference Manual, R5.078-16296-01A P P E N D I XBAdministrative and Service StatesThis appendix describes administrative and service states for Cisco ONS 15454 cards, ports, and cross-connects. For circuit state information, see Chapter 10, “Circuits and Tunnels.” SoftwareRelease 5.0 states are based on the generic state model defined in Telcordia GR-1093-CORE, Issue 2 and ITU-T X.731.0.1Service StatesService states include a Primary State (PST), a Primary State Qualifier (PSTQ), and one or moreSecondary States (SST). Table 0-1 lists the service state PSTs and PSTQs supported by the ONS 15454.T able 0-1ONS 15454 Service State Primary States and Primary State QualifiersPrimary State, Primary State Qualifier DefinitionIS-NR (In-Service and Normal) The entity is fully operational and will perform as provisioned.OOS-AU (Out-of-Service and Autonomous) The entity is not operational because of an autonomous event.OOS-AUMA(Out-of-Service and Autonomous Management) The entity is not operational because of an autonomous event and has also been manually removed from service.OOS-MA(Out-of-Service and Management) The entity has been manually removed from service.Appendix B Administrative and Service States Administrative StatesTable0-2 defines the SSTs supported by the ONS 15454.T able0-2ONS 15454 Secondary StatesSecondary State DefinitionAINS(Automatic In-Service) The entity is delayed before transitioning to the IS-NRservice state. The transition to IS-NR depends on correction of conditions, or on asoak timer. Alarm reporting is suppressed, but traffic is carried. Raised faultconditions, whether or not their alarms are reported, can be retrieved on the CTCConditions tab or by using the TL1 RTRV-COND command.DSBLD(Disabled) The entity was manually removed from service and does not provide itsprovisioned functions. All services are disrupted; the entity is unable to carrytraffic.LPBK(Loopback) The entity is in loopback mode.MEA(Mismatched Equipment) An improper card is installed. For example, an installedcard is not compatible with the card preprovisioning or the slot. This SST appliesonly to cards.MT(Maintenance) The entity has been manually removed from service for amaintenance activity but still performs its provisioned functions. Alarm reportingis suppressed, but traffic is carried. Raised fault conditions, whether or not theiralarms are reported, can be retrieved on the CTC Conditions tab or by using theTL1 RTRV-COND command.OOG(Out of Group) The virtual concatenation (VCAT) member cross-connect is notused to carry VCAT group traffic. This state is used to put a member circuit out ofthe group and to stop sending traffic. OOS-MA,OOG only applies to thecross-connects on an end node where VCAT resides. The cross-connects onintermediate nodes are in the OOS-MA,MT service state.SWDL(Software Download) The card is involved in a software and database download.This SST applies only to cards.UAS(Unassigned) The card is not provisioned in the database. This SST applies only tocards.UEQ(Unequipped) The card is not physically present (that is, an empty slot). This SSTapplies only to cards.0.2Administrative StatesAdministrative states are used to manage service states. Administrative states consist of a PST and anSST. Table0-3 lists the administrative states supported by the ONS 15454. See Table0-2 for SSTdefinitions.Note A change in the administrative state of an entity does not change the service state of supporting or supported entities.Cisco ONS 15454 Reference Manual, R5.078-16296-01Cisco ONS 15454 Reference Manual, R5.078-16296-01Appendix B Administrative and Service StatesService State Transitions0.3Service State TransitionsThis section describes the transition from one service state to the next for cards, ports, and cross-connects.

Cisco ONS 15454 12-Port和4-Port小型插槽可插拔基于多率光纤传输卡说明说明
Data SheetCisco ONS 15454 12-Port and 4-Port Small Form-Factor Pluggable-Based Multirate Optics CardThe 12-Port and 4-Port SFP-Based Multirate Optics Card for the Cisco® ONS 15454 Multiservice Provisioning Platform (MSPP) improves the platform’s system flexibility, scalability, and economics in multiple-port optical configurations.Product OverviewThe Cisco ONS 15454 12-Port and 4-Port SFP-Based Multirate Optics Card (MRC-12 and MRC-4) supports multiple Small Form-Factor Pluggable (SFP) modules, helping enable multirateSONET/SDH and multiple-reach capabilities. The MRC-12 card (Figure 1) operates in either Cisco ONS 15454 SONET or SDH systems, supporting optical line rates including OC-3/STM-1, OC-12/STM-4, and OC-48/STM-16 and optical reaches from short-reach/interoffice to long-reach/long-haul, including dense wavelength-division multiplexing (DWDM) and coarse wavelength-division multiplexing (CWDM). There are two versions of the MRC-12 card for SDH systems, limited to 10 Gbps and 2.5 Gbps of bandwidth capacity, respectively. The MRC-4 (Figure 2) operates only in Cisco ONS 15454 SONET systems, but at the same optical line rates and optical reaches, with up to 2.5 Gbps bandwidth.Figure 1. MRC-12 CardFigure 2. MRC-4 CardThe MRC cards, depending upon the selected SFP, can carry concatenated payloads of STS-3c/VC-4, STS-6c/VC-4-2c, STS-12c/VC-4-4c, STS-24c/VC-4-8c, and STS-48c/VC-4-16c as well as nonconcatenated payloads on an STS-1, VC-4, VC-3, VC-12, VC-11, and VT1.5 basis. In SONET applications, the cards are software-provisionable to transport SDH payloads over SONET in the form of STS-Nc-concatenated payloads. When operated within the outlined specifications, each card transports signals with a maximum bit error rate of 1 per trillion.The MRC cards are deployable in any of the 12 service interface card slots of the Cisco ONS 15454 MSPP. Their bandwidth also depends upon the cross-connect card operating within the system as well as the interface slot where the cards are installed. Their ports can be commissioned for use in four different architectures – unidirectional-path switched ring/subnetwork connection protection (UPSR/SNCP), 2-fiber and 4-fiber bidirectional line switched ring/multiplex section-shared protection ring (BLSR/MS-SPR), 1+1 automatic protection switching/line multiplex section protection (APS/LMSP), or path-protected mesh network (PPMN) – providing the flexibility to build the type of networks required to meet service demands, traffic patterns, and user needs. This card-provisioning flexibility also helps to reduce the cost of inventory and simplifies engineering and deployment.The MRC cards provide in-service upgrade capabilities from single-port optics cards utilizing the same service slot. They also support line-rate span upgrades through the upgrading of an SFP module.The cards incorporate faceplate-mounted LEDs to provide a quick visual check of the operational status at the card as well as the individual ports. The fan-tray-mounted liquid crystal display (LCD) and soft keys provide the technician local access to the wavelength of each DWDM or CWDM optical port without the need to access the craft manager. Printed on the faceplate is an orange circle icon, which indicates the shelf slot where the card can be physically installed.The card is supported by the integrated Cisco Transport Controller craft manager for the Cisco ONS 15454 MSPP. The controller provides the user with access to operations, administration, maintenance, and provisioning for the system. Access to inventory data for the installed MRC card and pluggable optics modules is available through the craft manager, the Cisco Transport Manager element management system, and Transaction Layer 1 requests.The SFP modules used with the MRC cards are SONET/SDH-compliant (Telcordia Technologies GR-253-CORE and ITU G.957) optical interfaces. The transmitter and receiver reside on the same module and are interconnected to the fiber using small form-factor LC connectors. The SFP modules in the MRC cards support provisionable automatic laser shutdown feature (ITU G.664) to turn off the transmitting laser in the event of a fiber failure on the span. The SFP optical parameters, including laser bias current, optical transmit power, and optical receive power, are available through Cisco Transport Controller to enable simplified troubleshooting and advanced warning of potential impending issues using user-configurable high and low threshold crossing alerts. The SFP cages are angled down relative to the faceplate to reduce bend-induced stresses on the optical fibers exiting the faceplate.The Cisco ONS 15454 12-Port Multirate Optics Card adds significant value to users’ networks by enhancing system flexibility, improving card-slot usage of the shelf assembly, reducing intershelf complexity, and lowering system cost.ApplicationsA Cisco ONS 15454 MSPP equipped with an MRC card provides application solutions for both service providers and enterprise managers, including the two following examples.Multiservice Aggregation and Transport SystemThe high-port-density and multiple-reach support of the MRC-12 card requires fewer cards to perform the same function as multiple fixed-rate/reach cards (Figure 2).Figure 3. MRC-12 Card Frees Up Cisco ONS 15454 Shelf SlotsThe Cisco ONS 15454 shelf slots that are freed up by the MRC-12 card can be used for additional revenue-generating services, such as Fibre Channel, 10/100/1000 Mbps Ethernet, and so on (Figure 4).Figure 4. MRC-12 Card Opens Up New Revenue OpportunitiesThe MRC-12 card also lowers the capital expenditure cost of the Cisco ONS 15454 system by using many optical ports on a common carrier-based card.Network Consolidation NodeReducing network complexity and lowering capital expenditures is a primary need of many businesses. The high port density and multiple-reach support through pluggable optics modules enables users to consolidate network elements as well as simplify operations by reducing internetwork element cabling. Figure 5 shows a traditional service provider network, with access and interoffice networks collecting and transporting traffic. Figure 6 shows the same network using the high-density MRC-12 card.Figure 5. Typical Network DesignFigure 6. Network Consolidation Design with MRC-12 CardThe high-density MRC-12 card with its flexible optical rate and reaches helps consolidate many network elements and significantly reduce the complexity of interworkings between the various networks. Manual cabling by an onsite technician is replaced by electronic cross-connections using the Cisco Transport Controller craft management system from anywhere with network connectivity. This helps improve response times to circuit additions and changes.With its flexibility, density, and wide selection of service modules, the Cisco ONS 15454 MSPP supports a comprehensive mix of applications, allowing a single platform type to meet many business requirements. These capabilities allow users to lower their operational costs by reducing technician training to a smaller base of platform types, reducing sparing requirements, and decreasing service turn-up time for improved revenues.Key Features and BenefitsTable 1 outlines some of the key features and benefits of the MRC-12 card.Table 1. Features and BenefitsFeature BenefitsMultiple-port design Provides cost-effective services aggregation, expands flexibility to support multiple-network hubbing architectures (ring and point-to-point), and frees shelf slots foradditional service cards.SFP module-based More cost-effective sparing of SFP cards than fixed-card alternatives.

Verizon will fill in fiber drops to all FiOS subs and begin turning off copper. ILECs continue growth. Inevitable that AT&T will begin overbuilding with FTTH – will likely “unofficially” cite 1) management change, 2) newly available 2.4 GPON and 3) completion of merger actions. Verizon will continue to build beyond 18 M HP. Verizon switching from BPON to GPON. Qwest begins FTTH builds. MSOs forced to start limited FTTH overbuilds.
