思科产品型号分析

思科产品型号分析

思科产品型号分析在思科产品中,路由器是公司的基础产品,交换机是生产最多的产品,还有防火墙产品。

现在我就对这三个主要的思科产品的型号进行分析,方便大家了解!Cisco路由器Cisco路由的命名规则都是以Cisco开头比如:Cisco1841,Cisco2801,Cisco2901,Cisco3745。

这些都是路由器。

比如:Cisco2821 其中Cisco:是品牌,后面的前两位数字是系列号,这款产品属于2800系列,后两位是具体的型号。

其中Cisco路由器有以下几个系列:Cisco2500系列:Cisco2501、Cisco2502、一直到Cisco2514,这些都是国内能见到的设备,再往上就是国外的了,国内很少见到。

Cisco1700:1720、1721、1751、1760Cisco1800:1821、1841Cisco2600系列:2610、2611、2620、2621、2651Cisco2600XM系列:2610XM、2611XM、2620XM、2621XMCisco3600:3620、3640、3660Cisco3700:3725、3745Cisco3800:3825、3845Cisco7200:7204、7206、7204VXR、7206VXR这些都是机箱,使用当中需要引擎的支持(NPE-225、NPE-300、NPE-400、NPE-G1、最新的是NPE-G2)和业务模块的支持。

Cisco7500:7507、7513 同样也需要引擎的支持(RSP2、RSP4、RSP8、RSP16)和业务模块的支持,7200上的业务模块都能在75上使用,需要一块VIP卡的支持。

往上就是12000系列:12008,12016这些是目前最高端的。

同样也需要引擎和业务模块的支持。

Cisco UCS E-Series M1 服务器数据册说明书

Data SheetCisco UCS E-Series M1 ServersWith powerful, data center−class servers that are virtualization-ready, you can host business applications and network services right in your branch-office router.Product OverviewCisco UCS® E-Series Servers bring data center-class blade servers to the branch office. These powerful, small-form-factor, x86 64-bit blade servers reside in Cisco® branch-office routers: the Cisco 4000 Series Integrated Services Routers (ISRs) and Cisco Integrated Services Routers Generation 2 (ISR G2) networking platforms. The blades are virtualization-ready and host essential infrastructure services and mission-critical business applications, all while you maintain a lean branch-office environment (Figure 1).Figure 1. Cisco UCS E-Series Servers with Cisco 4351 ISRProduct DetailsCisco UCS E-Series ServersCisco Unified Computing System™ (Cisco UCS) E-Series Servers are available in two form factors: a singlewide module and a doublewide module. The singlewide versions include an Intel Xeon processor and occupy a single service-module slot in the Cisco 4000 Series ISR and Cisco ISR G2 platforms. The doublewide module occupies two service-module slots side-by-side.All the servers are high-density, single-socket blade servers. They balance simplicity, performance, and application density while operating in an energy-efficient environment. The servers deliver next-generation Intel Xeon processor technology in combination with integrated remote lights-out management. They support multiple cores and threads in a reduced-power envelope, providing improved performance and better energy efficiency than preceding models.They thus provide an excellent platform for introducing virtualization into the branch office and supporting mission-critical business applications. The innovative, zero-footprint form factor of the Cisco UCS E-Series Servers in conjunction with the lower total cost of ownership (TCO) of the Intel Xeon processor increases business agility and enhances reliability when compared to standalone rack-mount and tower servers.Table 1 lists the top-level part numbers for the E-Series servers.Table 1. Cisco UCS E-Series ServersPictureApplications for Cisco UCS E-Series ServersCisco UCS E-Series Servers provide excellent performance and value for these and other types of workloads:●Network applications: Cisco Virtual Wide Area Application Services (vWAAS), Cisco Virtual Wireless LANController (vWLC), Cisco Unity® Connection, Cisco ISR with FirePOWER™ Services, Cisco EnergyManagement, and other Cisco applications●Mission-critical business applications: Point-of-sale (POS) systems, bank teller in-office control points(IOCPs), electronic-medical-record (EMR) systems, inventory management systems, and cloud connectors●Core Microsoft Windows services: Microsoft Active Directory Domain Services (AD DS), Microsoft Windowsprint services, Dynamic Host Configuration Protocol (DHCP) server services, Domain Name System (DNS) server services, and file services●Client-management services: Configuration and operations management, monitoring services, update andpatching services, backup and recovery services, and terminal server gatewaysFeatures and BenefitsThe Cisco UCS E-Series Servers easily extend the Cisco UCS data center portfolio to branch-office environments. By adding virtualization to the servers, you can deploy new services incrementally on a schedule that best meets your timing and budget. Meanwhile, you avoid service-call costs for onsite visits to deploy new hardware or software.Cisco UCS E-Series Servers address your changing business needs in the following ways:●Reduced operational burden: Through a consolidated, wire-free infrastructure, Cisco UCS E-Series Serversmake the addition of new services and infrastructure quick and easy.●Simplified system maintenance: Cisco UCS E-Series Servers ease physical server provisioning and systemmaintenance.●Enhanced server management: Built-in lights-out server management through the Cisco IntegratedManagement Controller (IMC) runs on the same dedicated baseboard management controller hardware found in all Cisco UCS products. This feature provides standalone management consistency with Cisco UCS C-Series Rack Servers for both local and remote server monitoring and configuration management.●Stronger physical security: The blades require no external network cables or physical keyboard, video, ormouse (KVM). They can therefore be easily secured in a wiring closet or other secure location withoutcompromising manageability, a situation that is difficult to achieve with traditional tower and rack-mountservers.●Small footprint: Cisco UCS E-Series Servers include multicore x86 64-bit Intel Xeon processors. You canreduce your branch-office server footprint by incorporating high-performance, power-optimized bladeservers directly into Cisco ISR G2 and 4000 Series branch-office routers. All are integrated and housed in a single Cisco ISR chassis, delivering an excellent all-in-one platform for the lean branch office.Platform Support and CompatibilityCisco UCS E-Series Servers are designed to support multiple bare-metal operating systems and hypervisors, including:●Operating systems◦Microsoft Windows Server◦Windows Server 2008 64-bit◦Windows Server 2008 R2 64-bit◦Windows Server 2012 64-bit◦Windows Server 2012 R2 64-bit◦Red Hat Enterprise Linux (RHEL) Release 6.2 and later◦SuSE Linux 11, Service Pack 2 and later◦Oracle Enterprise Linux 6.0, Update 2 and later●Hypervisors◦Microsoft Hyper-V 2008 R2, 2012, and 2012 R2◦VMware vSphere 5.0, Update 1, and Releases 5.1, 5.5, 6.0◦Citrix XenServer Release 6.0 and laterProduct SpecificationsTable 2 lists the specifications and Table 3 lists Cisco ISR support for the Cisco UCS E-Series M1 servers.

互联网将改变人类整个生活的理念已经深入人心1、建设背景:随着经济的蓬勃发展,为宾馆酒店业的发展提供了良好的机遇,丰厚的利润和巨大的市场也吸引了众多的竞争者,酒店行业靠什么赢得竞争优势?酒店在做好现有业务种类,不断提高服务水平的同时,如何把握客户的需求,用最经济的办法获得最大的客户满意度,提高企业自身的档次和知名度,同时拓展新的业务增长点,成为最根本的竞争所在,这使得酒店行业对信息化的需求非常迫切。

有调查表明,酒店的信息服务水平在很大程度上影响着客人的入住愿望。

无法提供高速互联网接入服务的酒店,对于客户来说,无疑是一场商业灾难。

2、上网需求渐增统计资料显示,酒店客户中85%的人有上网需求,并且其中有70%的客人提出了高速上网的要求。

值得注意的是,对上网速度有强烈需求的客户,对价格又不是很敏感,这些客人是各个酒店利润的主要来源,也是各大酒店竭力争取的商住客户或者常住客户。

因此,对于同等星级的酒店,在管理水平和房间设施趋于相近的情况下,提供高质量的互联网接入服务是酒店吸引更多商务客人入住的有效手段。

采用宽带接入可以显著提高星级酒店的信息化服务水平,酒店入住客人可以轻松自如地实现诸如网上冲浪、IP电话及可视电话、电视会议、电子商务、IPTV点播(互动点播电视节目和电影)、虚拟专用网络(VPN)等功能。

向客户提供高速上网,提高酒店的服务档次,是为了寻求酒店经济的增长点,提高酒店的竞争力。

通过传播酒店的声音,发布酒店的信息,开放酒店面向客户的信息,提供查询酒店信息的渠道,建立网络信访机制,可加深酒店与客人的感情。

通过广泛开展对酒店客人提供公益性的信息服务,例如新闻报道、天气预报、旅游指南、航班信息、求医问药和列车时刻查询等,可建设酒店的信息化环境。

设备外观
话归正题,咱们来看看今天的主角 — Cisco ISR G2 2921。

用外包装来看,和普通的ISR没有区别,只在于标签上的注释表明了这不是一台普通的路由器,而是一台ISR G2。

用小刀割开封装薄膜,将2921取出,第一感觉就是“沉”,比之前的28重了不是一个数量级,看来Cisco在用料方面还是相当的实在。

把2921放好,来几张PP。

上视图:
可以见到在机箱的上部出现了以往没有的“Cisco”的logo,表面同样是光滑无比,手感一流。

正面视图
机箱正面的布局有了很大的改变,将以往的白灰绿色调改为了黑绿相间,好不好看就见仁见智了,不过个人还是喜欢上一代产品的配色。

整体的做工还是更加的细致,包括机框纹理,电源按钮,指示灯等都做了优化,看得出Cisco在外观这块还是相当用心。

当然不可少的就是“2900”的标识,说明这就是一台如假包换的ISR G2
背面视图
背面的各种插槽也经过了重新的设计,有几处地方和ISR是不一样的。

详见下图:
1.2921有三个千兆电口,其中的Ge0/1是双介质,可以插光纤也可以插网线;
2.Console旁边的mini usb口可以接我们移动硬盘的数据线来进行调试,只要一段接路由器,另一端接电脑的usb口就可以,当然先需要在Cisco网站上下载相应的驱动。

(还
有很过分的一点是Cisco在ISR G2系列不送console线了,难道是强调低碳生活?)
3.还有个区别就是移动CF卡现在多了个固定的插槽,杜绝了CF卡弹出,路由器启动不正常的现象。

好了,外观的区别差不多就这样。

现在将2921加电。

跑起来了!
配置描述
看完了外观的描述,现在来看看系统配置方面的差异,还是用我们常用的几条命令来检查吧。

由上可以看到2921使用的是15.0的IOS版本,此版本无之前的Ipbase,advservice 等版本区别,要想使用高级的功能?咱这个版本都有,先花钱买lincense吧,自己升级版本的时代已经一去不复返了。

现在我们的版本是支持ipbase和voice的。

尾声
全文完,谨以此为纪念第一次与2921的亲密接触,希望大伙如能凭此文对29有个总体的了解。

如想了解29的其他功能,继续关注我们。
