Cisco 2500系列升级指南Cisco 2500系列升级指南（使用TFTP SERVER）1，准备：PC机一台，安装网卡，TFTP软件PC机一台，运行WINDOWS或WIN95仿真终端程序2，步骤：①设备连接：使用Cisco设备所带的Console线（黑色），连接2500的Console口和PC机的COM口，使用Cisco设备所带的双绞线（灰色），连接2500的AUI口（需要有AUI-AJ45的收发器）和TFTP SERVER的网卡RJ-45口。
②将升级软件拷贝至TFTP SERVER的相关目录下，启动TFTP SERVER。
③在PC机上通过终端仿真方式进入Cisco 2500的控制台在控制台方式下不要进入AUTOINSTALL方式，选择手动配置方式。
④在控制台状态下键入：router>en {进入特权模式}router#sh flash all {记录system images文件名}router#copy flash tftp {备份原有system images到tftp server}按提示输入TFTP SERVER的IP地址按提示输入SYSTEM IMAGES的文件名router#conf t {进入全局配置模式}router(config)#config-reg 0x2101 {修改寄存器值为 2101}router(config)#interface e0 {进入以太口配置模式}router(config-if)#ip address ##.##.##.## 255.255.255.0 {ip地址应与tftp server ip在同一网段}router(config-if)#no shutdown {激活端口}router(config-if)#^zrouter#reload {重新加载系统}router(boot)>enrouter(boot)#copy tftp flash {从tftp server升级IOS软件}按提示输入TFTP SERVER的IP地址按提示输入升级IOS源文件名按提示输入升级IOS目标文件名回车确认后，系统删除旧的IOS，开始从tftp server向router传输新的IOS文件.传输完成后键入：router(boot)#config trouter(boot)(config)#config-reg 0x2102 {将寄存器值改回2102}router(boot)(config)#^zrouter(boot)#reload。
各路由器密码找回方法
各路由器密码找回方法适用于所有的2000系列、2500系列、3000系列，以680x0为基准的4000系列，在ROM 中运行10.0或更高版本的IOS以后的7000系列，在ROM中运行9.1或更高版本的软件的IGS系列。
这里假定您的路由器的名字为“router”。
--------------------------------------------------------------------1、将一台终端或将PC以终端仿真的方式连到路由器的CONSOLE口上。
2、启动路由器到“router>”状态下，键入“show version”命令，此时记录下该命令的输出信息中的configration register的值（改值通常在该命令输出的最后一行），这个值通常应为0x2102或0x102。
例如：configration register is 0x2102。
3、将路由器的电源关掉，然后又重新开启。
4、在路由器启动后的60秒内请在终端上键入中断键（Break键或Ctrl_C键），您会看到一个前面没有路由器名字的>大于号）提示符。
如果没有出现，说明您没有给出正确的Break 信号，在这种情况下，请您检查终端仿真的设置。
5、在>号提示符下键入“o/r0x42”以便从Flash启动，注意第一个字母“o”不是十进制数“0”6、在>号提示符下键入“i”，路由器便会忽视存储的配置文件进行重新启动。
7、路由器启动后，对所有的setup的问题回答“no”。
8、在router> 提示符下键入“enable”，您就不需要口令就进入到enable模式，并且看到router# 提示符。
9、有两种方法可以改变enable口令：a. 删除所有的配置，键入“write erase”。
b. 不删除所有的配置，只删除enable的口令①.在router# 提示符下键入“config mem”。
②.在router# 提示符下键入“write term”。

cisoc路由器配置使用手册
CISCO路由器配置使用手册目录1．CISCO路由器基本知识.物理端口介绍.内存体系结构介绍.配置途径.命令行配置模式.路由器口令的安全管理.常用命令2．IP协议配置3．部分广域网协议配置协议配置配置配置4．IP路由协议配置.静态路由配置.缺省路由配置配置配置5．远程访问服务配置附录A：路由器口令恢复附录B：参考资料1．CISCO路由器基本知识CISCO路由器品种繁多，从低端的700系列到高端的12000系列，共有十多个系列，每个系列的硬件接口和结构都是不一样的，其市场定位也分为几个层次，如早期固定配置的800、2500系列路由器分别是面向家庭或小型办事处用户、小型企业广域网或远程拨号接入，Cisco7000系列路由器用于大型网络的分布层连接，12000系列为骨干网络的核心路由器。
现在的路由器都是模块化结构，用户根据需要选择网络模块和广域网接口卡，同时为以后升级提供了很大的灵活性，如3600系列拥有70种接口模块（ATM、E1、ISDNPRI、DIGITALMODEM等）可以选择，可以提供数据/语音、虚拟专网、拨号访问和多协议路由等解决方案。
其实，但从另一角度来说，路由器也是一台计算机，就象大家熟悉的运行WINDOWS95的PC机一样。
CISCO 路由器也包含硬件和软件两部分，其软件就是思科公司创造的网络操作系统：CiscoIOS （InternetworkOperatingSystem），掌握了IOS系统，也就掌握了路由器。
.路由器常用物理端口介绍Cisco路由器支持的部分物理接口类型包括：■以太网■快速以太网■令牌环网■FDDI■低速串口■高速串口■HSSI■ISDNBRI/PRI■ATM比如，CISCO2500系列包含以下几种端口：高速同步串口，最大支持的E1速率。
通过软件配置，这种端口可以连接DDN，帧中继（FrameRelay），，PSTN（模拟电话线路）。
同步/异步串口（sync/async），这种端口可以用软件设置工作方式。
CISCO路由器接口的配置
CISCO路由器的基本安装维护1 控制口连接先将CISCO2500/1000系列路由器附件中的控制电缆RJ45的一端连接到CISCO的CONSOLE口上,CISO7000/4000系列路由器则将MODEM电缆的DB25的一端接到CISCO 的CONSOLE口上，DB9的一端连接到PC的COM1/2上。
在PC上设置仿真终端程序：比如用WINDOWS中的TERMINAL程序，使用COM1/2，9600BPS，8 DATA BIT，2STOP BIT。
其余使用默认值。
做好控制口连接后，打开路由器的电源开关。
2 初始安装一般建议使用机器安装，这样既美观又便于维护。
！！！注意：路由器必须使用带有有效地的电源。
一般要求使用的电源的零地间的电压<4V，零火/地火的电压就为220V。
地线保护基本上要求上网的设备需有保护地线，这些设备包括主机、工作站、HUB、交换器、路由器及连接路由器的MODEM等。
配置路由器的终端或PC机也必须使用带有有效地的电源。
CISCO的同步串行接口是多用的，通过不同的电缆可引出不同的接口，如RS232、V.35等。
并且CISCO的同步串行接口电缆的电缆是特别预制的。
第一次安装时系统会自动进入DIALOG SETUP。
依次回答路由器名称，加密超级登录密码，超级登录密码，远程登录密码，动态路由协议，各个接口的配置等。
之后回答YES 保存该配置。
然后等2分钟,按回车数下。
出现路由器名称。
打入ENABLE命令，回答超级登录密码。
出现路由器名称＃。
打入CONFIG TERMINAL配置路由器：NO SERVICE CONFIGNO IP DOMAIN－LOOKUP（进一步的配置）按CTRL-Z退出，出现路由器名称＃。
打入WRITE MEMORY保存配置。

配置Cisco2500系列访问服务器你可以按下列几节中描述的程序之一配置访问服务器：✧使用配置方式(Configuration Mode)配置访问服务器✧使用自动安装(AutoInstall)配置访问服务器✧使用设置工具(Setup Facility)手工配置访问服务器按照最适合你的网络配置需要的程序做。
在继续配置过程前，输入show version命令检查访问服务器的当前状态。
show version 命令将显示在访问服务器上可用的Cisco IOS软件的版本。
●用配置方式配置访问服务器如果你不打算使用设置工具或自动安装的话，你可以手工配置访问服务器。
手工配置访问服务器采取以下几个步骤：步骤1、连接一个控制台终端，给访问服务器加电。
步骤2、当你被问到是否进入初始会话时，回答no，进入访问服务器正常的操作方式。
Would you like to enter the initial dialog? [yes]: no步骤3、几秒钟后，你会看到用户EXEC提示符(Router>)。
键入enable以进入授权方式(enable mode)。
改变配置只能在授权方式下做。
Router> enable提示符将变为特权EXEC提示符：router#步骤4、在授权提示符下键入config terminal命令，从终端进入配置方式：router# config terminal你现在可以键入你需要的任何对配置的改变。
要退出配置方式按Ctrl-Z 。
为了看到当前运行的配置，在#提示符下键入show running-config命令(如果你运行的是Cisco IOS 11.0或更高版本)。
键入命令write terminal (如果你运行的是Cisco IOS 11.0 以前的版本)router# show running-config为看到NVRAM中的配置，在授权提示符下键入show startup-config命令：router# show config为了使你的改变永久保留，在授权提示符后键入命令copy running-config startup- config(如果你运行的是Cisco IOS 11.0或更高版本)，或键入命令write terminal (如果你运行的是Cisco IOS 11.0以前的版本)router# copy running-config startup-config********如果你对配置做了改变但是还没有将它写入NVRAM，则show running-config和show startup-config命令的结果会不同。
现在访问服务器已经被配置，并将用你所输入的配置引导。
●用自动安装配置访问服务器自动安装程序AutoInstall是设计用于访问服务器连接到WAN后的自动配置的。
为使AutoInstall正确工作，你的网络上的一个TCP/IP主机必须预先配置成能够提供必需的配置文件。
TCP/IP主机可以在网络上的任何位置，只要能够维持下列两个条件：1. 主机必须在访问服务器对WAN的异步串行连接的远方场地。
2. 用户数据报协议(UDP)广播入出访问服务器，该TCP/IP主机必须被授权。
这个功能由你的系统管理员在该TCP/IP主机所在地点调整。
在TCP/IP主机上未提供必须的文件时，你不要试图使用AutoInstall。
采取以下步骤为AutoInstall程序准备你的访问服务器：步骤1、将异步串行电缆装至访问服务器。
步骤2、给访问服务器加电。
访问服务器将从闪速存储器装入操作系统映像。
如果WAN连接的远端被连接并正确地配置，AutoInstall程序将开始。
如果AutoInstall成功地完成，你可能要将配置数据写入访问服务器的非易失随机存取存储器(NVRAM)中。
执行下一个步骤完成这个任务：步骤3、如果你运行的是Cisco IOS 11.0或更高版本，请在#提示符后面输入copy running-config startup-config命令；如果你运行的是Cisco IOS 11.0以前的版本，输入write memory命令。
Hostname# copy running-config startup-config采取这些步骤将保存AutoInstall程序在访问服务器中生成的配置设定。
如果你未能作到这一点，你的配置将会在你下次加载访问服务器时丢失。
●用设置工具手工配置访问服务器如果你不打算使用AutoInstall，那就不要连接访问服务器的串行（WAN）电缆到通道服务单元/数据服务单元（CSU/DSU）。
这样就防止访问服务器试图运行AutoInstall程序。
不管你什么时候打开访问服务器，它都试图运行AutoInstall，只要串行(WAN)连接在两端连接而访问服务器又没有在NVRAM中保存一个配置。
访问服务器要确定AutoInstall未设置到一个远端TCP/IP主机上可能需要几分钟。
一旦访问服务器确认AutoInstal未被配置，它将默认设置工具。
如果串行(WAN)电缆没有连接，访问服务器将从闪速存储器引导并进入设置工具。
注意：任何时候你只要在授权提示符(#)后输入setup命令都可以运行设置工具。
配置全局参数当你第一次启动设置程序时你必须配置全局参数。
全局参数是用于控制整个系统的设置。
输入全局参数使用以下步骤：步骤1、连接一个控制台终端，然后引导访问服务器到EXEC提示符(router>)。
步骤2、在你从闪速存储器引导后大约30秒钟会出现下面的信息。
当你看到这些信息显示出来，你就已经成功地引导了你的访问服务器。
