CISCO路由器版本升级指导书

CISCO路由器版本升级说明

在桂林地区114工程中，局方在县局联网将要完工时要求我们在网络系统增加IPX协议，以备97工程的NOVELL服务器联网。当时7507路由器软件带IPX协议，但县局2501路由器不带IPX协议，CISCO 路由器软件放在FLASH MEMERY 芯片里，不同的软件件版本带不同的协议，价钱也不一样，为了赶时间和免除商务上的麻烦，我们通过INTERNET与CICSO公司联系，借邮电局的面子，免费取得TFTP SERVER 软件和具有TCP/IP，IPX

协议的IOS 软件，下面是CISCO路由器软件升级的过程说明。

1.在interne上的CISCO 站点下载software&support/software centes/other software/tftp server for windows 95/TFTPSRVR.ZIP 文件，此文件用UNZIP 打

开后包含四个文件:TFTPSRV.EXE, TFTPSERV.DLL, MFC42.DLL , MSVCRT.DLL,将三个DLL文件拷到WIN95 C:\WINDOWS\SYSTEM目录下.

2.通过CISCO公司在internet上下载所需IOS BIN文件（经CISCO北京办事处授权，取

得密码，才能下载IOS软件）

3.在WIN95上运行TFTPSRV.EXE,并在option 选项中指定BIN 文件路径

4.在微机上通过仿真终端运行COPY TFTP FLASH 命令

出现Address or name of remote host [255.255.255.255]?时输入相应运行TFTPSRV.EXE微机的IP地址.如168.68.100.100。

Source file name?要求输入TFTPSRV 所指定目录IOS BIN 文件,如gs-in-l_110-19(3).bin Destination file name?要求输入加载到FLASH MEMERY 的IOS 文件名,可以与Source file name 一至如[igs-in-l_110-19(3).bin]?

遇到其他他选项,都按Y或回车, 路由器就开始清除FLASH MEMERY的IOS文件,然后通过TFTP SERVER把新的IOS 文件COPY 到FLASH MEMERY里, 软件更换换完后出现路由器名> ,IOS软件更换不会改变原路由器的设置,如名称,密码,IP地址等都与原设置一样.

5有时软件更换后,路由器启动时不是取FLASH MEMERY 的IOS 软件而是取BOOT ROOM 的软件,此时显示路由器名(boot)>.用sh ver 和sh flash 可看到两个版本不一致(FLASH MEMERY理的软件才是更换后的软件)。遇到这种情况就要进入路由器运行:

***(boot)#conf t

y114(boot)(config)#config-register 0x2102

***(boot)(config)#exit

***(boot)#reload

启动后,路由器就会使用FLASH

MEMERY中的软件.

Password:

lc114#copy tftp flash

**** NOTICE ****

Flash load helper v1.0

This process will accept the copy options and then terminate

the current system image to use the ROM based image for the copy.

Routing functionality will not be available during that time.

If you are logged in via telnet, this connection will terminate.

Users with console access can see the results of the copy operation.
