思科 路由器 如何刷固件

  在对能够正常启动的CISCO路由器的IOS进行升级时,比较简单。具体步骤如下:

  1、寻找一种汪闷升TFTP服务器软件(有CISCO公司的TFTPServer或3COM公司的3Cserver等,在升级较大IOS映象文件时,建议用3Cserver),安装在一台计算机上,将要升级的IOS
  映象文件拷贝到相关的目录中(例:D:\),并运行TFTP服务器软件,通过菜单设置Root
  目录为拷贝IOS映象文件所在目录(如D:\)。假设该计算机的IP地址为10.32.10.1;

  2、连接路由器的console口与PC机的COM1,使用PC的超级终端软件访问路由器,将路由器的地址设为10.32.10.32(与计算机的IP地址同网段即可)。建议在进行IOS升级前将原有IOS文件备份下来,防止待升级的IOS文件存在问题不可用;
  Router# dir flash: (查看目前IOS映象文件名,也可用Router#Show version)
  Directory of flash:/
  1 -rw- 5998292 C2600-I-MZ.122-11.BIN
  8388608 bytes total (2390252 bytes free)
  Router#
  copy flash tftp(备份IOS文件)
  Source filename []?c2600-i-mz.122-11.bin
  Address or name of remote host []?10.32.10.1 (TFTP服务器地址)

  Destination filename [c2600-i-mz.122-11.bin]?
  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  Router#

  3、对路由器进行困老IOS升级;
  Router#
  copy tftp flash
  Address or name of remote host []?10.32.10.1 (TFTP服务器地址)
  Source filename []?c2600-i-mz.122-11.bin (需升级的新罩空IOS映象文件名)
  Destination filename [c2600-i-mz.122-11.bin]?
  Do you want to over write? [confirm]
  Accessing tftp://10.32.10.1/c2600-i-mz.122-11.bin...
  Erase flash: before copying? [confirm]
  Erasing the flash filesystem will remove all files! Continue? [confirm]
  Erasing device... eeeeeeeeeeeeeeeeeeeeee ...erasedee
  Erase of flash: complete
  Loading c2600-i-mz.122-11.bin from 10.32.10.1 (via
  Ethernet0/0): !!!!!!!!!
  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  „
  !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
  [OK - 5998292 bytes]
  Verifying checksum... OK (0xA0C0)
  5998292 bytes copied in 318.282 secs (18846 bytes/sec)
  Router#
