思科路由器恢复IOS方法及开启多用户Telnet权限方法

晓斌分享

  今天小编就给大家介绍下思科路由器交换机简单的X-MODEM恢复IOS的方法以及开启多用户Telnet权限和Logo查看方法。

  首先小编就给大家介绍思科路由交换机简单的X-Modem恢复IOS方法:

  1、用控制线连接思科路由交换机console口与计算机串口1,用带有xmodem功能的终端软件连接(win2000 and xp的超级终端就带这功能)。

  2、设置连接方式为串口1(如果连接的是其他串口就选择其他串口),速率9600,无校验,无流控,停止位1。或者点击默认设置也可以。

  3、连接以后计算机回车出现思科路由交换机无ios的界面,一般的提示符是:switch:

  4、拔掉思科路由交换机后的电源线重新启动交换机。

  5、在超级终端输入:switch:flash_init,会出现如下提示:Initializing Flash...

  6、输入拷贝指令:switch:copy xmodem: flash:image_filename.bin,出现如下提示:Begin the Xmodem or Xmodem-1K transfer now...

  7、系统提示不断出现C这个字母就可以开始传文件了。

  8、点击超级终端菜单:传送---发送文件,在协议选项中选择Xmodem或者Xmodem-1K协议,然后选择ios的影像文件(*.bin),开始传送。

  9、因为不能改速率,所以传送得很慢,我的大概传送了80分钟左右,请耐心等待。

  10、传送完毕后提示:File "xmodem:" successfully copied to ....,switch:

  11、在提示符下输入switch:boot,启用新的ios系统。

  12、重新加电完成恢复工作。

  在没有IOS的情况下 系统只能进入Rommon状态,在这个状态下只能见到如下命令:

  rommon 8 > ?

  alias set and display aliases command

  boot boot up an external process

  break set/show/clear the breakpoint

  confreg configuration register utility

  cont continue executing a downloaded image

  context display the context of a loaded image

  cookie display contents of cookie PROM in hex

  dev list the device table

  dir list files in file system

  dis display instruction stream

  dnld serial download a program module

  frame print out a selected stack frame

  help monitor builtin command help

  history monitor command history

  meminfo main memory information

  repeat repeat a monitor command

  reset system reset

  set display the monitor variables

  stack produce a stack trace

  sync write monitor environment to NVRAM

  sysret print out info from last system return

  tftpdnld tftp image download

  unalias unset an alias

  unset unset a monitor variable

  xmodem x/ymodem image download

  在这个模式下,输入Xmodem

  rommon 9 > xmodem

  会提示如下警告:

  WARNING: All existing data in bootflash will be lost!

  Invoke this application only for disaster recovery.

  Do you wish to continue? y/n [n]: y

  Ready to receive file ? …

  然后在超级终端的传送栏目=> 选择发送选项 => 再选择Xmodem 并指明IOS所在的路径即开始上传IOS,等待时间很长,视IOS的大小和传输速度。对于初次做IOS上传,建议不要去修改什么传输速率。传完以后 对整个系统初始化 界面如下: [nextpage]
