思科路由器恢復IOS方法及開啟多用戶Telnet權限方法

  今天小編就給大家介紹下cisco/' target='_blank'>思科路由器交換機簡單的X-MODEM恢復IOS的方法以及開啟多用戶Telnet權限和Logo查看方法。

  首先小編就給大家介紹思科路由交換機簡單的X-Modem恢復IOS方法:

  1、用控制線連接思科路由交換機console口與計算機串口1,用帶有xmodem功能的終端軟件連接(win2000 and xp的超級終端就帶這功能)。

  2、設置連接方式為串口1(如果連接的是其他串口就選擇其他串口),速率9600,無校驗,無流控,停止位1。或者點擊默認設置也可以。

  3、連接以後計算機回車出現思科路由交換機無ios的界面,一般的提示符是:switch:

  4、拔掉思科路由交換機後的電源線重新啟動交換機。

  5、在超級終端輸入:switch:flash_init,會出現如下提示:Initializing Flash...

  6、輸入拷貝指令:switch:copy xmodem: flash:image_filename.bin,出現如下提示:Begin the Xmodem or Xmodem-1K transfer now...

  7、系統提示不斷出現C這個字母就可以開始傳文件了。

  8、點擊超級終端菜單:傳送---發送文件,在協議選項中選擇Xmodem或者Xmodem-1K協議,然後選擇ios的影像文件(*.bin),開始傳送。

  9、因為不能改速率,所以傳送得很慢,我的大概傳送了80分鐘左右,請耐心等待。

  10、傳送完畢後提示:File "xmodem:" successfully copied to ....,switch:

  11、在提示符下輸入switch:boot,啟用新的ios系統。

  12、重新加電完成恢復工作。
 

  Cisco 路由器 使用Xmodem恢復IOS方法

  在沒有IOS的情況下 系統只能進入Rommon狀態,在這個狀態下只能見到如下命令:

  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

  在這個模式下,輸入Xmodem

  rommon 9 > xmodem

  會提示如下警告:

  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 ? …

  然後在超級終端的傳送欄目=> 選擇發送選項 => 再選擇Xmodem 並指明IOS所在的路徑即開始上傳IOS,等待時間很長,視IOS的大小和傳輸速度。對於初次做IOS上傳,建議不要去修改什麼傳輸速率。傳完以後 對整個系統初始化 界面如下: [nextpage]
