      思科路由器恢復(fù)IOS方法及開啟多用戶Telnet權(quán)限方法

      時(shí)間: 曉斌668 分享

        今天小編就給大家介紹下思科路由器交換機(jī)簡單的X-MODEM恢復(fù)IOS的方法以及開啟多用戶Telnet權(quán)限和Logo查看方法。

        首先小編就給大家介紹思科路由交換機(jī)簡單的X-Modem恢復(fù)IOS方法:

        1、用控制線連接思科路由交換機(jī)console口與計(jì)算機(jī)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(shè)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(yàn),無流控,停止位1?;蛘唿c(diǎn)擊默認(rèn)設(shè)置也可以。

        3、連接以后計(jì)算機(jī)回車出現(xiàn)思科路由交換機(jī)無ios的界面,一般的提示符是:switch:

        4、拔掉思科路由交換機(jī)后的電源線重新啟動交換機(jī)。

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

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

        7、系統(tǒng)提示不斷出現(xiàn)C這個字母就可以開始傳文件了。

        8、點(diǎn)擊超級終端菜單:傳送---發(fā)送文件,在協(xié)議選項(xiàng)中選擇Xmodem或者Xmodem-1K協(xié)議,然后選擇ios的影像文件(*.bin),開始傳送。

        9、因?yàn)椴荒芨乃俾?,所以傳送得很慢,我的大概傳送?0分鐘左右,請耐心等待。

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

        11、在提示符下輸入switch:boot,啟用新的ios系統(tǒng)。

        12、重新加電完成恢復(fù)工作。

        Cisco 路由器 使用Xmodem恢復(fù)IOS方法

        在沒有IOS的情況下 系統(tǒng)只能進(jìn)入Rommon狀態(tài),在這個狀態(tài)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 ? …

        然后在超級終端的傳送欄目=> 選擇發(fā)送選項(xiàng) => 再選擇Xmodem 并指明IOS所在的路徑即開始上傳IOS,等待時(shí)間很長,視IOS的大小和傳輸速度。對于初次做IOS上傳,建議不要去修改什么傳輸速率。傳完以后 對整個系統(tǒng)初始化 界面如下: [nextpage]
