cisco2600系列路由器故障排除
一、重啓進入了“rommon”狀態,重啓時顯示信息如下。
System Bootstrap, Version 11.3(2)XA4, RELEASE SOFTWARE (fc1)

rommon 1 >
二、在“rommon”下輸入命令後,顯示如下:
rommon 1 > dev
Devices in device table:
        id  name
    flash:  flash
rommon 2 > dir flash:
bad device name
usage: dir <device>
由此可見路由器上的Flash上沒有IOS或IOS損壞,得重新拷一個IOS到該系統。
三、進入“rommon”狀態。(開啓路由器的電源開關,並在30秒內按下鍵盤的Ctrl+break,中斷路由器的正常啓動以進入rom監視模式,屏幕上提示符如下: rommon 1> )在此狀態下輸入以下命令:
rommon 1 > xmodem flash   此時會顯示“警告”信息,並問是不是要“繼續”,你按“Y”。 然後,路由器一直等待從PC上接收該IOS映像文件。此時在超級終端軟件中點擊發送選項,選擇存放在PC本地硬盤中的IOS映像文件,確定後即開始下載文件至路由器的flash
rommon 1>
3) 鍵入xmodem命令:
rommon 1>xmodem c2600-is-mz.120-8.bin(IOS映像文件名)
4) 然後,路由器一直等待從PC上接收該IOS映像文件,此時在超級終端軟件中點擊發送選項,選擇存放在PC本地硬盤中的IOS映像文件,確定後即開始下載文件至路由器的flash
完成以後,會出現以下字幕:
Do not start the sending program yet...
device does not contain a valid magic number
dir: cannot open device flash:
WARNING: All existing data in flash will be lost!
Invoke this application only for disaster recovery.
Do you wish to continue? y/n:y
Ready to receive file c3640-i-mz.120-10.bin ...

program flash location 0x30380000

program load complete, entry point: 0x80008000, size:

5) 接着,路由器將自動重啓,屏幕顯示信息如下:
