本實驗以WS-3550-48 SMI爲例,詳細描述對於2900xl/3500xl/2950/3550系列交換機的密碼恢復流程
一、將一臺終端或裝有超級終端軟件的PC接到交換機的console口上。終端參數設置如下:
速率:9600bps
速率:9600bps
校驗位:無
數據位:8
停止位:1
流控:無
二、撥掉電源
三、按住前面板的mode鍵不放,插上電源,等3-5秒後鬆開mode鍵。你會看到如下提示:
數據位:8
停止位:1
流控:無
二、撥掉電源
三、按住前面板的mode鍵不放,插上電源,等3-5秒後鬆開mode鍵。你會看到如下提示:
Interrupt within 5 seconds to abort boot process.
Boot process terminated.
The system is unable to boot automatically. The BOOT
environment variable needs to be set to a bootable
p_w_picpath.
switch:
switch: ?
? -- Present list of available commands
boot -- Load and boot an executable p_w_picpath
cat -- Concatenate (type) file(s)
copy -- Copy a file
delete -- Delete file(s)
dir -- List files in directories
flash_init -- Initialize flash filesystem(s)
format -- Format a filesystem
fsck -- Check filesystem consistency
help -- Present list of available commands
load_helper -- Load and initialize a helper p_w_picpath
memory -- Present memory heap utilization information
mkdir -- Create dir(s)
more -- Concatenate (display) file(s)
rename -- Rename a file
reset -- Reset the system
rmdir -- Delete empty dir(s)
set -- Set or display environment variables
set_param -- Set system parameters in flash
sleep -- Pause (sleep) for a specified number of seconds
trap -- Cause a software breakpoint to occur
-- MORE --
type -- Concatenate (type) file(s)
unset -- Unset one or more environment variables
四、輸入flash_init //初始化flash文件系統
五、輸入load _helper
六、輸入dir flash:
注意,不要少了flash後面的冒號,屏幕出現如下提示。
Directory of flash:/
五、輸入load _helper
六、輸入dir flash:
注意,不要少了flash後面的冒號,屏幕出現如下提示。
Directory of flash:/
3 -rwx 0 <date> env_vars
4 -rwx 344 <date> system_env_vars
5 -rwx 3624 <date> config.text
6 -rwx 5 <date> private-config.text
8 drwx 192 <date> c3550-i9q3l2-mz.121-14.EA1a
86 -rwx 5 <date> private-config.text.renamed
10243584 bytes available (5755392 bytes used)
七、輸入rename flash:config.text flash:config.old
switch: rename flash:config.text flash:config.old
八、輸入boot引導系統。
switch: boot
Loading "flash:c3550-i9q3l2-mz.121-14.EA1a/c3550-i9q3l2-mz.121-14.EA1a.bin"...##############################################################################################################################################################################################################################################################################################################################################################################################################
File "flash:c3550-i9q3l2-mz.121-14.EA1a/c3550-i9q3l2-mz.121-14.EA1a.bin" uncompressed and installed, entry point: 0x3000
executing...
九、當出現如下提示時,輸入N:
Continue with the configuration dialog? [yes/no] : N
十、用en進入enable狀態,並將文件config.old改回config.text,命令如下:
rename flash:config.old flash:config.text
十一、將原配置裝入內存,命令如下:
switch# copy flash:config.text system:running-config
十二、修改密碼:
switch#conf t
