上个月河南做项目,因需要大批量的对服务器进行操作系统的安装,于是想到了PXE网络批量安装,
好不容易到机房的仓库找到网线及一台思科交换机,但到安装的时候,发现思科交换机里应该有配置了
通过配置线连接交换机,又发现又设置了enable密码,于是笔者只能想到恢复初始配置,遂将实现过程整理如下:
1、按住前面板的mode键不放,插上电源,等3-5秒后松开mode键,我们将会看到如下提示:
The system has been interrupted prior to initializing the
flash filesystem. The following commands will initialize
the flash filesystem, and finish loading the operating
system software:
flash_init
load_helper
boot
switch:
2、到这里我们输入flash_init命令,开始初始化flash,完了后,我们再输入ren flash:config.text flash:config.old
命令对已存丰的config.text重新命名成config.old,不删除、方便以后还可以恢复,最后我们在使用boot命令进行启动
switch: flash_init Initializing Flash... flashfs[0]: 18 files, 2 directories flashfs[0]: 0 orphaned files, 0 orphaned directories flashfs[0]: Total bytes: 7741440 flashfs[0]: Bytes used: 3966464 flashfs[0]: Bytes available: 3774976 flashfs[0]: flashfs fsck took 6 seconds. ...done initializing flash. Boot Sector Filesystem (bs:) installed, fsid: 3 Parameter Block Filesystem (pb:) installed, fsid: 4 switch: dir List of filesystems currently registered: flash[0]: (read-write) xmodem[1]: (read-only) null[2]: (read-write) bs[3]: (read-only) switch:
3、这样我们等启动好了,再次使用enable命令进入特权模式就没有密码了,还可以使用dir命令查看到我们重命名的文件,如下所示:
Switch>en Switch#dir Directory of flash:/ 2 -rwx 2664051 Mar 01 1993 00:03:22 c2950-i6q4l2-mz.121-11.EA1.bin 4 -rwx 1216 Apr 15 1994 21:28:58 vlan.dat 5 -rwx 4413 Jan 31 1994 21:45:53 config.old 6 -rwx 5 Jan 31 1994 21:45:53 private-config.text 7 drwx 704 Mar 01 1993 00:04:00 html 19 -rwx 109 Mar 01 1993 00:04:01 info 20 -rwx 109 Mar 01 1993 00:04:01 info.ver 21 -rwx 269 Jan 01 1970 00:01:46 env_vars 7741440 bytes total (3774976 bytes free) Switch#
