上個月河南做項目,因需要大批量的對服務器進行操作系統的安裝,於是想到了PXE網絡批量安裝,
好不容易到機房的倉庫找到網線及一台思科交換機,但到安裝的時候,發現思科交換機里應該有配置了
通過配置線連接交換機,又發現又設置了enable密碼,於是筆者只能想到恢復初始配置,遂將實現過程整理如下:
1、按住前面板的mode鍵不放,插上電源,等3-5秒后松開mode鍵,我們將會看到如下提示:
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、到這里我們輸入flash_init命令,開始初始化flash,完了后,我們再輸入ren flash:config.text flash:config.old
命令對已存豐的config.text重新命名成config.old,不刪除、方便以后還可以恢復,最后我們在使用boot命令進行啟動
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、這樣我們等啟動好了,再次使用enable命令進入特權模式就沒有密碼了,還可以使用dir命令查看到我們重命名的文件,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#
