Cisco Catalyst 3550/3750 交换机 enable密码清除，并保留原配置。

步骤如下：

1、将交换机console口与电脑相连，再按住交换机面板前的“mode”键，然后重启交换机，直到面板的”STAT”灯亮（如果不确定就一直按着半分钟，或直到手指酸），松开。

2、此时会出现命令提示符

switch:

如下：

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: flash_init

Initializing Flash?

flashfs[0]: 4 files, 1 directories

flashfs[0]: 0 orphaned files, 0 orphaned directories

flashfs[0]: Total bytes: 15998976

flashfs[0]: Bytes used: 8282624

flashfs[0]: Bytes available: 7716352

flashfs[0]: flashfs fsck took 11 seconds.

done Initializing Flash.

Boot Sector Filesystem (bs) installed, fsid: 3 Setting console baud rate to 9600?

switch: load_helper

switch: dir flash: 查看flash下的文件目录

2 -rwx 8276561 <date> c3750-ipservices-mz.122-37.SE.bin

3 -rwx 616 <date> vlan.dat

4 -rwx 5 <date> private-config.text

6 -rwx 3027 <date> config.text 7716352 bytes available (8282624 bytes used)

switch: rename flash:config.text flash:config.text.old

switch: boot

Loading “flash:/c3750-ipservices-mz.122-37.SE.bin”?@@@@

3、重启后进入ios进行如下操作：

Would you like to enter the initial configuration dialog? [yes/no]: no

~~Would you like to terminate autoinstall? [yes]: //选择yes 还原配置文件名称，并复制配置文件至running中~~

Switch>en

Switch#rename flash:config.text.old flash:config.text

Switch#copy flash:config.text system:running-config

Switch#configure terminal

Switch(config)#no enable password

Switch(config)#exit

Switch#wr

00:04:04: %SYS-5-CONFIG_I: Configured from console by console Building configuration? [OK]

交换机的enable密码被清除完成。
