3.对于Catalyst 2955系列来说: Catalyst 2955没有没有外部的Mode按钮,因此就不能使用之前的那种方法来进行密码恢复.在交换机启动时,对于Windows系列的PC,按下Ctrl+Break键;对于UNIX系列的工作站,按下Ctrl+C.如下: C2955 Boot Loader (C2955−HBOOT−M) Version 12.1(0.0.514), CISCO DEVELOPMENT TEST VERSION Compiled Fri 13−Dec−02 17:38 by madison WS−C2955T−12 starting...

不进入setup模式: −−− System Configuration Dialog −−− At any point you may enter a question mark '?' for help. Use ctrl−c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'. Continue with configuration dialog? [yes/no]: n
保存配置: Switch#write memory Building configuration... [OK] Switch#
搞定了@_@
4.对于Catalyst 3550/3750系列来说: 1.通过带有支持Xmodem协议的超级终端程序的PC连接到交换机的console口,把波特率设置为9600。 2.拔掉交换机的电源。 3.按下交换机上的Mode按钮,与此同时,重新插上交换机的电源线。当交换机端口1X上的LED熄灭后可以松开Mode按钮1到2秒,之后将显示一些指示信息: The system has been interrupted prior to initializing the flash file system. The following commands will initialize the flash file system, and finish loading the operating system software: flash_init load_helper boot switch# 4.初始化flash文件系统: switch#flash_init 5.加载帮助文件: switch#load_helper 6.显示闪存里的内容: switch#dir flash: 7.重命名配置文件: switch#rename flash:config.text flash:config.text.old 8.启动系统,并且如果提示进入setup模式,输入N: switch#boot Continue with the configuration dialog? [yes/no]: N 9.进入特权模式,把配置文件名恢复为原始文件名: Switch#rename flash:config.text.old flash:config.text 10.把配置文件写进内存: Switch#copy flash:config.text system:running-config Source filename [config.text]? Destination filename [running-config]? 11.进入全局配置模式更改密码: Switch(config)#enable secret {password} 12.退出,并保存到startup-config文件里: Switch(config)#copy running-config startup-config
