忘了cisco 7609 的enable 密码,打算进行密码恢复

CISCO 7609的ENABLE密码恢复方法如下：
1、路由器接通电源后，按住CTRL+BREAK组合键。
2、此时CISCO路由器进入rommon模式。
3、接着利用CONFREG 0x214修改路由器的启动顺序。
4、然后点reset设置，CISCO路由器重启以后会不加载配置文件。
5、进入管理员模式，然后创建一个新密码即可。

加电后按住CTRL+break组合键，路由器会进入rommon模式，然后用confreg 0x214修改启动顺序，然后reset，路由器重启后会不加载配置文件，这样你就可以自由进入管理员模式。然后改一个新密码就可以了。

至于第二个问题，不知道LZ想说什么，cisco路由器默认情况用户模式当然不能show run和show ver，你是问怎么才能在用户模式下用这两条命令？？

这个其实很简单，先用管理员权限登进去，进入全局配置模式输入以下两条命令：

privilege exec level 1 show run
privilege exec level 1 show version

OK了。

⒈连接交换机的console口到终端或PC仿真终端。用无Modem的直连线连接PC的串行口到交换机的console口。
⒉先按住交换机面板上的mode键，然后打开电源。
⒊初始化flash。
>flash_init
⒋更名含有password的配置文件。
>rename flash:config.text flash:config.old
⒌启动交换机。
>boot
⒍进入特权模式。
>enable
⒎此时开机是已忽略password。
#rename flash:config.old flash:config.text
⒏copy配置文件到当前系统中。
#copy flash:config.text system:running-config
⒐修改口令。
#configure terminal
#enable secret
⒑保存配置。
#write

7600的恢复password的方法和普通的路由器是一样的，都是ctrl+Break进入rommon模式通过修改寄存器值来进行的。
只是需要注意下按ctrl+break的时间，如下是输出
