2、修改特权密码
1)首先在PT模拟器上建一个路由器，设置一个密码。
Router>
Router>en
Router#config
Configuring from terminal, memory, or network [terminal]?
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)#ena
Router(config)#enable p
Router(config)#enable password 123456
Router(config)#exit
Router#
%SYS-5-CONFIG_I: Configured from console by console
Router#write m
Router#write memory
Building configuration...
[OK]
Router#
2)在重设密码之前要重新启动路由器，在启动没完成之前按ctrl+c键进入rommon模式，然后输入以下命令，复制原文件到空白系统：
3)重新设置密码，，输入如下命令：
4)重新启动，再次进入rommon模式，进入正常模式，重新启动后需输入新密码。

1)在PT模拟器上连接一个服务器和路由器，如下图所示。
2)给服务器配一个地址。
3)在路由器上输入以下命令。
