disconnect 1------主动释放某台路由器 show user --------显示连接到总路由器的用户 clear line 19 ---踢除某个用户
clear line 5 ----踢除 5 号线所连设备
quit/exit----------退出总路由器，释放所有路由器
实验二： R1： enable -----进入特权模式 disable-----从特权模式返回到用户模式 enable -----再次进入特权模式 config terminal----进入全局模式 exit ----返回上一层 相当于 DOS 环境中的 cd.. config terminal interface serial0 ---进入接口模式（26xx 系列路由器如：r5 则使用 serial0/0） ip address 192.168.51.1 255.255.255.0 clock rate 64000 ----配置时钟(DCE) no shutdown -----------激活启用当前接口 end------返回到最顶层 相当于 DOS 环境中的 cd\ config terminal hostname r100----给路由器命名(区分大小写 r1，从通信服务器转过来还用线名 r1，非路由器名) end disable ping 192.168.xy.x/y !!!!!---拼通 .....---查错
