设备配置的准备工作
修改会话超时时间，设置为永不超时。
Router(config)#line console 0 Router(config-line)#exec-timeout 0 0
防止控制台自动显示的信息，可以启用显示同步。
Router(config)#line console 0 Router(config-line)#logging synchronous
禁用DNS查询
Router(config)#no ip domain-lookup
显示当前路由所有操作过的命令
Router#show running-config
给路由配置IP地址
Router(config)#interface fastEthernet 0/0 Router(config-if)#ip address 192.168.1.1 255.255.255.0 Router(config-if)#no shutdown \\开启路由接口
给交换机配置IP地址
Switch(config)#interface vlan 1 Switch(config-if)#ip address 192.168.1.1 255.255.255.0 Switch(config-if)#no shutdown
配置实例
路由器的f0/0与交换机的f0/1接在一起 通过PC连接设备的Console口 为设备配置IP地址 实现设备间的互通。
