远程登录：


主机进入终端模式;

1 2 3 4 5 6 7 8 9 10 11 12 13

Router>enable Router#conf t Router(config)#enable secret 123456     //设置enable密码 Router(config)#line vty 0 4            //设置远程登录机数为5台 Router(config-line)#password cisco      //远程登录密码为cisco Router(config-line)#login          //登录时验证 Router(config-line)#exit Router(config)#interface fa 0/0 Router(config-if)#ip addre Router(config-if)#ip address 10.2.3.254 255.255.255.0  //给接口配置IP地址，远程机的网关 Router(config-if)#no shut Router(config-if)#end

单臂路由

两个VLAN之间的通讯可以通过一个路由器解决。
交换机：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

Switch>enable Switch#conf t Enter configuration commands, one per line.  End with CNTL/Z.
