Cisco基础实验回顾2--通过Telnet访问路由器

实验拓扑：

通过直通线连接设备，手动先设置PC的IP地址。





路由器上的操作：

Router>en

Router#conf ter

Enter configuration commands, one per line. End with CNTL/Z.

1. 配置接口IP地址：

Router(config)#int fa0/0

Router(config-if)#ip address 172.16.0.1 255.255.0.0

Router(config-if)#no shut

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#end

2. 配置路由器密码：

Router#conf ter

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#line vty 0 4

Router(config-line)#password cisco

Router(config-line)#login

Router(config-line)#exit

Router(config)#enable password cisco

Router(config)#end

PC上的操作：

PC>ping 172.16.0.1

Pinging 172.16.0.1 with 32 bytes of data:
