Cisco基础实验回顾2--通过Telnet访问路由器

go4321

　　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:
　　Reply from 172.16.0.1: bytes=32 time=125ms TTL=255
　　Reply from 172.16.0.1: bytes=32 time=63ms TTL=255
　　Reply from 172.16.0.1: bytes=32 time=62ms TTL=255
　　Reply from 172.16.0.1: bytes=32 time=62ms TTL=255
　　Ping statistics for 172.16.0.1:
　　Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
　　Approximate round trip times in milli-seconds:
　　Minimum = 62ms, Maximum = 125ms, Average = 78ms
　　PC>telnet 172.16.0.1
　　Trying 172.16.0.1 ...
