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:
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:
