拓扑图：
目的：
掌握基本接口ip地址配置，熟悉基本telnet登陆设置
步骤：
1.
查看相关接口连接
Router#show ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES unset administratively down down
Serial1/0 unassigned YES unset administratively down down
Serial1/1 unassigned YES unset administratively down down
Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
2.
配置主机名以及相关参数
Router#conf t
Router(config)#host R1
R1(config)#no ip domain-lo
R1(config)#line con 0
R1(config-line)#no exec-t
R1(config-line)#exit
R1(config)#
R1(config)#
R1(config)#
3.
配置串口ip地址
R1(config)#interface serial 1/1
R1(config-if)#ip add
R1(config-if)#ip address 10.10.12.1 255.255.255.0
R1(config-if)#clock rate 64000
R1(config-if)#no shutdown
R1(config-if)#end
R1#sh ip interface brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES unset administratively down down
Serial1/0 unassigned YES unset administratively down down
Serial1/1 10.10.12.1 YES manual up up

Serial1/2 unassigned YES unset administratively down down
Serial1/3 unassigned YES unset administratively down down
8.
测试ip连通性
R1#ping 10.10.12.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.12.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/38/72 ms
R1#ping 192.168.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
.!!!!-
Success rate is 80 percent (4/5), round-trip min/avg/max = 16/27/44 ms
9.
配置从R2 telnet 到R1的基本设置
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#enable password cisco
R1(config)#line vty 0 4
R1(config-line)#password cisco
R1(config-line)#login
R1(config-line)#end
10.
从R2上登陆到R1测试
R2#telnet 10.10.12.1
Trying 10.10.12.1 ... Open
User Access Verification
Password: ---------------------------------------------vty线下密码
R1>enable
Password: ----------------------------------------------enable密码
R1#------------------------------------------------------成功登陆到R1上
按q退出登陆
R1#q
[Connection to 10.10.12.1 closed by foreign host]
R2#
11.
配置基于用户名telnet登陆方式
R1#conf t
R1(config)#enable password cisco
R1(config)#username wmzhe password cisco
R1(config)#line vty 0 4
R1(config-line)#login local
R1(config-line)#end
12.
从R2上测试登陆方式：
R2#telnet 10.10.12.1
Trying 10.10.12.1 ... Open
User Access Verification
Username: wmzhe
Password:
R1>enable
Password:
R1#q
[Connection to 10.10.12.1 closed by foreign host]
R2#
13.
同样道理也可以通过以太网口telnet
R2#telnet 192.168.1.1
Trying 192.168.1.1 ... Open
User Access Verification
Username: chaijian
Password:
R1>enable
Password:
R1#q
